Hi Everyone ! After some research in the forum , I´ve found this to use batch to use ECM Tools in within GameEx The idea of JK1974 is great , and helped me a lot to find the answer for my problem. Based on his code , I´ve modified it to apply better to my situation. So here´s my code @echo on set directory=%1 set directory=%directory:~1,-1% set file=%2 set file=%file:~1,-1% "C:\Playstation\packiso\unpakkIso.exe" "%directory%" "%ProgramFiles(x86)%\Daemon Tools Lite\daemon.exe" -mount 0,"%directory%\%file%" C:\Playstation\ePSXe.exe -nogui -slowboot I´ve made just a few changes... Well , I need help in the following. This batch file does it : 1-Run Unpackiso to Unpack my game and get it ready do be mounted by Daemon Tools 2-Mount the ISO file 3-Run epsxe. My problem is , after unpacking the ISO , the BIG *.bin file stays in the folder. And if I want to play the same game again, I will have to wait (a lot) the unpackiso process finish again. I want that the Batch file check if a *.BIN file is present , and if yes skips the process of unpackiso. Going right to the Daemon tools step. And after that , mount the *.cue that is already present in the directory. Thanks to everyone !
