i do have a dreamcast. i didnt know you could make it go faster however. you still cannot skip it. same principle as the bios on a computer, you can skip the ram count, but you cant prevent all that rom stuff from bieng displayed.
I think the BIOS screen in Chankast is infinitely less anoying than the multiple unskippable intros exhibited by a real PSX. By a faster CPU, and it'll go faster.
