there are some games that dont play well on bleem but its the same with pcsxbox. these are the games i play on bleem strider2(main character sprite slightly glitchy,when screen is busy,but extermely playable). r-type delta-100% playable no glitches g-darius-some flicker now and then when it gets busy but again 100%playable metal gear solid-actually looks better than the ps1 original tekken2 and 3-extremely playable,some slight slowdown now and then,but no great shakes rave racer-100% perfect and loads more...... there is a compatibility list somewhere on the net with all the ps1 games that have been tested on bleem. bleem actually improves the textures and polygons of the ps1 originals,so they look sharper. i think the psp does the same with ps1 games,but i could be wrong there. edit/best thing about bleem,you dont have to mess about with a load of settings like you have to with pcsxbox.
