i'm a fan of these damn sd card adapters.
i still have yet to buy a gdemu.
more than likely most ppl will have multiple systems...
one with gd-rom, one with gd emu, one with a hdd
at least ppl have more options than paying what would amount to a used car for the insane priced original retail gd roms.
the dreamcast should always be an affordable system.
buy one of these sd adapters and then eventually buy a gd emu.
no1 truly cares if you have a sealed copy of mars matrix.
but by all means, its your money do whatever the hell you want.
