man im rooting for you do you think you could make it work for 2.71 seeing as there is a new 2.80 update

thanks man
and i might be able to
i hope so, if it works, ill be like woo hoo


and another thing that i found....
i was messing around with the SFO of an update file. and i noticed something pretty wierd
the signiture/bootname thingy said that the file could go inside the directory named something like PSP,,c*
so i went on my psp, and droped the edited firmware inside that folder and turned on my psp(1.5)
i went to its icon and it showed up
so i tried to start it and it said it was curropted after the boot screen... but this curropted showed what it usually looks like when you open up an update file on 2.7 or so. but if the file was a normal homebrew it would have ran (please do not get confused with my main project... i was bored so i decided to tinker around a bit)
but when i tryed on my 2.71 it said data curropt, and doesnt show the icon

i thought i would say this just because i thought it was interesting that the pbp files could have 2 folders, and i didnt know if people knew this or not
guh

and finally im back at my house so i can get back to work!!!

aight, so i decided to check if my hack was on the money, i loaded up the 2.8 firmware update on my 1.5, and it came up with that error, so im thinking man, it must be because i edited my flash rom, so i went to xflash, and restored everything. but wen i went back to it it had the same error! hmmmm
i didnt edit that update at all
which most likely means that my flash rom was modded, which, in turn modded the firmware update, without braking the signiture, because it was on the psp the whole time

now i got an idea, maybe i could code a game for 1.5, that when you open it, it looks for ms0://psp/game/update/eboot.pbp and edits it from there!
this could work, and may lead to a perfect pbp file, with the signiture intact, that runs on every firmware, under 2.8 (or maybe edit the sfo to say 9.99 fw update?)

tell me your opinion, i want to hear from you
