yeah, thats become a habit of mine since ever modding my 10000. i ALWAYS start the system without the memory card in, even in the hdd/na isnt connected. so yeah, i already knew about that one. and yes, that is true that games do use the hdd even without the memory card. ive had the hdd turn on at the wierdest times before for no apparent reason (and the memory card isnt in either), but it appears youre explanation puts some sense to that.
as for homebrew stuff, i gave up on that kind of stuff with v0 when i realized devolution mode didnt work when i first installed a dms3 in my v0. I've got other units/friends unit to test homebrew stuff on, so i dont really care about that it has so many problems on v0, and i dont really care about ps2 homebrew anymore since i've basically been "out" of the whole ps2 scene for over a year. However, i have a good memory, which is why i can still provide v0 information. I personally think that dreamcast is a better system to do homebrew stuff on anyway.
but yeah, thanks for some extra information i didnt know l_oliveira
