No point on a Duo-R Duo or Super cdrom2 as they are already have V3.00.
If you load up the original bios onto a V2 everdrive it works, the rams already there.
I use it like this all the time as it saves taking the Everdrive out.
I guess this is only worth doing for any setup that is not native V3.00.
NO!!! Please do NOT do this!!!Some information has come to light recently that strongly suggests that doing this is a VERY-BAD-THING™.
All indications are that running an un-modified Super System Card image on the TED2 will cause bus-fighting between the TED2 and the built-in 192KB of SCD RAM.
It looks like the SCD RAM wins the fight, and that it works ... but you are putting unusual stresses on both the built-in RAM chip and the TED2's RAM/level-shifters. That is a bad thing, and may well lead to premature failure of either the TED2 or the console itself.
The patch that I've done fixes the problem so that there is no bus-fighting, and so that it is safe to use the TED2 to run CD games.
It is actually
more important for DUO/DUO-R/SuperCDROM owners to use the patch than it is for Briefcase owners to take advantage of the ability to use it as a Super System Card.
See this thread in the Development Section for details of the problem ...

http://www.pcenginefx.com/forums/index.php?topic=20120.msg436169#msg436169I have a briefcase and V2.4 card to test.
That would be great, I'll PM you.
P.S. It is
possible that KRIKzz worked-around this issue in his hardware ... but all the indications lead to the conclusion that he's
not done this. After all ... the card was never designed for, or meant for, running CD games.
