'ello all,

Have been wondering about this for a long while, ever since seeing my
buddy's CDX and its differing bios. Is it possible to update your Sega
CD's bios?

No Sega CD unit has a writable ROM chip. The way to put an updated or
modified bios in your unit is to write it to a compatible chip and replace
it on the board, which is impractical for most people. This is especially
impratcial on the CDX, which has all tiny SMD components.

-KKC, who wonders what the current hot J-pop is.

Ah, ok. Thanks for the input. It was something I had always wondered
about, but never really researched. Those newer SCD Bios files are
pretty slick looking, I like the work they did on the CD player dash.

FWIW, I have a model 1 Sega CD (and a couple of Laseractive modules)
that had a socketed EPROM. But you still need a 40-pin programmer.

Anyhow, I see no point in putting a model 2 bios on a model 1 unit. The
problem is that it could expect slightly different hardware. But putting
different region bios can actually be useful... if you can patch it to
not check the console region first.
