Is anybody using Groovymame for PC-Engine Emulation?
I have very bad tearing effects for all vertical scrolling games, e.g. 1943 or Galaga 88.
This only seems to happen in the PC-Engine driver "pce".
Everything is fine with the arcade or snes drivers.
I have tried to change frame_delay and vsync_offset in pce.ini. But nothing seems to help.
