sorry, my fault: it's not ps1 (playstation 1), it's ps/1 (the Ibm ps/1 machines from the early nineties)
it's an oem version sold with the peculiar sound card of the ps/1.
I only have very few titles on the website, and it would be a pain in the @ss to sort through my collection, the games are all stored on one single dvd but many of the rar/zip archives have got obscure names and there isn't a doc or txt file with a list of the games with their titles written in full form. Unluckily I haven't time to do that but I know for sure that most of them can be found on abandonia or other abandonware sites. Except few rare ones.
