Цитата:I want to do this thing , but so far didn't found any scheme of how to do it .As I understand SWAT said that this is possible no matter of what BIOS are flashed.

Need rewrite BIOS. BIOS send to GDROM command INIT, if GDROM don't answer COMPLETE then Dreamcast don't boot.

Can this be done ?
Because this is not my thing , I'm not that smart as you are .I mean I'm not a programmer .
I'm good with soldering iron and some crazy ideas for MOD's but thats it .
