Hey! Not been working on it much lately :( The plan is still to try to burn some ROMS with what I running in MAME and try to run that on a real System32. I've been doing some work on some tools though. Tile editor and sprite editor, but I think I need that test on real HW to really get going...

@Fluffy: Cool.. never heard about Tiled before. Looks cool. I'm already too far with my own solution so I'm gonna go with that - but yeah probably a lot of overlap :) Ok, got a sprite on screen now. I also got some PCM audio working. It was quite fun doing some Z80 stuff again - that's the CPU...

Update! Dived into the tile hardware a bit more. Figured out most I need to know right now. I was really confused about the palette organization - it's super weird. The tile index and the palette index is actually the same index! That will probably cause some headaches on the tooling front...

Hehe.. There might be a bit more docs on Naomi. At least I hope so :) I have a special place in my heart for Dreamcast so that naturally extends to Naomi! Sounds cool!

Hi! I got a little further. Had some problems with MAME crashing after running my code for a few frames. Tried to compile MAME with Visual Studio to be able to track the crash so I could get an idea of what was wrong. That was harder than expected. MAME is so big that my machine ran out of...

It does have a plain frame buffer, but it's a bit weird as far as I can see.. there is not enough memory to double buffer so animating stuff will be difficult..

A small status update for you all! Since I've got an assembler from elsewhere I saved a lot of time so I've basically done step 1-5 done now! I just got hack-rom working running some simple code! Now I need to do a little more setup code - ex interrupts etc. I've looked at a couple of games...

@brizzo oh wow! NEC V60 support was added earlier this year! Crazy. Looks good. Found some small issues but was able to fix them a little. Reaching out to the author to get things fixed proper. Will be checking unidasm out for sure. I played around with the MAME debugger the other day and it's...

Yeah this is good stuff! Thanks! Think I've seen it before many years ago, but was just unable to find it again :-/ I'll start reading :)

Yeah I've been wondering about an LLVM backend too.. I've always wanted to something with LLVM - maybe now is the time :) The key for good code on the V60 is to utilize all the funky addressing modes I think. How that is done could be quite interesting actually.

Hi! Thanks @ekorz - some interesting tidbits in that MAME link. I've already dived into V60 docs - quite an interesting CPU I must say. When @Toonz first talked about going for System32 I thought it was just another 68000-based machine :) Would have been a lot easier though since there are...

Hi! I've been thinking about trying to do some homebrew on System 32 together with a friend of mine (Hi @Toonz ! :) I'm trying to find as much documentation about the hardware as possible, but it seems there is not much around. Does anyone know where to find more info? Right now, it seems my...
