Just go my Super NT. Loving it! I also have a modded Super Famicom with a SuperCIC mod.
One limitation of the Super NT is that it doesn't detect the region automatically like the SuperCIC mod does. Kevtris, I suppose you're already implementing the CIC lock. Would it be possible to automatically switch PAL vs NTSC based on the cartridge?
Even better: if SuperCIC pair mode could be implemented, then with a SD2SNES, the console could automatically switch between PAL/NTSC based on the region of the game.
