    now, because I don't like to bother people. I went ahead to make a YT Video showing bugs that are known this time in development.
    also saves me writing an entire paragraph. The 1st and the 3rd bugs I need help with.

    for the final thing, it is probably the sound effect making the game crash

    yea true but when i disable the sound affect, it then affects the speed and momentum in the water and there's still a chance of the game crashing.

    1. Looks like it's just using incorrect mappings data? I have no idea how you have your splash screen set up, so I can't really tell you exactly what's going on.
    3. Did you by chance remove the H-INT trickery (all the stuff dealt with near Demo_Time and loc_119E)? If so, from what I'm seeing nowadays, it's advised against, according to the Sonic 2 installation guide anyways.

    Other than that, I went ahead and installed the driver on my end, and I had no issues come about.

    I will check that tomorrow.
    Also it’s actually no the incorrect mappings data because I tried different sizes in SonMapEd then used the tool Flex 2 as it shows in the video so I actually don’t know what’s going on there. Also the installation guide for the sound driver for sonic 1 didn’t include the advisement, but in sonic 2 it is?
    Odd

    Art not loading properly then? Bad base tile ID in the object you're using to display it?

    Probably the tile ID issue because the mappings where fine in SonMapEd but the same size.

    I've checked and there is a H-int trickery in my disassembly, however disabling it kind of fixes it, this causes the game not to draw the level layout properly and the water palate becomes buggy but does fix the crash which is odd? here's the disassembly's code (I commented out the H-int part)

    EDIT: I Fixed it, FINALLY.

    Another Question: idk why I have to ask so many questions :/
    anyway, the question is, you know the static look like the Mega CD (Sega CD for the Americans) BIOS Before opening a game.
    would it be possible in a rom hack on the mega drive *just a static image*
    this concept was brought up in Sonic 1 Remastered V2 rom hack.

    The function in the GitHub disassembly is called "TilemapToVRAM".

    yes I did realize that but then a roadblock hit me in the face.
    the mappings gets corrupted and spits out random tiles and with the tiles not showing the actual sprites for it but rather the SSRG Screen instead so it's a no go for me.
    So I just disabled it. But if I Will come back to the code I might be able to fix the issue but only people can tell I suppose :/

    Well, how did you port over the code? It's possible there's another mistake you made that's not being caught.

    I ported over the code by taking the unrecognized code and changing its instructions to the used ones like WaitForVBla.

    Well, what lines did you change? You're gonna have to be specific, because I cannot derive any info from generalized statements like that.
