The Slim error is a firmware/model check, so in PPSSPP try setting PSP Model to PSP-2000 and Firmware Version to 3.71 M33 if that option is listed, then retry the Slim build. The Phat build crashing after ROM selection is more likely a compatibility or ROM issue; try a different MVSPSP build and verify the ROM set. The Windows 11 part is separate.
