I can give you help with the 32X CD boot process if you need it. It's different than with a 32X cartridge game and I'm not sure if there's appropriate documentation floating around for the 32X/CD combo.

How does these light guns work ? I'll pull the trigger, INT2 happens, then soft reads the gun status (if gun sees the beam, it has some signal high) then according to H and V raster pos, it determines if an target needs to be destroyed or not ? INT2 doesn't happen when you pull the trigger. INT2 ha...

Well to be fair, this probably doesn't have the cache coherency problems the 32X has. It's also considerably faster: 480 MIPS at 200MHz and has an FPU.

I don't think the bot figured it out. I think the bot ran through a suite of common tests which all failed. The owner of the bot then came along, noticed that your captcha doesn't change and modified his bot to handle your site. Alternatively the bot could just be running a dictionary attack on the ...

OPL and OPN is a different FM synth chips series. They not directly compatible, and has different set of synth abilities. Main difference: OPN always was 4-op with one osc. waveform (sine); OPL was 2-op (with 4-op modes) and selectable osc. waveforms. then shouldn't that mean that i should be able ...

i think im going to have to take up a book on 68k assembly... Well, C is an option as well. If you want to stick with assembly, I have a beginner's guide as well. See the tutorials on my Sega CD page (http://www.retrodev.com/segacd.html). They don't get into anything Genesis or Sega CD specific tho...

i don't think the intel 8086 could either, but they did have subroutines ;) I don't think subroutines are exactly what you're looking for here. A subroutine lets you make a commonly used piece of code re-usable, but it doesn't allow multiple things to occur at the same time. Anyway, in most BASIC l...

It's probably not padded to a sector boundary (i.e. the size isn't an integer multiple of 2048 bytes). Just add extra bytes to the end until it's a nice even multiple of 2048. That said you might be able to accomplish what you desire using SLO assuming BasiEgaXorz has some kind of command to poke va...

I seem to remember that branches are relatively expensive on the SH-2 even with the delay slot instruction. Still, 95,869 * 60 fps * 2 instructions = 11.5 MIPS which means an average of ~2 cycles per instruction. You can do better than that if you keep your branching to a minimum and avoid pipeline ...

There's one thing I have to say about this whole idea: Quake 32X CD. The lack of RAM in the 32X and the inability of the SH-2s to access any of the Sega CD's extra RAM is going to make any decent 3D game on the 32X CD combo difficult without extra hardware. This is not to say that it's impossible (...

So I take it this is more or less performance per frame/field rather than per second?

Any chance you could make the source available? I should be able to test it using my Sega CD and transfer cable if you do.

haha, that's insane ^^... "static compilation ?" Ho yeah :D Static Recompilation :) But isn't static recompilation similar to dynarec? It is maybe even more handy? I really get the recompilation thing but I don't get the advantage of doing it dynamicaly... The problem is that it's very difficult to...

I'm thinking about trying to write a dynarec targetting 68K CPUs (the dynarec would run on the 68K not emulate it). Is there any interest in such a project and if so what CPU would you like to see emulated? I'm thinking about trying the 6502 since it has such a simple instruction set, but I'm open ...
