A project we should start

[IndianCheese]

We should start a project. We would take all of the files from a new PSP dump and attempt to map out the functions/purposes of each of them. This would make it a whole lot easier to attempt hacking on the firmwares. We may even uncover the homebrew patches and find a way to flash the old files into newer firmwares (I know, impossible on 2.01>). We already know a lot about them just from the file names--but we could go even farther by figuring out the other ones.

newb!!!!!!! :eek: what do you know jt3w you only have 3 posts.

Oh yeah, we're off to a great start.

Heheh... dont we already know all the functions?

[IndianCheese]

If we did, we would have hacked/flashed hybrid and custom firmwares by now. Going to work on one now...

[RedKing14CA]

You know enough about these to hack firware?

Well, I have created a custom firmware (1.99) that is supposed to have homebrew, web browser, locationfree, and AVC video, but for some reason it freezes when doing network, game, or video. Here is what I did:

Took 2.50 dump
Took 1.50 dump, pasted into 2.50 dump, overwrote files that were already there
Replaced all files dealing with video (prx and rco) with ones from 2.00 dump
Replaced topmenu_plugin.rco with one from 2.50 dump

Basically this is a 1.50 dump that contains all of the files found in 2.50 that were not found in 1.50 (html stuff, netfront.prx, etc.) EXCEPT for the video files from 2.00 (since AVC video is compatible on the firmware launcher with 2.00 only) and topmenu_plugin.rco (which contains the updated XMB with the network icon). Does anyone know any components I may be missing?

Indian, I'm GUESSING it's not a matter of what your missing, but more a matter of the parts being incompatible. We know that Sony has made a practice of changing even persistant components with each update, so even though you may have component A and component B, if component A looks for particular information in component B that isn't there, the two won't be able to communicate and will therefore be incompatible.

I dont understand you.

Mabye we should see if theres a way to decompile them. That might work. But mabye we should take 1.5 prxes and paste them over a 2.5, instead of taking 2.5 files and pasting them over 1.5 files. More or less the reverse of what you tried. By the way, i tried this a while back and got the same results as you. And for some reason, i decided to make my version number 1.99 also. Freaky.

[IndianCheese]

Thats what I did. So in the end, it was basically a 1.50 dump that included files that were found in the 2.50 dump but not in the 1.50 dump. Then I started editing the other files and so forth.

[kyle2194]

No, what im saying is, we should try to find out what file loads pbps, then put that in 2.5. Im off to replace every file one by one now!!

Heh, good luck! I think it would be much harder to get homebrew onto a 2.50 dump than to get 2.50 features into a 1.50 dump.
