Download: PSP RCO Editor v1.15b
Changes in v1.15/v1.15b:
Fixed a bug in the decompression and GIM conversion routine
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
