That's pretty cool. I also did some Forth stuff for the Megadrive a long time a ago. But I used cross-compilation rather than interpretation (I had written a Forth compiler that could generate M68k assembly, which I then assembled and linked with the GNU binutils).

Which section(s) handles setting up the slave SH2?

You'll find the entrypoint in the crt0 (sh2_crt0.s in case of the gameboy emulator, and crt0.s for the other two examples I linked to).
The actual slave "main" function is located in slave.s or hw_32x.c.

I thought that writing 0 to the frame buffers didn't do anything? Bytes don't, but he's writing words. Any idea what the overwrite region would be useful for? IIRC, zero-bytes are ignored even when writing 16-bit quantities to the overwrite region. About that 256 byte section at the start of the fr...

http://jiggawatt.org/badc0de/NSF32X.png I've put in a bit more work on the NSF player I started writing late last year, so it's now at a point where it's working quite well. All of the emulation takes place on the slave SH2, and is done almost entirely in C (there are a few small portions of inline...

Always nice to see some new games. This one reminds me of one of the mini-games from "Chibi Maruko-chan : Mezase! Minami no Island!!" for the SNES:

Isn't there something you want to do for MD or SCD ?

I don't have a MegaCD, so that takes care of that

As for the MD; maybe, but not right now.

I released an updated version earlier this week. There's improved emulation, an updated UI, and more songs:

Tried this out on my Megadrive the other day. Really cool for an FPS running on the MD (even if you can't actually shoot the enemies yet).

I've released an updated version of my YM player, which now includes multiple songs and a TOS/GEM-inspired UI:

Another update, this time with some bugfixes and UI additions:

I've also released the source code.

Nope. I don't think he's posted on any of the forums I'm a member of since late September.

Alright, here's the multi-song version:

While I was at it, I modified the mixing a bit. I now output 24 kHz mono instead of 22.05 kHz stereo (the SID chip doesn't have any left/right balance anyway). And the output is no longer super-loud.

I'm planning to make a music disk out of this. It's mostly done, except that I need to create graphics for UI. Hopefully I'll find time for that in the next few weeks.

Here's another small project of mine. I've taken a SID player I wrote a few months back and ported it to the 32X: ROM download YouTube video (the video turned out a bit loud, so I recommend not watching it on full volume) Pretty much everything is done on the slave SH2: it emulates both the 6510 and...

If there is such a thing as a hell, I'd imagine it as having to sit in a badly ventilated room and write GCC-style inline x86 assembly in AT&T syntax all day, while two other persons are standing behind you having a loud and completely unrelated discussion; occasionally peering over your shoulder an...
