    Hi all

    I'm using a Retroarch nightly build from a few days ago. The version string shows "1.3.0 - CATSFC(SNES9x) v1.36)". It's installed as a CIA on a 10.4 emunand on a EUR n3DS. Donkey Kong Country plays at full speed and performance during levels is perfect. But on maps and boss stages theres a weird flashing black or white effect on the screen. I've attached a video to show the issue. I would appreciate any ideas about what's causing this and how I can fix it!

    I've had a similar graphical glitch in Super Metroid. I ended up using pocketsnes and it went away so I just stuck with pocketsnes. And it works just as well in my opinion :)

    It worked! The pocketsnes core still runs the game at full speed but without the graphical glitches. Thanks buddy!

    Catsfc plus also fixes this glitching. Perhaps it's relates to spc timing?

    This bug has been in catsfc for months now. I had it too when running DKC1 (pal). Because I didn't want to lose progress by starting over again in pocketsnes, I kept trying out different settings to see if I could fix it. Turns out setting a video filter in options will fix it. I'm now using the EPX filter I believe, it doesn't seem to slow down gameplay (some others do).

    Thank you, I'll try it. However, it's easy to avoid losing progress when switching cores. You just have to change the locate where the emulator looks for the SRAM files.
