PSP: Firmware 2.81 to be required for memory sticks over 4 Gig

[MikeDX]

I thought 2.81 was a security fix of 2.8 therefore 2.8 will see larger memory sticks.

if you boot up devhook with a smaller memstick, and then swap it with the 8gb once devhook has loaded, it will work, as long as you have the same devhook files on the 8gb memstick as you had on the smaller one. Swapping memsticks during devhook ONLY works when BOTH memsticks have the SAME devhook files (believe me, i've experimented with this). You could just use like a cheap 32mb as your "boot disk". Problem Solved.
