Could anyone help me with my problem.
I can get the emulator menu up and can choose my iso. But after i pick it and the psp goes back to the start menu the umd still reads and plays the actual game that is on the umd.
I know im meant to change the mode to system menu so this is not the problem.
Would be gratefull for any help.

Make sure you read the README in the UMD Emu 0.8 folder to have files in the correct place and have the correct settings while in the program.

Just make sure you pust the UMD Emulator folder with the core.bin and menu.bmp files into the root or the memory stick (J:/) and have the .ISO games in the ISO folder also in the root directory.

If you have the correct files and settings start up UMD Emu, after you select your game it will go back to the menu w/o any (game can not be started) stuff, then you select the umd like you were starting the umd in the drive, start it up and it will start up the ISO you chose. The next time you turn on your psp after turning it off it will be like it normaly is, meaning when you select the umd in the drive it will play the umd in the drive. You NEED a umd in the drive to use UMD Emulator 0.8 or it won't work.
