I found this on Google... it's a cache of the old compatibility list. Unfortunately, half of it is missing... however, you can access every letter category in the list by searching for "epsxe compatibility list X" on Google, where X is the letter you want to find. The first result should be the old list, however as it's not there anymore you have to access it by choosing the "Cached" option at the end of the description. Hope all that made sense...
