They are top loaders, and why are no good is the fact that both the disc's sit on a spindle and spin. But over time they break, the game discs get tossed around instead of loading. My friend owned both systems. I liked them too, as I only own almost every portable gamesystem they have today from gameboy, sega,NEC, Atari. Lynx, Nomad, Turboexpress. I wanted a cube myself but after what happened to my friend 2x with the cube and 1 time with the ps1. Don't buy top loading systems.
