First off id like to say that i wouldnt put a custom firmware on my PSP because i dont feel the need, but what concerns me is the threat of Legal action from Sony because of the custom firmware, are they fully legal, are the downloads legal?
What also concerns is that there could be a potential time bomb bricking code within a firmware released at some time that could render your PSP dead.
Also Sony will strike back, we know that they are preparing an attack on the devhook releases with extra code to prevent future firmware hacking and with all the info that the PSP scene presents publically you can guarentee they will be applying fixes, esp because their PSone emulator is coming soon.
What do you think about the issues ive raised, do you have your own concerns, reply via the comments.
