Dreamcast GDI Compatibility List

[somacast]

update, i need help plz

now i changed bios to (dev + no gdrom)

but when i start dreamcast it comes to the black screen, finds hdd, then comes to last line below (no sd found) and freezes

tried also (retail + no gdrom) , same exactly

funny thing is when i put back the gdrom it works

what is going on really!!!
