Regarding the trouble with Battle Garegga, h.active 320 works in all of these modes:

2x 256×240 (horizontal multiplier: 3x)
4x 512×240 (horizontal multiplier: 2x)
4x 320×240 (horizontal multiplier: 4x)
4x 256×240 (horizontal multiplier: 5x)
5x 320×240 (horizontal multiplier: 5x) <– unstable with samplerate above 422
5x Generic

I don’t see why h.active 320 works in 2x 256×240 and doesn’t work in 5x 512×240 since both have horizontal multiplier 3x.

I also don’t see why the image becomes unstable above samplerate 422 in 5x 320×240 and works fine at the correct samplerate 432 in 4x 256×240 since both have horizontal multiplier 5x.

I’m trying to get Raiden to work too. The only samplerates that make sense to me there are these:

( 20000000 / 2 ) / ( 258 × 60.49 ) = 640
( 20000000 / 3 ) / ( 258 × 60.49 ) = 427
( 20000000 / 4 ) / ( 258 × 60.49 ) = 320

But I can see some blinking and out of place pixels in all three samplerates at every sampling phase setting. What am I missing?
