time for a trip down memory lane lol
when the dreamcast was first cracked their was a bootdisk released by a group called utopia which was in fact a hacked demo from the official dreamcast dev kit called the teapot demo which utopia added a binary loader to the end of (and a funky raindeer)
utopia released a few games for the dreamcast (most of which got nuked for 1 reason or another) but kalisto started releasing high quality games which used the utopia bootdisk
after a month or 2 kalisto released the first selfbooting game (Virtua_Fighter_3tb_SELF_BOOTING_DC-KALISTO) which didnt require any type of bootdisk to run
a few months after that kalisto decided to quit the dreamcast scene for reasons unknown (not because sega offered them shares LOL) and echelon stepped up and started releasing
echelon then went on to release the echelon selfboot toolkit to help people make their own selfboot games from the already released non selfboot games that were available
although the echelon selfboot toolkit was really good it wasnt the easiest thing to use for n00bs so a guy called zerosoft (afaik) released bin2boot which was a all in one tool to make selfboot .cdi images of .bin non selfboot games
the utopia bootdisk can be downloaded from
