vrc4 counter updated to cpu cycle accuracy - is it any better
vrc7 counter modified the same way - it isn't really better
vrc6 counter modified to match the others, doesn't really look different
notes on what works better/ worse with vrc irq changes
Fixed the sound test in Lagrange Point not working until the game was reset at least once. The sound chip should probably be initialized when it is written to, not when the scanline counter clocks the first time.
