my dreamcast has gone down so thought i would try to see if the emu is any good, till i get another one. So i have downloaded a few games that i have and have got some to work but sega rally 2 wont its a .CDIfile the bios loads but goes blank, it did say it was bootable but it might be wrong. also i have set nullDC up to work right for my pc and was wondering will these settings work on every game or do i have to change them for differant games. thanks
