Hello and welcome romi
First of, his name is GK
File 2 is my childhood game so I have no knowledge over File1 but I'm almost get the hang of it.
I have ps2 slim the console I used for the NTSC USA version for File 2 so now I use tap Emulator with smooth internet speed, I'll guarantee that in the future I will have the console for Japanese version for outbreak so we could play fairly using console.
Good Luck out there
