I have an old assassins creed psp 3001 that needs a new screen, battery, and shell. I'm thinking of restoring it so I can emulate retro games from ps1, psp, n64, Gameboy and whatever else It'll let me play. Aside from sentimental value, I'll like to restore it because it's as big as my Samsung galaxy s20 . I can just put it in my pocket and whip it out at work discreetly.. something I can't do with my steamdeck. However all those parts I need is adding up to $80

Are there any emulators handheld consoles that are the same size, runs those game systems and under $120??

I really wanted a ps vita for emulators but I heard they're not the best either.
