    New Build released ( Sonic Delta v0.50 ) / Hardware.

    The Following issues was fixed:
    - The screen goes black for a few frames when restarting a level underwater during Title Cards event;
    - The mappings (white flash) when Robotnik is hit in Final is wrong;
    - The palette used in background of Special Stage from Sonic 1, making the eyes of the birds and fishes looking strange;

    And these reported by AURORA☆FIELDS
    - " Some badniks palettes don't quite look right, there seems to be a green-ish color that isn't supposed to be visible";
    - "Entering and exiting Scrab Brain 3 causes visual glitches with the palette" (The Title Cards underwater issue fixed this).

    More bugs:
    1. The Sega chant is higher pitched (issue in regular Sonic 2 as well).
    2. The "S" monitor uses the title card graphics for its icon.
    3. Exiting a Sonic 1 level causes the foreground to become disjointed.
    4. Using Debug Mode in the Sonic 3 two player stages makes Sonic unable to exit.
    5. A large amount of Chrome Gadget's background details are missing thanks to the palette being too dark.
    6. Super Sonic has a full palette cycle that's never used, alongside a third frame for his idle animation (keep in mind that the full palette cycle was never completed, so duplicate the third last palette entry to replace the very last one).
    7. During the S&K ending sequence, the Master Emerald's graphics aren't loaded fast enough resulting in the title card graphics temporarily appearing.
    8. The Tornado text during the S&K ending is flipped.
    9. Perhaps there should be a cheat code to unlock the Super Emeralds?
    10. The Motobug's red shading seems to be reversed, and has a bit of green at the back.
    11. Rings can overlap with the title cards.
    12. Some of Super Sonic's sprites aren't aligned properly (especially his balancing sprite).

    This happens in vanilla S(3)&K, too (please excuse the noobish video, it was 14 years ago).
    This, too, happens in the vanilla game.

    Note that I'm not saying that these shouldn't be fixed if possible, but you shouldn't blame Esrael for them, either.

    Some of them are design choice or normal game behaviour.
    The game was not meant to be played through debug mode and related issues can be ignored.
    Some Sonic 1 Art was changed to fit in Sonic 3 engine.

    The Following changes / fixes was made:
    - Edited Art for Crabmeat and Motobug enemies used in Green Hill and Spring Yard;
    - Fixed an issue where, if you are on top of an ice cube in Icecap and Miles break the cube, you could get walking in the air;
    - Miles no longer is loaded for Sky Sanctuary in Knuckles and Miles mode, Miles appear with Tornado to rescue Knuckles. (Sonic still rescue Knuckles in Knuckles alone Mode);
    - Changed the Master Emerald art load to avoid visual issues in Ending Sequence;
    - Small change in ending sequence to show "SONIC" text in Tornado in normal reading order.

    That's what I said about Knuckles being Pink too much when Playing as Sonic/Tails, Sonic Alone and Tails Alone. This has to be fixed making him red.

    Bugs (these are also in standalone games):
    • Breaking a bunch of S monitors will destroy the game (first the background messes up, then you can't control Sonic, and sometimes the error handler will even popup or the game will just freeze).
    • The HUD numbers (both for Debug Mode and the lives icon) tend to look weird when certain palettes load.
    • Transforming twice within the same level messes up the fade-in (as the game is clearing the palette as a byte, not a word).
    • The camera jerks up a bit when Tails rolls.
    • When Tails gets hurt, he flashes but his tails don't.
    • The developers forgot to update some of Sonic's and Tails' sprites to give them black soles (also happens to Knuckles in Sonic 2 special stages).
    • The alignment for characters undersides in the Sonic 3K special stages are quite bad, and the shading is also pretty basic.
    • More of a nitpick, but the stage select shows the prototype Sonic 1 level order instead of the final (which is used in game).

    I really like the concept to play all Sonic levels from Sonic 1 to 3 & Knuckles. :)
    I didn't think from 25 years that this huge project would become reality.

    I tested this version in emulator and real hardware and worked fine.
    Note that the savestate from previous versions will not work in this version.
    Also, tell me specifically where you are having trouble to see if I can help.

    Working on my art!
    3 suggestions:

    - maybe make Eggman's glasses a consistent color between all three games
    - maybe change the color of Sonic 2's pink emerald, which in Sonic 3 onwards was swapped out for another color
    - the roulette bonus stage HUD has "RINGS" instead of "RING"

    Small bug I noticed: The graphics bug for the Casino Night roulette rings also happened to the rings that come out of the Flying Battery capsules (or perhaps a related, but different bug?), but the fix did not carry over.
