Oh well, i don't think it will run much faster

Tested it on my Falcon in both 030 and 060 modes, and I got the same result in both. The screen (VGA) is split around 1/3 from the top, the bottom part is all white and the top part is all purple and then goes all black. Then nothing more.
Tested with Sonic the Hedgehog.
My port is not exactly pretty. But it's very playable with joypads. The PSG is emulated using the YM-chip, because they're fairly similar. Periodic noise is approximated when possible, and the noise channel is simulated by using free channels or by enabling noise on some other channel with roughly the same volume. I have no idea where I have the files though

Can you post a ROM that you know works?

It could be that it is simply very slow and it's loading the game. For how long you let it run ?
I have attached another version that initialize the display differently. Give this one a try if it still doesn't work.Can you post a ROM that you know works?
This homebrew (a button test) works fine for me.
Let me know if this work so i can go ahead and release my game c: (somewhat done)
And i probably won't bother adding back sound support... it's too slow as it is right now.
Using the DSP is an even crazier idea ha

Captured from a Falcon ct60e 95Mhz VGA. I hope it helps you.

Is there any chance of a Sega megadrive emulator for a ct60 falcon? Damn that would be nice

From my non-coding perspective, I'm guessing an '060 class machine to run something like that at all...
Also somewhat hand-optimised to make it run half-decently.
