There seems to be something wrong on the right-hand side.

Test rom: https://github.com/PeterLemon/SNES/tree/master/PPU/HDMA/HiColor64PerTileRowPseudoHiRes

Thanks for the reports!

The SPC test rom fails because cubic interpolation is turned on (I accidentally made the option default to being enabled when I added it - it defaults to disabled now) - you can disable it in Audio->Advanced and it should fix the test.

The HDMA test was a small bug with color math when using high res mode and also reading/writing PPU registers in the middle of the scanline (unsure if any commercial game actually does this specific combination anywhere) - should be fixed now, too.

Wow, that happened quickly. You're welcome! :)
