The support for the memory cards, it is not made in the same way that the ePSXe
The form in that the AdriPSX is executed, it can cause multiple incompatibilities
Put supposedly a better speed is achieved
The only game that detects the memory card1 at least, it is Breath of Fire VI, but not load
And, the way memory cards are being implemented (little by little) is not because of speed... but because of practicity.
If I get to be succesful on this, you will not be limited to 15 "slots" for every "memory card file"... but having separated savefiles for each different game.
