Title: Didn't really know where else to put this, but...
Post by: bartre on June 13, 2013, 04:43:27 PM

anybody seen these mods?

http://www.mmmonkey.co.uk/sega-dreamcast-region-free-bios/

anyway, i'm sure i can manage those, but my question is, does anyone know where to source the chips (preferrably preprogrammed)
i tried the guy on assemblergames, but got no reply.

You could solder in a DIP42 socket so you can change the bios easily if they ever update it.
It looks to be straightforward. A 27c800 will be a pin to pad match for 2 to 43 of the original SOIC44.
 (Should be a piece of cake after all those Starfox2 carts )

Finding preprogrammed chips   :-k

well, which system do you mean? saturn or DC?
also, the only real problem i see with that course of action is a clearance issue, some of these are pretty constricted in space.
ideas?

If you can't fit socketed chips in there, Hobbyroms can probably hook you up with those SOIC44 Flash chips.
