UMDumper is the popular UMD dumping software authored by PhonicUK in C. It is the only current dumper for 3.xx kernel that will rip directly to CSOs without requiring any extra steps. It is also the fastest of the dumpers out there due to its use of multithreading and asychronous IO. Supports both fat and slim PSPs.
Changes:
* Multilanguage Versions! (New to 0.2.5)
* Minor ISO speed improvement
* Hopfully fixed refresh bug when using the mini-game in ISO mode.
* Misc other bugfixes (Stops some mid-rip crashes)
