Hello,
This port looks great but I can't play it as when I press button A, I immediately get a glitchy white screen in both Arcade and Home modes.
My setup: PAL Megadrive with NTSC 60 Hz mod, official 6-button controller, Mega Everdrive Pro with 26.0625 firmware.
Edit: Just updated firmware to the latest version (v26.0925) but the glitch is still there.
