you know, a $25 modchip that is flash-upgradable using EvoX/XFlash would be amazing -- so amazing, in fact, that you'd think we would have heard something about its development...
if this is real, why isn't xbox-scene.com screaming about it on the front page? why isn't the entire xbox community chattering away with excitement about this chip? and why, on the premodded page, does it say absolutely nothing about this awesome innovation?
in fact, the description of the chip that GTac claims has this ability ("Prewired Sporty Custom-X Modchip") only says one thing remotely related to flashability - it says, "Modchip is socketed for easy removal and updating" (i.e. take it out of the xbox and use external hardware to flash the thing, just like every other homebrew out there)
