I've been playing my epsxe games with .bat files so I could launch them simply with gog without having to link epsxe and open the menu and then select the game anyways with all my ps1 games . Anyways when I play a game that requires me to switch discs, I can't because when I escape, the basic epsxe menu also closes, or maybe it was never there because I never noticed it launched in the first place.
Here's my .bat file:

"cd "C:\ePSXe"
start ePSXe.exe -loadbin "C:\ePSXe\isos\metal_gear_solid_(v1.1)_(disc_1).bin" -nogui

I know it might have something to do with the "-nogui" thing, but when I remove it, it just opens epsxe and doesn't start the game automatically. If anyone can help or point me in the right direction, it would help greatly, thanks.
