Sonic 2 Beta 6



These five betas, labeled Beta 4 to Beta 8 in the Sega QA Archives, are internal testing builds spanning eight days that were created as the Sonic the Hedgehog 2 project was nearing completion. All six were released by drx as part of the colossal February 23, 2008 proto dump.




Sonic 2 Beta 6



Te pięć wersji beta, oznaczonych Beta 4 do Beta 8 w Sega QA Archives to wewnętrzne kompilacje testowe obejmujące osiem dni, które zostały utworzone gdy produkcja Sonic the Hedgehog 2 zbliżała się ku końcowi. Wszystkie sześć zostało wydanych przez drx jako część kolosalnego zrzutu prototypów 23 Lutego, 2008.


We wszystkich wersjach beta Sonic może zachować swoją supertransformację na koniec aktu. Suma pierścieni na ekranie wyników będzie równa liczbie pierścieni, które gracz miał, gdy minął drogowskaz.


Beta 4 do Beta 6 nie pokażą obiektów zmieniacza kolizji w trybie debugowania, nawet jeśli włączony jest tryb edycji. W wersji beta 7-8 obiekty zmieniacza kolizji są zawsze widoczne tak długo, jak aktywny jest tryb debugowania. W wersjach detalicznych obiekty te są widoczne tylko w trybie edycji.


W Beta 7 i 8 wiadomość będzie migać, nawet gdy gracz zdobędzie wystarczającą liczbę pierścieni. Żółte części sceny od czasu do czasu migają różnymi kolorami, w tym zielonym, czerwonym i białym. Wynika to ze zbyt wczesnego ładowania palety cyklicznej używanej dla pierścieni, które zaznaczają koniec każdej sekcji. W wersji beta 4 tło nie miga w różnych kolorach podczas zdobywania siódmego Szmaragdu Chaosu.

ESE2 is another popular level editor, working with Sonic 1, Sonic 2(its beta too), and Sonic 3k, its tools include a Layout editor, a Palette editor (a very good one), an Object editor, and a tile editor. I recommend using this as your main editor, but yet SonED does have some special quality's as in seeing the sky in the layout editor, and other useful things, if these two apps are used properly together they can produce some pretty good maps!


A mutant of Saccharomyces cerevisiae highly resistant to 2-amino-4-methyl-5-beta-hydroxyethylthiazole (2-aminohydroxyethylthiazole), an antimetabolite of 4-methyl-5-beta-hydroxyethylthiazole (hydroxyethylthiazole), has been isolated. Its resistance to 2-aminohydroxyethylthiazole was about 10(4) times that of the sensitive parent strain. The amount of thiamin synthesized in the cells of the resistant strain grown in minimal medium was less than half of that of the sensitive strain. The ability to synthesize thiamin from 2-methyl-4-amino-5-hydroxymethylpyrimidine (hydroxymethylpyrimidine) and hydroxyethylthiazole in the resistant strain was low compared with that of the sensitive strain. These results were found to be due to a deficiency of hydroxyethylthiazole kinase in the resistant strain: in sonic extracts of cells the enzyme activity was only 0.67% of that of the sensitive strain. Although the cells of the sensitive strain could accumulate exogenous hydroxyethylthiazole in the form of hydroxyethylthiazole monophosphate, no significant uptake of hydroxyethylthiazole by the cells of the resistant strain was observed. The possibilities that 2-aminohydroxyethylthiazole monophosphate may be the actual inhibitor of the growth of Saccharomyces cerevisiae, and that hydroxyethylthiazole may not be involved in the pathway of de novo synthesis of thiamin via hydroxyethylthiazole monophosphate, are discussed.

We have put together a Street Fighter 6 beginner's guide that includes the useful tips you need to know to get started. Featured here you'll find who we think are the best characters to play in Street Fighter 6 based on your skill level and preferred playstyle, their move lists, useful attacks, and even some basic combos to get you started.


Myth or fact? Myth, based on fact. There was indeed going to be a zone called the Hidden Palace Zone, as the previews showed, but it was inaccessible in the final version of the game. The reason is because the company scrapped the level before the game was released due to time issues. It was initially going to be, according to Sonic creator Yuji Naka, a special way to introduce Super Sonic. Yuji also went on to point out that the Hidden Palace Zone was not the only zone removed from the game, and that an old beta of the game did indeed contain the zone, or rather half of the zone, which was as far as the Hidden Palace made it before being scrapped. Gamers have reported being able to access the zone (or rather the first half of the zone, since that is all that was actually made) utilizing a Game Genie, though we are unable to confirm this at this time.

