/vr/ - Retro Games

I am starting a collection of retro game carts while emulating the games I own on my steam deck. how big of a difference would the OLED make retro games look compared to first gen steam deck? is it worth upgrading for the better color and longer battery? I may sell my first gen to a friend. deciding what to treat myself to when taxes come back.

open to other possibilities of handhelds for up to psp graphics
