My friend gave me a file for psxe 1.7.00 a few weeks ago and the folder for digimon world 2, from this site. After configuring the psxe properly and putting the file into the iso folder, I was able to play it. A few days later the game went black screen on me and from then on, no matter how many times I re-installed both game and emulator, even installing the most recent emulator I still can not get the game to launch. Any advice?
