I tried it today, and that works surprisingly well. Not ideal, of course (as I understand, author did not optimize code for PPC) - with noticeable but acceptable frameskip, and with good sound, at least. Unfortunately, this emulator not shows FPS, and I was not able to edit config file at device wh...

Try for example Flashback bgm3 in sound test, actually only Kega with HQ mode activated could handle this correctly... even Gens with FM Interpolation ON sound weird on this one. Do you know what might cause such harsh blips ? bad frequency calculations, unacurrate sampling ... ? I don't know exact...

The problem with using C/C++ vs assembly is register usage. For best speed, you need to keep certain things in registers as much as possible as the memory is SLOW (as you mentioned yourself). With C/C++ emulators, the emulated stated is always in memory. Because of this, I've yet to see a C/C++ emu...

In case of small devices like today's PDA's, smartphones, and current-gen handhelds, assembler is not solution. These devices often has relatively fast RISC CPU's (like ARM) with really slow memory. So, it's comes very hard to make hand-written code works faster than today's optimizing C compilers ...

The majority of the backgrounds run at 15FPS, while the ships involved in actual gameplay are running at or over 30FPS. Level 10 though, the earth level, runs between 5-7 FPS. I also think that it was level 10 that they were referring to having 500,000 polygons per second in, but at 5FPS on average...

I think most people only had a look at the first pages and thought it was exactly like sega2.doc in fact, I initially thought the same thing, but was recently wondering why there wasn't any infos about sprites pattern in sega2.doc and remembered about this scanned doc :wink: by the way, the appendu...
