There is a possibility that 2.8 can be downgraded through the TIFF exploit. For now though, we do no thave flash access on 2.8, so it cannot be downgraded yet.

we do have some kernal access on 2.80, becasue we can access the flash1 with the font hack and file assistant but we can only look and make a dump of the flash0

I see since tha flash has been stored it cannot be downgraded yet well i aint rushin but they already made tha 2.81 firmware and im not fenda upgrade ever cuz people used to think that it was never possible to downgrade 2.7 and + so im not gonna take any chances im stayin on 2.8 till they do something

would it not be possible to use devhook on 2.8 if it has flash1 access, or does it require flash0 access?
because then we could just emulate 1.5 in devhook!

I believe it needs full kernel access, as of the way it redirects flash0 to ms0...

damn... oh well, looks like well have to wait, unless some genius finds a way to boot a dump of 1.5 from flash 1, but i think thats impossible, isnt it?

you could make a fw emu from scratch using user-mode i believe but it would be a b*tch to code

I doubt user mode would do it, just due to the way it works...

well i dont know much about this but my theory was that there must be files on fw that interperet files on flash0 as a visable menu so f we could get these into elf format we'd be good to go because all it would use is memstick

user mode doesn't have enough memory to run devhook, it has trouble playing some emus let alone run a fw emulator which is why DA had to make the henC patch so it enabled kernel mode(which has a sh!t load of memory :D) for 2.71

would it be possible to create Hen-C on 2.8 or would that require access to flash0 and full kernal access?

Yea exactly like i said on my last post people said tha 2.7 and + could never be DG but look they may call tha 2.71 tha "Golden" firmware hmph!!! can u belive that? well its been a while since anyone said anything about tha 2.8 firmware lol i wonder whats going on well seems to me like this firmware could be tha hardest to DG flash1 flash0 shit load of memory lol wow alot of stuff to deal with just to dg a freakin firmware!?!?! im still on 2.8 and im just still waiting
