Thanks very much for the quick reply.
I’ve just tried the 32x hacks, but I can only seem to get it to appear as an individual System, not under 32x. When importing, I called the system “Sega 32x Hacks”, scraped as Sega 32x, and chose RetroArch as the emulator. It just comes up like the attached.
I’ve right clicked on it, selected edit, and saw that Scrape as was blank, I’ve set it to Sega 32x, but it hasn’t made a difference. Am I missing something?
