Developer's note:

Rcomage is a general purpose RCO creation/manipulation tool.A  It is designed to allow RCOs to be modified in almost any way, and intended to replace my previous application, RCO Editor.A  Rcomage should also generate almost fully "compliant" resource files (very similar to original Sony RCOs).
RCO files are resource files that can be found in the PSP's flash0:/vsh/resource directory which contain stuff like icon data and various other resource components.A  RCOs can also be found on UMD Video/Audio discs, where they are used to supply resources to the menus.
Currently, it only has two primary features - RCO dumping and RCO compiling.

Unfortunately, I've released this in a bit of a rush, so haven't really checked many things and haven't added many features I intended to put in.

Changelog:

- statically link all libraries; also now built with MinGW so MSVC runtime no longer required
- include required DLLs with GimConv
- fixed bug in GUI where it didn't chdir across drives
- partially removed annoying auto-fill for dumping RCOs for GUI
- fixed crash where bad label reference was supplied
- add like two additional warnings
- add ability to select zlib compression options from CLI
- partial support for reading big-endian (PS3?) RCOs; it's "partial" as there are still issues - mainly object handling is mostly stuffed up
- fix regression in earlier update which broke VSMX dumping
- minor changes to XML format
- apply hack which hopefully fixes up GimConv converting from some GIMs
- and if the above still causes GimConv to freeze, added a timeout to try to not cause Rcomage to lock up as well
- added "vagenc" and "vagdec" functions if you happen to want to convert a .vag file
- added "extract" function (not 100% complete)