There are a few topics which we currently cover on articles such as Pokémon Red and Green and Pokémon Ruby and Sapphire beta which aren't necessarily 'beta' as such, 'beta' is not synomonous with unused. If something is beta it means means that sufficient attempts have been made at testing it, debugging any problems around it and consideration of implementing it into the final game (after testing to see if it is suitable, the possible technical limitations, etc.)


_Sun_and_Moon Sun and Moon have enough information to warrant a page currently. Will try getting to creating it when I am able to, going to go through other beta pages first and see if there is more info I can add currently. I will need to make an account over at tcrf soon so I can ask for permission to use their images here. Frozen Fennec 23:46, 18 July 2017 (UTC)


cut EVOLUTIONARY HOMOLOGS Characterization of mammalian Cut homologsClox (Cut-like homeo box) is a mammalian homeobox gene related to Drosophila cut. Both Clox and CDP have the same preferred DNA-binding specificity (Andres, 1992). Clox (Cut-like homeo box) and CDP (CCAAT displacement protein), two mammalian counterparts of the Drosophila Cut homeo protein, correspond to alternatively spliced products of the same gene. The human Cut homeodomain represses transcription from the c-myc promoter, suggesting a role for Cut in regulation of the cell cycle (Dufort, 1994). Not all CDP binding sites contain CCAAT boxes. Cut repeats function as novel DNA binding motifs. Each repeat exhibits sequence specific DNA binding, and the specificity of each repeat differs. Both the homeodomain and the Cut repeat bind to DNA (Aufiero, 1994). Ectopic expression in the fly of the human protein CDP and the murine protein Cux as well as Cut, similarly affects embryonic sensory organ development and can rescue a wing scalloping mutant phenotype associated with loss of cut expression along the prospective wing margins. This suggests that the function of Cut is evolutionarily conserved (Ludlow, 1996).Hepatocyte nuclear factor-6 (HNF-6) is a liver-enriched transcription factor that contains a single cut domain and a novel type of homeodomain. The developmental expression pattern of HNF-6 has been studied in the mouse. In situ hybridization experiments showed that HNF-6 mRNA is detected in the liver at embryonic day (E) 9, at the onset of liver differentiation. HNF-6 mRNA disappears transiently from the liver between E12.5 and E15. In transfection experiments, HNF-6 stimulates the expression of HNF-4 and of HNF-3 beta, two transcription factors known to be involved in liver development and differentiation. HNF-6 is detected in the pancreas from E10.5 onward, where it is restricted to the exocrine cells. HNF-6 is also detected in the developing nervous system. Both the brain and the spinal cord start to express HNF-6 at E9-9.5 in postmitotic neuroblasts. Later, HNF-6 is restricted to brain nuclei, to the retina, to the ventral horn of the spinal cord, and to dorsal root ganglia. The observations that HNF-6 contributes to the control of the expression of transcription factors and is expressed at early stages of liver, pancreas, and neuronal differentiation suggest that HNF-6 regulates several developmental programs (Landry, 1997). DNA-binding of Cut homologsA characteristic feature of the Cut homeo proteins is the presence of three evolutionarily conserved 73-amino-acid repeats of unknown function, the so-called Cut repeats. The Cut repeat II binds to Clox consensus targets independently of the DNA-binding activity of the homeodomain. In vitro selection of binding sites shows that the optimal targets for the Cut repeat II contain one or more CCAAT boxes and, like the homeodomain, an ATTA core. The Clox homeo domain and Cut repeat II interact in vitro in the absence of DNA. This interaction, which greatly enhances the DNA-binding activity of the binary complex, is specific to the Cut homeo proteins (Andres, 1994).The Drosophila and mammalian Cut homeodomain proteins contain, in addition to the homeodomain, three other DNA binding regions called Cut repeats. Cut-related proteins thus belong to a distinct class of homeodomain proteins with multiple DNA binding domains. Using nuclear extracts from mammalian cells, Cut-specific DNA binding is increased following phosphatase treatment, suggesting thatendogenous Cut proteins are phosphorylated in vivo. Sequence analysis of Cut repeats reveals the presence of sequences that match the consensus phosphorylation site for casein kinase II (see Drosophila CKII). Therefore, an investigation was carried out to determine whether CKII can modulate the activity