/vr/ - Retro Games

Fellow handheld gaming niggas, I already have dsixl (amazing screen) for ds and gba library, but I was thinking of getting a used psp for ps1/psp library and maybe better snes/gba emulation. Should I get psp (preferably 3000) or ps vita? Is it worth it? I don't want it to be too big or stick out due to thumbsticks in vita, but maybe more games will be worth it
From what I understand if I hack vita it will be 100% backwards compatible with psp and ps1 games? And psp will be 100% compatible with psp game roms and ps1 games if I do CFW?
