The PSP's flash contains numerous RCO files (localized resources)
in the flash0:/vsh/resource folder.  These files contain various
things such as icons, sounds, text and so on, which the PSP uses to
display the XMB interface.
RCO Editor is what its name implies.  Currently almost all of the
RCO can be edited in RCO Editor.  Some example uses:

• replace icons
  
• replace sounds - support for both stereo and mono sounds
  
• replace text (longer text is supported)
  
• modify some page and anim data

Random update on 18th October 2009
More bugs fixed - crash found thanks to byte.me, and some 4 bit conversion issues.  
You can get the updated EXE here - just replace the EXE in the package below with the one in the link in this sentence.

Random update on 11th June 2009
A number of bugs fixed in 1.15c.  I'm lazy so won't update the version number (actually, I'm getting close to finishing my rcomage program which will replace RCO Editor to some degree).  You can get the updated EXE here - just replace the EXE in the package below with the one in the link in this sentence.
This update just fixes a few issues with image handling (more specifically GIM«>BMP conversion).


Last updated, 28th Oct, 2007, version 1.15c
Changes in 1.15c

• Fixed another bug in GIM conversion routine

Changes in 1.15b

• Fixed a bug in the decompression and GIM conversion routine

Changes in 1.15:

• Rewrote GIM «> BMP conversion routine
  • Dimension restrictions removed, as well as the "visible dimension" nonsense (RCO Editor automatically fixes that)
    
  • osk_utility.rco icons no longer cause crashes
    
  • Support for creating 4 bit and 32 bit GIMs (previously, only 8 bit supported) - effectively removing the 256 colour restriction
    
  • You can now use ICO, PNG and GIF files as inputs, in addition to 4 bit BMPs
• Other minor changes and bug fixes
  
• Added option to disable compressing resources - this is for some 3.7x RCOs not working properly with compression enabled

So what sort of things can this program achieve?  Well, you can just take a look around the many themes which are now possible with this.  You can find a list of some themes here.

Okay, that out of the way:

3.11 has just been released!
A bug fix in an r-type thing or something.

Might confuse a few people.

Unfortunately, I don't know how to convert to the PSP's "icon format"... :(  But I was basically playing around with the system_plugin_fg.rco file, and found that it contained a few icons, basically:

• Battery icon
  
• Mute icon & shadow
  
• Lock icon & shadow
  
• Cross icon & shadow
  
• Circle icon & shadow
  
• Triangle icon & shadow
  
• Busy indicator animation & background
  
• Two more icons, which I don't know what they are
  

Meh, I was wondering what that file did, and I'm disappointed - that file doesn't do much :(

Well, I'm getting bored of my Simple Popstation GUI project...
So I thought I'd release the source code for anyone interested.  I may
decide to add a few things later on, but for now, I think I'll take a
break from this.

Anyways, it's not exactly a public release, but it's here if anyone wants it.

The code is written in VB6.  Note that although VB6 is typically a "n00b language" the code is certainly not n00b friendly.  A few more advanced things are used, plus I'm too lazy to add comments etc.

More info is given in the readme.  Remeber, read the readme!
File can be downloaded below.  (Note that will also need the compiled package which can be found here)


Oh, and it's interesting to see how much code I've actually written :)



Hope some people find this useful!

[quote=Sony]PSP®本体

Games like a Grrl Wrote:3.10 OE-A changes:

• Change from 3.03 firmware to 3.10
  Pops improvements:
  • Assign controller ports.
    
  • New screenmode options
    
  • Black level adjustment (for darker games)
    
  • Volume adjustment (higher volume :P :P )
    
  • Also seems to have higher compatibility, as well as some PAL support.
    
• 4th level of brightness (aka battery eater) can now be selected also without ac adaptor.
  
• Changes in hen core:
  • Static user elf’s can now be executed in the 3.10 kernel. (this includes snes user version between other programs)
    
  • Tyranid’s patch (added in 3.03 OE-C) consequences was not explained very well in the changelog of 3.03 OE-C:
    • For programmers: it allows kernel modules to have user imports, making kernel programming in 3.03/3.10 less strict.
      
    • For users: plugins and applications that worked in 2.71 SE, but not in OE, *may* now work in 3.03OE-C and 3.10 OE-A.
      

    Note 1: the installer will disable all plugins to avoid incompatibilities when booting. You can enable them again in the recovery menu.

    Note 2: the plugin to load 3.02 pops won’t work anymore in 3.10 OE, due to some changes in pops modules structure (meaudio fused with popsman, idcanager/idmanager behaviour slightly changed). A new plugin for 3.10 could be written next week.

Be aware that custom icons do NOT work with it, so if it's important to ya, stick with 3.03 OE-C.

Here's where to get it: http://www.psp-hacks.com/2007/02/04/cust...-released/

As always, this stuff does carry risks of brickage, so proceed with caution, and use at yer own risk.  Read everything twice, then read it again.  Great work Dark_Alex, keep on steamrolling $ony's firmware!

NOT :P hahaha

If you're one of the few people like me, who prefer PMP-AVC over MP4-AVC, then this might be a nice update :P  (mainly PMP-AVC allows you to save battery and has volume/lumi boost which can come in handy)

Well, I've followed the "unofficial" updates of PMP-Mod AVC v1.02M by Madrusco, for a while, but none seemed to be great, until this one:

The brightness level mod should be a nice addition, as well as the other additions.

For converting to PMP-AVC, XviD4PSP and AVItoPMP are both useful converters.

Quote:After much work over the past few days, wee finally succeeded - wee have an easy-to-use downgrader for v3.03 PSPs!

Some ground-rules:

• This downgrader is for v3.03 firmware only. But if you have v2.81 - v3.02, no problem - you can just upgrade to v3.03 to use the downgrader.
  
• You need a copy of the unpatched GTA:Liberty City Stories UMD. No ISOs, no patched UMDs, not Vice City Stories. See here for some info on how to check if your version is patched. The most reliable way : the unpatched disks have the v2.0 firmware update on them.
  
• This downgrader is intended to enable homebrew. Homebrew is NOT the same as piracy. Don't be a thieving loser - buy the games you play.
  
• The downgrader will work on all current PSP hardware (TA-079 - TA-086). Patching of TA-082+ is automatic in the downgrader.
  
• You downgrade at your own risk. There is always a chance of bricking, although wee have done everything wee can think of to make this process safe.
  

Full instructions for downgrading are included in the Downgrader_HOWTO.txt file in the ZIP file. Read them carefully! You will need:

• The 3.03 downgrader package
  
• Official v1.50 Firmware Update EBOOT
  
• Official v3.03 Firmware Update EBOOT (only if your PSP is not 3.03 already)

check it out everyone... THE DOWNGRADER IS OFFICIALLY OUT!!!!!!!!!
