Bleem! for Dreamcast allowed you to play specific PS1 games on your Dreamcast without any mods, with better shading and in much sharper 640x480 resolution. This set includes a Bleem! boot disc, and both discs of Gran Turismo 2 Rev 1.3, the most compatible version.

NOTE: All Dreamcast reproduction games include a full manual, and region free disc. NOT ALL Dreamcast systems can play CD reproductions, your Dreamcast must have been manufactured before October 2000, Dreamcasts manufactured November 2000 or later most likely can not play reproductions, but they are far less common systems. Look for the sticker on the bottom with the date on it, and a number in a circle near the word PAL or NTSC, if the number is 0 or 1 you can play reproductions on your console.

Please check that your console is capable of playing them before purchasing.
