bleem! is an emulator which allows you to play PSX games on the PC, theres even some new bleem! emulator which allows you to play Dreamcast games on the PS2 or the PC or vice versa, not too sure. But basically all bleem! is, is a program that installs from a CD that allows the computer to recognise the PSX CDROM. You need the actual Playstation game to play it. Alot of the early PSX games are working with bleem! but not all, and a great deal have only partial compatibility, meaning that there are sound and graphic glitches. these games are playable but alot of the features have not been implemented. If you have a Playstation and would like to play your games with better graphics, bleem! is pretty cool, but I recommend you download the demo from
http://www.bleem.com or you can download the illegal version which I in noway condone.
I recommend trying this out as the demo version doesnt have all the features implemented, use the full version from the cracked site ONLY as a temporary test. If you like the program go buy it and support these guys. God knows they have enough trouble from Sony and PSX game developers as it is without people using illegal versions of their program and not getting any cash for it. As I said I DO NOT condone the use of the illegal copy, if you wish to use this you must find it yourself.
