you should be fine then. the reason i asked is because some games only work on certain versions (ff9 and chrono cross) and there are games that need specific settings enabled in order to work correctly as well. if you play from an image, make sure you create one in a format that has support for subchannel data because most psx games will not work without it. if you do not know how to do this, read
this thread.
i also suggest you read over the
FAQ because there is a ton of stuff in there that will be helpful when and if you run into issues with games or the emulator. and if you ever run into a game that just doesnt want to work with epsxe, another good emulator you could try is psx. its very easy to set up and while it cannot pull off the visual enhancement features epsxe and its various plugins are able to create, its a solid alternative to epsxe and some games actually work better with it.