of mammalian Cut proteins. In vitro, a purified preparation of CKII efficiently phosphorylated Cut repeats, causing an inhibition of DNA binding. In vivo, overexpression of the CKII alpha and beta causes a decrease in DNA binding by Cut. The CKII phosphorylation sites within the murine Cut (mCut) protein have been identified by in vitro mutagenesis as residues Ser400, Ser789, and Ser972 within Cut repeats 1, 2, and 3, respectively. Cut homeodomain proteins are known to function as transcriptional repressors. Overexpression of CKII reduces transcriptional repression by mCut, whereas a mutant mCut protein containing alanine substitutions at these sites is not affected. Altogether these results indicate that the transcriptional activity of Cut proteins is modulated by CKII (Coqueret, 1998a). The CCAAT displacement protein/Cut homeobox (CDP/Cux) transcription factor is expressed as multiple isoforms that may contain up to four DNA-binding domains: Cut repeats 1, 2, and 3 (CR1, CR2, CR3) and the Cut homeodomain (HD). The full-length protein, which contains all four DNA-binding domains, is surprisingly less efficient than the shorter isoforms in DNA binding. Using a panel of recombinant proteins expressed in mammalian or bacterial cells, a domain has been identified at the extreme N terminus of the protein that can inhibit DNA binding. This domain was able to inhibit the activity of full-length CDP/Cux and of proteins containing various combinations of DNA-binding domains: CR1CR2, CR3HD, or CR2CR3HD. Since inhibition of DNA binding was also observed with purified proteins obtained from bacteria, it is concluded that autoinhibition does not require post-translational modification or interaction with an interacting protein but instead functions through an intramolecular mechanism. Antibodies directed against the N-terminal region are able to partially relieve inhibition. In vivo, the transition between the inactive and active states for DNA binding is likely to be governed by posttranslational modifications and/or interaction with one or more protein partners. In addition, the relief of autoinhibition can be accomplished via the proteolytic processing of CDP/Cux. Altogether, these results reveal a novel mode of regulation that serves to modulate the DNA binding activity of CDP/Cux (Truscott, 2005).Mutation of Cut homologsMurine CDP/Cux, a homologue of the Drosophila Cut homeoprotein, modulates the promoter activity of cell cycle-related and cell-type-specific genes. CDP/Cux interacts with histone gene promoters as the DNA binding subunit of a large nuclear complex (HiNF-D). CDP/Cux is a ubiquitous protein containing four conserved DNA binding domains: three Cut repeats and a homeodomain. This study analyzed genetically targeted mice (Cutl1tm2Ejn, referred to as DeltaC) that express a mutant CDP/Cux protein with a deletion of the C terminus, including the homeodomain. In comparison to the wild-type protein, indirect immunofluorescence showed that the mutant protein exhibits significantly reduced nuclear localization. Consistent with these data, DNA binding activity of HiNF-D is lost in nuclear extracts derived from mouse embryonic fibroblasts (MEFs) or adult tissues of homozygous mutant (DeltaC-/-) mice, indicating the functional loss of CDP/Cux protein in the nucleus. No significant difference in growth characteristics or total histone H4 mRNA levels was observed between wild-type and DeltaC-/- MEFs in culture. However, specific histone genes (H4.1 and H1) containing CDP/Cux binding sites have reduced expression levels in homozygous mutant MEFs. Stringent control of growth and differentiation appears to be compromised in vivo. Homozygous mutant mice have stunted growth (20% to 50% weight reduction), a high postnatal death rate of 60% to 70%, sparse abnormal coat hair, and severely reduced fertility. The deregulated hair cycle and severely diminished fertility in Cutl1tm2Ejn/tm2Ejn mice suggest that CDP/Cux is required for the developmental control of dermal and reproductive functions (Luong, 2002).Cut regulation by cell cycle mediatorsCut is a homeodomain transcription factor which has the unusual property of containing several DNA-binding domains: three regions (termed Cut repeats) and the Cut homeodomain. Genetic studies in Drosophila indicate that cut plays important roles in the determination and maintenance of cell-type specificity. Mammalian Cut proteins may yet play another biological role, specifically in proliferating cells. The binding of Cut to a consensus binding site is found to vary during the cell cycle. Binding is virtually undetectable in G0 and early G1, but becomes very strong