    These are the original specs of the CPU:
    - Samsung S3C2400X01 (ARM920T core)
    - software chosen speed (safe speed: 20MHz to 133MHz, overclock to SDRAM limit: 160MHz, overclock to CPU limit: 186MHz)
    - 16KB Data-cache, 16KB Instruction-cache

    Some GP32s are able to maintain high speeds better than others. I think you could emulate a GP32 clocked at lower speeds, like 66Mhz. From what I hear, that is the default clock speed too, although that could vary by firmware revision. Most of the stuff that uses higher speeds is probably stuff that should be ported anyway, like emulators. BlackAura, do you know how complicated the video hardware is? Could you use hardware acceleration like you do with Genesis Plus? I'm not asking you to attempt that, I'm just curious.

    It doesn't look like it even has any video hardware. It seems to be a simple linear framebuffer. If the game doesn't play with the video registers in the middle of a frame, you could probably just copy the framebuffer to the Dreamcast video RAM, and that'd be it.

    Instead of proper emulation could it be simulated. (dont kill me if that's stupid)
