Team XeDev released this first version of Dash Launch, which will allow you to boot your Xbox360 directly into homebrew software:
[QUOTE]
what it does:
waits for bootanim to finish, then launches a con (you don't see NXE dash)
currently launch.xex is built to launch xexmenu con at
Hdd:\\Content\\0000000000000000\\C0DE9999\\0008000 0\\C0DE99990F586558
install:
-put launch.xex in the root of your hard drive's content partition
-add the included patches to freeboot/xbr patchset (there is a bonus in there for those who don't have it)
xex source is included, in it's current form it does the minimal amount of work to launch the con if it's not present it should fail to dash with "could not load" error message
