People should also state what device they are using:
- Raiden II and also Raiden DX plays smooth with sound
- Gunners Heaven same as above
- Dead or Alive plays slow with sound and "tolerable" without
- Crash Racing same as Dead or Alive, but some car models only show the wheels
- Hot Shots Golf plays smooth with sound
I also have a PSX emu on my N900 and games play better on it, due to more graphic tweak options and the keyboard. My N900 uses same chipset as Droid and overclocked to 800mhz.
BTW, a LOT more games will play smooth if or when hardware acceleration is added. N900 is not accelerated either.