as cells reach S phase. This results both from an increase in Cut expression and dephosphorylation of the Cut homeodomain by the Cdc25A phosphatase. Cdc25A has been found to play a role in the G1-S transition. It becomes active in late G1, activated by the cdk2-cyclin E complex and blocks the inhibitory effect of p21 (See Drosophila Dacapo) on cyclin-cdk complexes. Microinjection of anti-Cdc25A antibodies in G1 cells is known to prevent progression into S phase, and Cdc25A expression is upregulated by c-Myc. Thus, Cdc25A plays an important role in the control of cell-cycle progression; however, apart from cdk2 and cdk4, its physiological targets have remained unknown. The increase in Cut activity coincides with a decrease in p21 mRNAs. In co-transfection experiments, Cut proteins repress p21 gene expression through binding to a sequence that overlaps the TATA box. Moreover, p21 expression is repressed equally well by either Cdc25A or Cut. Together, these results suggest a model by which Cdc25A activates the Cut repressor, which then downregulates transcription of p21 in S phase. Thus, in addition to their role during cellular differentiation, Cut proteins also serve as cell-cycle-dependent transcriptional factors in proliferating cells (Coqueret, 1998b). Previous experiments with peptide fusion proteins suggested that cyclin A/Cdk1 and Cdk2 might exhibit similar yet distinct phosphorylation specificities. Using a physiological substrate, CDP/Cux, this notion has been confirmed. Proteolytic processing of CDP/Cux by cathepsin L generates the CDP/Cux p110 isoform at the beginning of S phase. CDP/Cux p110 makes stable interactions with DNA during S phase but is inhibited in G2 following the phosphorylation of serine 1237 by cyclin A/Cdk1. It is proposed that differential phosphorylation by cyclin A/Cdk1 and cyclin A/Cdk2 enables CDP/Cux p110 to exert its function as a transcriptional regulator specifically during S phase. Like cyclin A/Cdk1, cyclin A/Cdk2 interacts efficiently with recombinant CDP/Cux proteins that contain the Cut homeodomain and an adjacent cyclin-binding motif (Cy). In contrast to cyclin A/Cdk1, however, cyclin A/Cdk2 does not efficiently phosphorylate CDP/Cux p110 on serine 1237 and does not inhibit its DNA binding activity in vitro. Accordingly, co-expression with cyclin A/Cdk2 in cells does not inhibit the DNA binding and transcriptional activities of CDP/Cux p110. To confirm that the sequence surrounding serine 1237 is responsible for the differential regulation by Cdk1 and Cdk2, four amino acids flanking the phosphorylation site were replaced to mimic a known Cdk2 phosphorylation site present in the Cdc6 protein. Both cyclin A/Cdk2 and Cdk1 efficiently phosphorylates the CDP/Cux(Cdc6) mutant and inhibits its DNA binding activity. Altogether these results help explain why the DNA binding activity of CDP/Cux p110 is maximal during S phase and decreases in G2 phase (Santaguida, 2005).Cut interactions as a transcriptional repressorThe CCAAT displacement protein/cut homolog (CDP/cut) is a divergent homeodomain protein that ishighly conserved through evolution and has properties of a potenttranscriptional repressor. CDP/cut contains threeconserved cut-repeat domains and a conserved homeobox,each involved in directing binding specificity to unique nucleotidesequence elements. Furthermore, CDP/cut may play a role as a structural component of chromatin through its direct interaction with nucleosomal DNA and association with nuclear matrix attachment regions. CDP/cut is cell-cycle regulated through interactions with Rb, p107, specific kinases and phosphatases directing the transcriptional activity of CDP/cut onsuch genes encoding p21WAF1,CIP1, c-myc,thymidine kinase, and histones. CDP/cut is associated with histone deacetylase activity and is associated with a corepressor complex throughinteractions with histone deacetylases. The interactionof CDP/cut with CBP and p300/CREB-bindingprotein-associated factor (PCAF) is reported along with the modification ofCDP/cut by the histone acetyltransferase PCAF.Acetylation of CDP/cut by PCAF is directed atconserved lysine residues near the homeodomain region and regulatesCDP/cut function. These observations are consistentwith the ability of CDP/cut to regulate genes as atranscriptional repressor, suggesting acetylation as a mechanism thatregulates CDP/cut function (Li, 2000). CCAAT displacement protein/cut homolog (CDP/cut) is a highly conserved homeodomain protein that contains three cut repeat sequences. CDP/cut interacts with a histone lysine methyltransferase (HKMT), G9a, in vivo and in vitro. The deletion of the cut repeats withi
