I have a PS1 9001 and I was curious if there could ever be someway to allow all models of the original PS1 to have an internal solution to loading backup games while also being able to keep the disc drive in the system. Something similar to the Saturn Switcher could work I feel. Maybe an internal PSIO? This could possibly allow all PS1s (excluding the PSOne) to be able to load games digitally but also use the disc drive and not have something sticking out the back or just having the disc drive removed.
