New NullDC Emulator WIP Update

Some WIP news and a clarification from drk||Raziel about the port of the Dreamcast emulator NullDC for the PSP, let’s see what he had to say shall we?

nullDC/PSP update #2++

So yeah, some fixes here and there, gdrom code added, gdrom selection and ..

Too bad the game crashes with some invalid stuff on TA ingame … i realy need to use *stable* versions while porting, and not experimental drkpvr stuff :p

PS. Oh yeah, the game is DOA2LE

*edit*

Aparently SOTB works fine too

*edit #2*

Fixed the ta problems, doa2le ingame works

Clarifications about nullDC/psp

nullDC/psp will only be for psp lite. The old(’fat’) psp just doesn’t have the ram space needed, nothing i can do about that.

The current speeds are very low, but that is expected. There is no dynarec, no optimisation, not even a single mips assembly line on the current source. Most of the current code (everything, apart from 3d rendering) is based on the pc version of nullDC, and most of this code will be replaced. So yeah, IT WILL TAKE QUITE SOME TIME BEFORE THE PROJECT IS ANYTHING NEAR USABLE.

The current speed (as stated by the on screen counters) is around 10%. THIS IS WRONG, IT IS ACTUALLY LOWER. The interpreter runs underclocked (to make the speed bearable). This also happens on the pc build of nullDC when using interpreter (for the same reasons). The rps field (renders per second) is accurate.

After the code is cleaned up/rewritten there are plans to port to pandora ( www.openpandora.org, really cool stuff ) and possibly other consoles (wii seems like a nice target, ps3 if there’s a way to get 3D access). ALL THIS MAY(OR MAY NOT) COME AFTER THE CODE IS REWRITTEN, SO DON’T ASK ABOUT IT NOW(you’ll just waste your time, really). The code will be open sourced as soon as it gets stable.

While i think it is possible to get fullspeed on psp it is quite likely that i will be proven wrong. I CAN NOT MAKE ANY PROMISES ABOUT THE SPEED, I ONLY PROMISE I WILL TRY TO GET IT FAST.

If you somehow think this project is wasted time, then don’t waste any more commenting/thinking about it. My time is .. mine, i can do whatever i want with it. Seriously, if you want to say something bad just save your time, it wont really change anything ;).

There, i hope this clears up some things. If for some reason you’re still confused read over the bold parts, that will help :p
