256x192 on Game Gear games. #402

Example: Castle of Illusion.

The game is using Master System resolution incorrectly. I've tried to force GameGear hardware on Core options, but it doesn't work.

The game should be run at 160 × 144

EDiT:Sorry, I misread your issue. That game is actually a Master System game put in a Game Gear cartridge and it runs on Game Gear in Master System compatibility mode, so its resolution is actually 256x192 like other Master System games. The Game Gear LCD screen does some downscaling/cropping so this fits on screen but this is not emulated as it makes the game blurry (see https://www.smspower.org/forums/9562-GameGearSMSModeVideoScaling) and there is no real interest reproducing it. That game is emulated as if it was displayed by Game Gear through the TV output.
