Storing the firmware on another chip isn't that big of a deal. A few people have already done that using a few blank flash chips. There is a few problems with this being feasable though. The first is there is two different types of 360 drives and only 1 has a flashable firmware at the moment, so a firmware chip is only usuable on half the systems out there to start with. They both use two way different types of flash chips, so I don't see how any easy type of plug on solutions would work. Thats what Team Xecuter were working on, until they discovered that in the past few months, MS has been putting big globs of epoxy over the flash chip, probaly in anticipation of something like this. The alternative if you don't want to try and scrap epoxy off 40 or 50 pins without breaking them, is to solder to all the via points. The one diagram I saw showed all the via points to the flash chip, and it would be like doing 30 or 40 DVD/CD via's or to go directly to the chip, soldering 30 or 40 DVD/CD points directly to the controller chip. There may be a few less points that are needed as the technique is refined, but right now I can't how they could make a feasable chip. And since the other firmware hasn't even been finished yet, I'm not sure how they make a chip for the XBox's without knowing how it's particular flash override would work.
