ZiNgA BuRgA’s increasingly popular Windows application has been updated to v1.12. RCO Editor is a useful tool aiding in the latest XMB customization craze — swapping the various icons found in [decrypted] .rco firmware files. Feel free to read more about RCO Editor in this forum release thread, as well, fetch some custom XMB icons right here.

To have some fun, download a PSP firmware update and PBP Unpacker. Unpack the PBP begin opening .RCO files; you may stumble across some icons you never knew where customizable. FW 2.50 is preferred.

Be careful!

Firstly, this has ONLY BEEN TESTED ON 3.03 OE-C and 3.10 OE. I believe it _should_ work on all 2.71 SE and 3.0x OE.
For 3.10 OE, customized topmenu_plugin.rco files won’t work, but it seems that customizing other RCOs (eg opening_plugin.rco) still works.

RCO Editor v1.12 changes:

• Fixed more bugs
• Added a text search function
• There’s now an “expert” mode (launch RCOEdit with the ‘expert’ command-line switch or edit the INI). This gives a few more options:
  • Access to Page/Anim resources – I’m not sure how these are exactly structured, but they are somewhat editable
  • Can change the visible dimensions on MIG resources
  • “Random Info” button just displays some, erm, random info
