...Of course, I'm not gonna spend all those code waiting for the HBlank.
I'm trying to make the scroll look like a wave. Assume that the first page and the second page are exactly the same.
The following code is my code, and some graphical glitches appear at the right edge of the screen when running on FCEUX.
;note that IRQControl is #$03
BEQ I_CW6_0_1 ;First IRQ
BEQ UsualIRQ ;Last IRQ
;IRQLatch or IRQControl doesn't need to be changed
ADC IRQWaveDif, Y
;ADC IRQWavePageDif, Y
If the commented code are turned into actual code, there are more graphical glitches.
