Kernel access with HBL

[aXe]

First i would like to greet everyone and to give my best regards to hbl devs for their awsome job.
I hope i'm not posting in the wrong section so here it goes:

I've found a homebrew which is quite useful to manage folders and files within the psp without the need to plug it to the computer. I've used it for a while but my suprise was when i realised there was an option to access the flash memory and also manage system files. My first tought was "It has the option but since i'm running it trough hbl it won't work" but it DID WORK! I was able tonavigate trough a serie of system folders and files with which i can do nothing sincemy lack of knowledge. But you is another story (not sure about that "is"). Devs are probably to find it very useful (so i hope) in hacking terms. I'm not sure if you can do something with it, maybe you already knew it but i'm just trying to help so here goes what you want to know:
-I run it for the last time in hbl rev.101 non-dev in a psp-3004 system with the 6.20 official firmaware.
-The name of the Homebrew is psp filer (idk know the version) but the folder it came in is named 'Kernel 3' so that's the name that appears in the hbl menu.
I'll would attach it to this post but the file it's to big even compressed so i upload it to mediafire: http://www.mediafire.com/?l0eg2p03ep5i2db . If you don't trust me download psp filer from psp-hacks (notice that i do not know if the current version works).

Sorry to diasppoint, but HBL is strictly user mode. This means you have read/write access to flash1, which only stores settings, and you have read-only access to parts of flash0. You cannot access any of the system modules (prx files) though.

Also flash0 access alone would not help much because you cannot simply replace files there since they have to be encrypted (with the correct keys for the firmware, so no downgrade through this) or the firmware fails to load them and you got a nice brick. It is probably a good thing that there is no write access in user mode or there would be quite a few accidental bricks when trying to modify flash0. In custom firmware this is not such a big deal because you can use pandora to recover, but you don't have this luxury on an unhackable PSP.

Ok thanks for the info (too bad it doesn't have any use ) but you can be sure i would never touch flash (not risking getting my shinning new psp bricked) xD.

You cannot access any of the system modules (prx files) though.

Just a little point: this is not totally true as you might already know. HBL can actually load some PRXs from f0 (most notably all utility modules). But as you say well, even if we had full f0 access, it won't change a thing.

heres something useful to do with filer for those of you that didn't know about it: you can use custom fonts by editing the "system.dreg" file and replacing it in flash1

heres the info

yes but its not recommended since you wont see some text because there is no font files for fw 6.20 as much as i know some font files are not showing

I highly suggest if you plan to edit the registry you don't do it by hand. Get font's into the fontmod folder(yes, it has to be fontmod, or atleast a 7 letter named directory, if you plan to do this by hand) and then run Skylark's old fontmod hack. Even 4 years later, it still works perfectly Same with buttonhack, I've used both on my psp.

Here is a link to get it, I will admit I'm not sure if this is the latest version, I downloaded the source and compiled it myself for mine. It should work though, since it doesn't use any kernel commands, it directly modifies the registry by itself.

It is a good idea to use both of these tools for the newbies who are un-educated on how to modify font. And don't modify the font on 6.20 since you won't be able to download anything through the browser and the info in the top right corner will look jumbled.

(Psp) Why if have fontMod on it then i download some stuff on internet i Can't save the file and i get error
