AFAIK there are no gaps in CD address range, it's mirrored all over the place as upper address lines are simply not connected to expansion port..

It's controlled by /CART (B32) pin on the cart connector only, if it's connected to ground, cart's /CE (chip enable) signal will respond to 000000-3fffff, else to 400000-7fffff.

Yeah it's interesting boot mode where you can avoid having to start the CD/bios yourself and have it done for you, I guess?

Looks like a MESS bug to me, have you tried a different emulator?

I've got someone to translate Japanese text as

When G/A is powered on and reset, the input indicator is activated.

So I suppose this means it is power on reset signal.
Still strange it's marked as I/O in MD2 service manual and not just output.

FWIW it's working in PicoDrive too. Doesn't latest Kega do it too?

So, has anyone played with FRES?
I've noticed pressing reset on MD doesn't reset gate array registers at all, actually even the bios on slave still seems to be active and I can communicate with it from a test program on cart.

I don't think I'll release this one as-is. There are too many hacked up copies of Gens floating around, and too many other hacks in my build. However, I'd be very happy to port GDB support into another emulator should there be an opening of source... Feature like that would certainly be welcome in ...

Just edit your .brm file with a hex editor, throw in some FFs or something.

Nice card, no Linux drivers though

Just out of interest, as it's says it's RGB capture, how was it made? Is that using some hardware that TmEE is credited with?

Really impressive stuff, congrats with a great release!

Emulating this on 200MHz ARM will be a challenge, but I take it. I'll be back to you when I'm done, if you care (and still alive).

If you look at the code, it copies the register to RAM for later use.

You can change from: to just .. and then fix checksum.

Well I'm looking for mode1 + 32x, so it's Wolf32X only then. The Wolf32X release thread (first post at least) doesn't seem to mention mode1 though.

I'm not aware of any emulator yet supporting the CD mode 1 in 32X mode. I had to get that working completely on real hardware via flash cart. Fusion supports mode 1 in MD mode. A bit of a gravedig, but I wonder if we have anything that uses this? I could of course cook something myself, but maybe s...
