Possible v2.0 Homebrew Hack

**candrews** · August 7th, 2005, 06:00

i think the hardest part about making a homebrew firmware is being able to hack it and put it back to gether with out loosing the keys to make it work or get through the encryption.

I use a homebrew firmware for my MP3 player its called rockbox for the iriver ihp140.

Im not a programmer but what they did is very sligtly alter the firmware so when you turn on you can choose to boot the original firmware or choose torun a completely new operating system from its hard drive.

Imagine turning your PSP on and choosing sony firmware for your UMD games or boot a OS from your MS to run homebrew on!

The advantage with that is obvious! but also means only slightly altering the sony firmware.

Maybe there is someone who knows what they are doing should speak to the rockbox folk they have a forum on www.misticriver.net

Somone will finely some day. Alter a firmware for the psp.
I dont know if you would find such a thing here tho.
DCEMU prides itself in being legit. And I pride myself in knowing that Dcemu will be around for a long long time because of that

I dont think creating your own firmware is illegal!

Altering sony's though probably is!

But even tho it would be possible to create your own firmware from scratch.
One would almost have to alter sonys firmware to do it within one life time.
To build an entire firmware from scratch and not take anything from sonys firmware. OMG just thinking how genius one would have to be to pull this off and make it work. I dont even think the average genius could do it

Thats not to say its impossible. Just that its not likely to ever happen

Doesn't matter if someone creates their own firmware for 2.0 users, the eboot still has to be signed with the correct digital key (which no one knows)

Wouldnt a brand new firmware have its own eboot?

First of all if somone created there own firmware,
It would most likely be open source and nothing would have to be signed.
You would be able to run anything on it you wanted within the speficitacion tech range that the psp could handle it.
provided that the person that made the firmware made it completely open source of corse.

I think you're missing the point... Sure once you flashed your BIOS with this new firmware, nothing would have to be signed...

But you need to think of those who are upgraded to 1.51 or more. How would they get this homebrew firmware to flash their BIOS in the first place? IT would have to be signed!

say a firmware is created.....will commercial games still be supported.....the games the require updates to play? idk there will always be a hole in everything BUT hardware changes seem to be the only permanent solution because the community will go thu all this again when 2.5/3.0 whatever its called is released and all the new games require it.
