revert cobra blackfin patches added in 3.60
Cobra Blakfin patch is as follows:
time = sceKernelGetSystemTimeWide()
// do the gc authentication
time2 = sceKernelGetSystemTimeWide()
if((time2 - time) > 50000) goto fail;
or tl;dr if gc authentication takes longer than 50000 microseconds, then the authentication fails.
