"This tool takes an elf file compiled for psp and "converts" it into a PBP file.
You can then copy this pbp file to a subdir in "PSP/GAME" on your memcard (eg to "PSP/GAME/APP1/EBOOT.PBP")
This tool has been designed so that you could run it at the end of your makefile,
you could even set your makefile to then copy the pbp to your psp after making it
(assuming you first set your psp to usb mode).

Let the pspdev begin! "

"Ver.3
Slightly updated version of the elf2pbp tool.

The included param.sfo file is now made as simlpe and generic as i could
while it would still work. You can now also set the name of your app from the command line

eg: ebp2elf main.elf "My First Demo"

What exactly does this mean?

Get a compiled psp .elf file and convert it. If it's anything like malloc(?) mentioned then the resulting app will run on a firmware v1.0 PSP.

Or not...

These guys have a lot of other releases on the site; anyone use any of 'em?

It is only for Version 1.00 PSP. There is no encryption of the ELF file. And I looked over the source code and it says "tool to quickly convert an elf file into a pbp for running on a v1.00 psp".

So for all us 1.50 PSPs out of luck so far. Back to the drawing board.

hmm... maybe the way to go... would be to find out how to go back. Someone with a 1.0 psp has to find a way to get it all off of there...

Still doesn't obtain the ultimate goal well atleast for v1.0 it will. The ultimate goal would be to run code on any version regardless of firmware.

This appears to be nothing more than what malloc was stating.

This is interesting, but has anyone actually tested this on any 1.0 machines? for all we know this could be fake. as well who has the 1.0 models? are these the prelease or the japanese models? if its the jap model then i could get my hands on some of that(china town) else, this is useless.

The original japan models were shipped as 1.0, but word is they ship as 1.5 now.

Thanhda · Joined: 09 Apr 2005 Posts: 331 Location: Canada

hmm, but i'm sure they still have some 1.0, but i check with my friend and they sell them for 500CAD, O_O. too much $$ to risk. but has anyone confirm whether or not this is real or fake? where there any US models that where 1.0? or where they 1.5 as soon as they came out down here.

uplink242, I'm sure Sony can't make a mistake like that.

> just to recap:
> a PROPER PSP - ELF/PRX can be executed when substituted for the LOADER (xxxxx.PSP) in the PBP packet on ver 1.0

Just to clarify:
This is a *claim* made by "malloc" on another thread.
[give or take calling it a "LOADER"]

The ELF2PBP tool assumes that claim is true (similar to other PBP packing tools - not rocket science)

----
AFAIK this has not been independently verified/reproduced.
I haven't seen a photo (or ideally a movie) of a PSP running custom code.

There are a lot of hoaxes floating around out there. This one does sound like it may work -- but sometimes things sound too good to be true ;->
[fact or hoax? -- I'm reserving judgement until I see someone running custom code; or instead a week goes by with no confirmation]

just to confirm, my japanese PSP shipped with version 1.5.
1.0s will probably start getting very rare.

actually elf files may not run at all, I hear they require PRX files only

Neila, please settle down. Uplink242 is just trying to say there isn't any known proof from multiple reliable sources yet so people shouldn't get too excited. Believe it if you want, but don't knock him for needing more proof.

As an aside, v1.0 units aren't as uncommon as you'd think. Lots of folk on efnet #pspdev have them - I have two myself.

there must be people who have tested this, actually someone would have bragged with some shots of home-code running on the PSP, so it's doubtful... but who cares if we can't use it on the 1.5

People will know if this is true or false as time goes by. Try it out and see if it works, put some time into it. A lock of the other thread discussing this wasen't a hint for not discussing this further?

Nelia, I really like your posts. Hopefully, people will learn by your misstakes and stop typing random stuff.

This is a plain joke - why, if you know you have a version 1.0 PSP or know people are already coding on PSP would you play little childish games ooPo?

Surely a simple.. "yes, I have seen it", or "no it doesnt work" would make for alot more constructive comment? PSPimp.. what are you on about? How are they signing their elfs? eh?.. how do you _know_ there are people happily coding on their PSP's.. maybe with a devkit (even they are rediculously hard to get at the moment!!).. if you are telling the truth.. show some piccies, movies.. why not eh?

Imho, until someone shows some movies that theyve written and compiled for, and ran on a PSP, its all bs..

This thread is like a bunch of kids.. saying.. "My dads got a space shuttle in the back yard.. ".. proove it ..

Ok. I know it will be hard to believe what i type since this is my first post here but I am trying to research what I can on this tool.

Anyways here it goes.

1) I have a PSP with bios 1.00. Japanese launch psp all have bios 1.00. The 1.5 firmware update did not come about till the USA Launch. So it should be posible though import shops to still find 1.0 bios models.

Ps, Mine was bought back in december when it cost me an arm and a leg.

2) I dont have the PSP sdk on me (a coder at work does but since he is out all I could do was snag the simple.elf from his pc). So I have not tested far.

Ok so here is the results.

.) I converted the simple.elf file with this tool. I uploaded the file into the location the tool says to. The bios detects the file ans shows me the custom icon used. When I execute the file the PSP does boot! (it shows the psp white logo and all). Once the demo is booted I get a black screen and see the memory stick light indicate it was reading something 1 time then after that does a really long memory stick read (i think trying to read the contence of the memstick before returning to bios). After this the program returns right back into the bios with no message.

I further played around with things. I found out two things which lead me to believe some code is actualy executing.

1) If the file is ran with the bay drive closed and a UMD in it (ape escape) I return to the bios after the 2nd memstick read flash with no error message.

2) If the file is ran with the bay drive open or no UMD in it I return to the bios after the 2nd (and rather long) memstick flash with an error message "The game could not be started. (80020001)".

So there you have it. I might try installing the SDK on my pc to see what I get in the next few days (would do now but of course at work and busy).

I hope some of this is helpful in some way.

Until there is proof, I agree... it is absolutely 'bs'.

How about uploading a video? It would be a good proof of it.

sure if you can deal with taken by a cell and have a place for me to upload it.

Sorry I'm a n00b, but what can you do with an "elf" file?
Can you run all kinds off homebrew software? Like emulators?
