How to run homebrew that show as curropt (iRShell included)

Well last week I posted in the iRShell forum about not being able to run it in Epsilon BIOS 1.1 because it showed as curropt in the XMB. I asked then if anyone that could use DevHook could tell if it also showed as curropt in the XMB of 2.x fw (otherwise it should be a Epsilon only issue...).

I then got a PM from Haven in the iRShell forum telling me he tried the DevHook thing and that it did show as curropt. He also found the cause of the issue being that the CATEGORY padding in th PARAM.SFO was 1... All homebrew with 1 showed as curropt and with 2 showed correctly!

So the solution Haven found was replacing the PARAM.SFO inside the EBOOT.PBP with one from any other eboot that shows correctly and you can then see the app as normal in the XMB!

So if you follow the following steps all is well :

First you need some tools:

PBP Unpaker
PSPBrew (or Sei PSP Tool, PSP Content Manager...)

1-Extract the PARAM.SFO from an EBOOT that shows correctly in the XMB (you may need to convert 1.5 eboots to 1.0 first using PSPBrew... Then delete the % folder)
2-Extract all the files from the problematic (curropt EBOOT) using PBP Unpacker
3-Rebuild the problematic EBOOT but using the PARAM.SFO from a correct eboot (point 1). To do so make a "New" EBOOT in PBP Unpacker.
4-The text that shows in the XMB will be the one from which app you used the PARAM.SFO. You can change it to the original text (or whatever) using PSP Brew (or other apps like it).

Doing so most hb that didn't work will now be available to us Epsilon users (some others problems may remain in some though, but not related to this).

excellent find here is the finished result. I kept it as a 1.0 eboot because theres no need to hide corrupt icons and epsilon doesnt mind 1.0 eboot

iRShell on Epsilon.. HUZZAH! Wonder how long it'll take Epsilon to fix this... Does anyone here know how to contact them.

This is a really great find, I will try this method on other eboots that showed corrupt as well. Hmm, I wonder if it would be worth making some kind of list or adding attachments of the repacked eboots somewhere just like Irshell is in this thread. I don't know how many there are, maybe there aren't many.

I just realized you can do every step with PBPUnpacker ... Doh! No matter that also works and PSPBrew is a handy app...

The padding problem is probably part of the actual Sony fw. Maybe Epsilon can patch it in the next release. The icons show as curropt when emulaing 2.x firmwares with DevHook and in standard 2.x machines (when I had my 2.0, Squarez showed as curropt in the XMB).

I was thilled when I received the PM. If you want to keep track on the thread I started about iRShell see here. Though we can now use it, it still has some issues (check out that link) and I didn't test all iRShell functions... Give your feedback and maybe Ahman can sort some out...

There are still some other issues with other homebrew apps... The exit funtion is one of them... Try any gpSP and you'll get the idea (either try to exit using the menu or the home button). The problem goes from not exiting, freezing/shutdown and the blue crash screen... And unfortunately gpSP isn't the only one...

how do you rebuild it

heres the final vers 22 epsilon ready

Thanks, whacka

cant play umds through epsilon ready irshell

thanks though whacka

pm me with the working version if you can

Why PM? The file 3 posts above you works fine.

Did you try to launch via BOOT.BIN and EBOOT.BIN? One of them should work...

If not maybe someone else with the same game and Epsilon should try... Then a 1.5 user to see if it's an Epsilon-only issue (if there's any issue)

is there any way we can create a fix for PimP Streamer

thx

I don't have a wireless router so I don't really use...

I just used iR Shell as an example because it's a popular app. If the problem is that the Pimp Streamer shows curropt in the xmb, tthe fix is the same.

I didnt bother giving it a go because I don't stream or have my router set up either so I couldnt test it if it was a streaming issue

awesome, also works for fw 2.71 SE-B, i fixed several homebrew apps with your method
Fixed so far: CollecTic, WiFiSniffer, RINtest (Gameboy Emu), snes9xTYL ME (SNES Emu)
