    I remember a fellow forum was talking about how the screen stretch isn't working for H32 games. Can't seem to find that post anymore. I just wanted to ask a quick question: Does anyone know if the Sega Genesis has games that ever utilized both H32 (256x224) / H40 (320x224) resolutions in a single frame?

    Yes. One example is Golden Axe.

    Nice. Thanks. Am trying to see if I could shortcut the thing by assuming it's always H32/H40 per frame. Looks like I can't now. :)

    I just tried Golden Axe. It runs H32 in the title, and H40 in-game. But does it have both modes in a single frame? Is there a particular level or screen that does that?

    Oh, both in a single frame? Nope, not possible.

    Hi guys, I'm releasing a quick beta 3dsx version for anyone who wishes to test.

    You can download from below.


    Edit: Clicked "Post" too quickly. Forgot to add the change log:

    v0.92b
    - Support for Mega CD. You can actually play Sonic CD on O3DS (but setting frameskip to 1 to 2). It's choppy due to the skipped frames, but playable if you can tolerate that.
    - Very minor optimizations and bug fixes for YM2612 FM emulation
    - Now saves SRAM
    - Sound generation lag resolved (but I'll need someone to tell me if it really sounds better)
    - Default frame rate for multi-region games to 60FPS
    - Added option to force frame rate to 60/50 FPS
    - Fixed screen stretch for H32/H40 games.
    - Added more screen stretch options for PAL aspect ratio.
    - 6 button support
    - And some minor stuff here and there that I forgot. :)

    Oh good point, haha, forgot to mention that. It should be inside
    /3ds/picodrive_3ds/bios/

    The valid US BIOS file names are:
    "us_scd2_9306.bin",
    "SegaCDBIOS9303.bin",
    "us_scd1_9210.bin",
    "bios_CD_U.bin"

    EU BIOS file names:
    "eu_mcd2_9306.bin",
    "eu_mcd2_9303.bin",
    "eu_mcd1_9210.bin",
    "bios_CD_E.bin"

    JP BIOS file names:
    "jp_mcd2_921222.bin",
    "jp_mcd1_9112.bin",
    "jp_mcd1_9111.bin",
    "bios_CD_J.bin"


    If you can't find the BIOS with those file names, you can simply just rename it to any one of the 4 filenames that matches the BIOS's region.

    Just wanted to add that CD games will probably work better on the N3DS. :)

    @bubble2k16 it actually works pretty good on my end, if you set it to no frame skipping, it plays smoothly, but the audio lags, but i noticed if you load another game while in the emulator, it crashes back to the 3ds menu

    Popful mail works really well
