Every GG game that runs in Master System Compatibility Mode I tested (and own a copy of) does not work correctly:

  • Mikey Mouse Castle of Illusion (J) / (US/EU)
  • Predator 2
  • Prince of Persia

Looks like color palette and resolution are off.
All work fine as physical copy with the GG adapter tho.

I can confirm this issue.
SMS compatibility mode is definitely broken on the core.

Confirming this even with the latest versions of Analogue OS. It looks like the core cannot handle straight SMS conversions and displays palettes weird.
