Here is a new video. Now, games I've tested so far work... but with some display issues.

My implementation supports Z80 access to the 68000 RAM. Apparently it doesn't work on all Genesis revisions. For a pin-to-pin replacement of the VDP, well, it's not even close, as I had to cope with the board's constraints (i.e use SRAM instead of DRAM), and also TG68 core constraints (it doesn't ou...

For the moment, there is no sound : nothing about the YM2612, and I've only written the timers of the PSG, as it seems that this is the only part that may cause issues with the the Z80 code, if it was missing. The TG68 core had a small issue with the MOVEM instruction, now fixed (I've contacted the ...

SEGA Genesis/Megadrive clone in a FPGA
I've been working on this for some months now, and I'm glad to have the first significant results today. See the (crappy) video here : http://www.youtube.com/watch?v=tOXrv4ubEbY It is based on : - the TG68 core from Tobias Gubener. - the T80 core from Daniel Wellner. - glue logic and VDP core from m...

Z80 clocking
Hi, I'm currently thinking about a possible hardware emulation of the Genesis in a FPGA. I'm only at a stage where I want to gather as much information as possible, and I'm somewhat struggling with some hardware restrictions of the board I'm using. So here is my question : from you experience, what ...
