Included are both disc images of the original Gamecube release of killer7, and a PDF file of the original manual which has not been rereleased officially since the original release, and was quite hard to find a copy of online (at least for me). Game works in Dolphin, however it's worth noting there's a Steam version available with higher resolution options and closed captioning, if you'd prefer that (I would probably have bought that version but my computer wouldn't run it). In any case, I'll leave this here for anyone who would prefer the Gamecube version for whatever reason, or who would want to download the manual which is a notable addition to the game regardless.
