The DC Bleem's were versions of Bleem made specifically to run 1 game, GT2, MGS & Tekken 3 were the 3 games the 3 Bleemcasts were made for before Sony & their meddling got in the way. Of course as [vEX] says running it in Chanka would result in a slow & not very enjoyable experiance, never tried running it in there myself as I dont have any Bleemcast discs but I'd imagine it wouldnt be too good to do. your second idea of usin ePSXe & turning up/on the filtering effects in the plugins would defiantly set you in better stead for an enjoyable game of GT2 or indeed any of the games Bleemcast supported.
