    Looking at the demos, the character distribution seems rather lopsided, giving Tails and Knuckles only one demo each. I don't know what the limits are for demos (if any), but a concept I had was to have Tails in all the Sonic 2 zone demos, Knuckles in all the Sonic & Knuckles zone demos, and the Sonic 3 zone demos get split evenly across all characters. Sonic would retain all the Sonic 1 zone demos, and I expect a few more demos would have to be recorded to even things out more since Sonic 3 and S&K get 3 demos each plus the special stage demo, while Sonic 1 and 2 each only get 2. In regards to the special stage, perhaps a demo of an S1 special stage as Sonic and an S2 special stage demo as Tails (while changing the Blue Spheres demo to Knuckles) would be nice. Additionally, it'd be a nice touch if the Bridge Zone demo was Sonic alone, instead of Sonic & Tails.

    Lastly, a really minor nitpick: the Angel Island demo still uses the Super transformation cutscene at the beginning of the level instead of the custom surfing cutscene that's seen in actual gameplay.

    It's no mystery that I'm an 8-bit fan, so I'm happy to see Bridge Zone, and I made a video of it:


    It has a few collision issues, though, especially noticeable in the second act.

    Also, I like the music, but isn't it the one converted by Puto and me a few years ago? If it is, I am happy and actually flattered that it's been featured in such a fantastic hack.

    Thanks. Yes, there are two sounds that was made by Puto in Sonic Delta (Bridge and Labyrinth). I have some issues to get the Bridge sound working, but get it correctly in latest version.
    And now knowing that you have participation I will give the proper credits in official hack page and SHC2021 credits section. And I have a plan to add a credits screen in the hack, so the people get the proper credits.

    Oh, I wasn't begging for credit, believe me, I was honestly happy and surprised to see this old conversion ending up in such a great hack :)

    In fact, if you like any other songs I converted, feel free to use them all without the need to ask :)

    New Build released ( Sonic Delta v0.69 ) / Hardware.
    (Everdrive X series users can get a custom O.S. in the hack page to enable support to hack (SRAM and SEGA Mapper enabled)).

    Terraonion released a firmware update enabling full Sega Mapper and now Sonic Delta 40Mb is fully supported on Mega SD device.

    - Fixed energy ball launcher position in "Final" (S1);
    - Fixed energy ball colours in "Final" (S1);
    - Fixed final Casino Night sound in "Sound Test";

    And
    - Added credits screen, that can be acessed through Options Menu.

    Best regards:

    Two visual Tails-related bugs here.

    Dr. Robotnik on the signpost uses part of Tails's palette for the orange part of his shirt; as a result, Super Tails causes that part of the signpost to pulsate in color along with Tails. This could be part of base S3&K, but it's impossible to see because of how signposts & Super transformations work in that game. Not sure how feasible it would be to fix this, given the game's limited palettes.

    Tails's tails are misplaced in his mid-speed running animation (tails are twirling in a circle, but not the super high speed animation where they're fully blurred) when his sprite is rotated. This is definitely a bug carried over from S3&K.

    The Super Tails palette is from base S3K. It's easiest to see in the Lava Reef boss fight, since Eggman stays still for long periods of time and the Super Flickies don't hurt him.

  10. I’m 6 years late but I heard about this through YouTube and decided to try it out for myself.. so far I’ve played through the first 3 zones of the Sonic 1 portion and it seems more fluid than the original.. I’m playing the latest v 0.69 version

    I’ve read up that this game features quite a bunch of scrapped content and zones from Sonic 2 (obviously since that’s what the original hack was based on) Forgive me if this has been asked but has it ever been considered to include scrapped content from the Sonic 1 and Sonic 3 prototypes? (UFOs, Sparkling Zone background, old Angel Island and Hydro City backgrounds, etc) Or would it be too much for the ROM to handle?

    EDIT: I’ve played up until Oil Ocean and the only bug I’ve noticed so far is with the speed shoes.. Sonic goes fast but the music does not speed up.. I had this happen to me at Winter Hill and Casino Night

    What would cause the framerate on the Options screen to change depending on what track you have highlighted in the Sound Test? Check the scrolling between when you have a short name like "Wood" vs. something like "PC Carnival Night 2" showing.
     
  12. I think it has something to do with the bank-switching that the game does, Sonic 1/2 levels are in a different spot in the game’s memory than the S3K levels, that and the S3K portion uses a separate sound driver from the Sonic 1 and 2 portion, so it might be a side effect of the game switching between sound drivers.

    (EDIT: I think I might’ve misread the question...my bad. lol)

    This is because the draw text routines are unoptimized and take a lot of cpu cycles ( I did not notice this until read your comment). This is not hard to fix.
    The only thing that cannot be changed is the short pause that occurs when you play a song that require the Sound Driver change.
