Saturn Expedition Committee has updated their Run UMD to version 0.01.01a Experimental. Run UMD is a homebrew program for enabling 1.50 PSP to run 2.00+ UMDs without having to upgrade the system software. This program is NOT an ISO loader program but a legal UMD launcher. You will need the actual UMD game to play. No changelog is mentioned in the readme, but hopefully the compatibility is now improved by a little.

Updated compatibility list:

* Mobile Train Simulator - Cannot start
* Talkman - Black out during the startup
* Monster Hunter Portable - "Character making" -> "Name entry" fixed, online mode unusable.
