Perhaps emulation might get you interested. Replay the games of your childhood. Emulation also offers save States so you can immediately save or reload without silly save point mechanics, though you can stick to that if you want. This would let you basically get 10 minutes in here or there.

Get yourself an anbernic rg351or other models, or a steam deck. Anbernic’s models can emulate generally up to ps1 and sometimes n64 or psp. I played through several childhood games on my 351m. Steam deck can emulate most things, namely ps2 ps3 360 and switch, but I’ve only tried psp thus far.
