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...

Re: Interest in Dynarec?

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 ...

There is ! by the way, how you figured this code ? where did you got the documentations ? In gens, my only way to implement multipad support was reverse engineering from 4-players game... Héhé, its a long story :) I had a .txt documentation, so i coded a SegaMultitap code (which wasn't working exep...

All extern does is tells the compiler that the symbol being referenced is in some other object file (not in the current code being compiled) and therefore the reference should be resolved at link time. Just sticking those two lines in your source won't cause the binary file to get included in your f...

In fact i convert them to C file because i need an identifier to reference the binary data. It's possible to link binary file to your C project with the linker, but then, how you can reference them in your C code ? objcopy automatically creates start and end symbols when you turn a raw binary into ...

AFAIK, even when the DMA engine is set to completely take over the bus, the CPU can still execute code out of cache.

According to this FAQ, it was never released even in Japan: http://www.classicgaming.com/museum/faqs/megadfaq.shtml Given how infrequently it's mentioned compared to the Meganet Modem (which is quite obscure), I suspect it was indeed cancelled before release. Anyway, last I checked the Saturn keyboa...

The mouse was released and I own one, but AFAIK a keyboard wasn't. They may have developed a prototype, but it was never available for sale.

Hmm, I like the idea. I've actually been considering the possibility of a SCUMM-style system for Sega CD - would this be something similar, or would it be more low-level? I'm not familiar enough with SCUMM to say and for that matter I'm not even sure what the final product will look like at this po...

AFAIK, the Saturn PS/2 keyboard adapter should be electrically compatible with the Genesis. I started hacking a DB-9 connector onto one, but never finished.

About the ram bus, i always thought it was full 32bit... I still think it is, else, why would the cartridge access be 3-4 times slower? I believe access to the cartridge is split evenly betweenthe 68K and the 32X with the 32X getting one access per 68K bus cycle. The SH-2s run at 3 times the clock ...

Presumably because he doesn't have a flash cart, but does have a Sega CD.
