[v2.0] PSCRYPTER for PSP, sign EBOOTS from a PSP with OFW

[Disturbed0ne]

I have a PSX eboot. Can I sign that and play it from my 3001 6.35 OFW PSP?

I don't think you can sign that (not only for the big size of those eboots).
As I can remember, for loading a PSX eboot you need a "popsloader" plugin.
Maybe the HEN has that ability though.

I've done all the steps but it won't run. It's got to be the size of the eboot. I'll keep trying things and see what I come up with.

Due to memory limits, i've set the maximum initial Eboot size to 4MB

I hope TN-C will fix this as I've read.

Is there a way I can pull up the source code and increase the maximum file size itll work on Eboots with?

Source is in first post, but I don't think it was the dev's choice to limit it, I believe that only binaries up to a certain size will work with this psuedo-signing technique (because the header is copied from a demo I believe).

Yes you are right.
I mean, there are two limits:
a) what you say, the demo code that needs to be 5.3 MB
b) the PSP RAM ~32MB

Though, I think it is possible to increase the buffer to 5.3MB to allow that maximum.

The buffers of the original source code were 20 MB... thats not necesary xD

Lets see if developers make some more progress

So whats stopping me from using a different demo?

And if possible give me a name of a simple homebrew that will surely get signed successfully so that I can try to sign that apps.

My app MultiTasKing is very complex and can be signed: http://carlosgs.no-ip.org:8080/PSPhomeb ... rlosgs.rar

your program works great, but you still need to have hen in order to use the "minidown" application inside, or it crashes.

It has to be a PRX based demo, and most recent demos (after around FW 2.70) are not. Recent demos are actually ISOs within EBOOTs. This trick will only work with PRX based demos, because the homebrew it works with are PRXs. I assume that the biggest PRX based demo is the one used for the header in this case. Therefore, a homebrew can be a maximum of 5.3MB PRX.
