Emulator runs too fast #43

Closed MackW closed 10 months ago

MackW commented 10 months ago

Emulator seems to run too fast on speed x1 (might be NTSC vs PAL) not sure if it's the emulator or the VBL on port $FD (which is what it's synced on for speed) This is noticed by my demo RFDV7.rom when the music etc is playing. I'll write a little timing loop to check the frame length and will add details here

VBLANK is 60hz on NTSC and 50hz on PAL so NTSC will run fast.

MackW commented 10 months ago

Doesn't seem any way to change to 50hz though?

fvdhoef commented 10 months ago

The Aq+ is a 60Hz only system, since we're outputting to VGA.

Bahh,,, lol.
Will need to put timing detection code in then, Ah well good to know for future, so that I can make stuff compatible Can close this then
