MemcardRex

MemcardRex is one particular solution you can take into account when wanting to access and edit data on a PlayStation 1 memory card. There is a plethora of supported formats including MCR, GME, MCD, MC, DDF, MCI, and many others. Do keep in mind, you don't have to own a PS1 in order to be able to edit these elements. All you need is to run a PS1 game on any Sony console and have a file created for the game.

There are some hardware requirements in terms of how to get these memory cards connected to your machine. One particular way is through a COM port which you will need to set up yourself. USB is another plausible way of connecting these cards to your PC. Some suggested setups can include Arduino-based projects or the PS1CardLink idea. Another possible solution is the PS3 USB adapter that requires specific PC drivers to work.

MemcardRex is an interesting application for PS fans who are also intrigued by the possibility of changing various files one can't really access easily. It can prove a great ally to those wanting to change PS1 save data without having to spend hours to find the right solution.
