Experimental patches
1- gpu.c
We don't emulate bus conflicts. Especially with DMA.
Lower vram2mem, mem2vram times (1 -> 0.25)
- fixes X-Files videos
2- cdrom.c
Duke Nukem - Time to Kill uses CD attenuation values for XA music, speech
- fix volume slider
3- cdrom.c
Add cdrom dma wrapping
- possible Ape Escape additional fixes (>2352 transfers in several places)
All disabled - view diff and activate at your own risk (accuracy regressions)
