Emulator

Hi guys, posting this here couse in main forum there isn't activity.
So, straight to the point:

At the begining of the file, line 29, it apperas the following code:

u16 memory = (u16)g_dspInitialize.pGetMemoryPointer(_Addr);

and so on on line 48. I was searching about trying to fix mario galaxy bgm, but i found on the docs that the game use dma version, wich is exactly teh game uses, i.e, pGetMemoryPointer. after all this, i think there must be some kind of iIFDEF function, to make the case if is dma version or something else, couse i think is making conflict with accelerator on line 145 and so on, on finish-up loop and main render loop on RenderVoice_PCM16. Correct me if i'm wrong plz, to search for another side. greets
