@Felthry PSPs really don't cost that much for a used one.
From what I remember, most PS1 games run well when converted to use the official emulator, and it can do most things below that, but for N64/GC/PS2, you'd need one of the newer Android/Windows handhelds
@Rosemary @Felthry I mean, N64 emulation might have improved since I tried it.
But yeah, for a portable emulation device, I can't think of a better alternative right now - a Raspberry Pi or an original Wii would likely be cheaper for a home based device, but making a RasPi portable seems like a more expensive option when factoring in the cost of the kit.
