[WIP]: PSP Bios (RM)

Post by legendmythe » Mon Apr 11, 2011 4:50 pm

Hi, today I reached my 1500 line of code :D so I decided to post a little work in progress.

This homebrew is basically a simple recovery manager, but with more functions and faster, for instants whenever you change the iso driver it takes +- 1 second, but on my RM it only takes +- 0,5 second :D. Other fucntions that I've added are: Dumpers( flash1-3 and ipl) also I've added hardware information (like in the pandora menu) also I've added PSP stats, this just gives some info, not very useful unless you're a developer of this RM.

If you wan't you can download a Developer version of psp Bios, but remember some functions are buggy and boot time is not super fast. Also for the moment it works best on 5.50 Gen-d3, it might work on other CFWs.

!!! IMPORTANT: THIS MIGHT/WILL BRICK an Unhackable PSP !!!

Known bugs:
Might brick un-hackable psps
The 0mHz bug=> When cpu speed is set on default it will show 0mHz
Memory dumper => just won't work :c
Exit doesn't work in Eboot form, but that just because it's not made for that.
No Plugin support (it just a pain in the *ss to program that...
Launch Eboot.PBP at Recovery doesn't work either...

Also quick note for debugging purposes the RM is in EBOOT form later , with the full alpha release, it'll be in prx form to store on flash0.

Please tell me what you think, or if you'd like to see something added.

Nice, but your RM still needs some... ekhm... improvements. First, some options won't work (ie. "registry"), and in psp stats should be "Total 32MB ram" on Fatties). Oh, and you mustn't divide battery temperature by 10.

Here are some screenshots, what I think will inspire you a lot:

Have a nice work :)

PS. What are doing options "dump lower/higher 16mb of flash rom"?

//EDIT:
@MegaWaca - I think you can try it on your PSP safely, there is no flash0 messing functions.

No! It does some stuff to the Flash0 and writes to Flash1 so don't try this! Later I might make one for HEN/LCFW but this one is only for Hackable PSP
The Dump higher and Lower 16Mb, just copies the first 32 Mb of Lflash in 2 a *.bin files, it's not super useful though...

I've done reverse-engineering (yeah, it sounds proudly :D) and you are using NO FLASH WRITING FUNCTIONS (all sceNand imports are about READING flash). And I didn't found "flash0:" string in data section of your RM. I know you are using example code from other programs (there is nothing to be shamed, especially on the beginning), but it will be nice if you read pasted code and understand what it is doing.

So it's 99% safe to launch your RM on 3k/GO. What about this missing 1%? In Poland we used to say: If you have bad luck, brick will smash your head even in wooden church.

No I'm doing some "research" on my pc right now, you just gotta be focused all time, I already found 80% of my code but then I have to take that and put it in psp form and make it work nicely in my menu...
And ATM I'm getting a little sick of software... Hopefully I'll finish it up in 1-2 weeks.
