Bugfix for the released yesterday no-umd. This should fix the exit to the XMB with error 80020001 that happened to some people, or reduce its appearance. Added plugins options for homebrew that use 1.50 kernel. The file to be used for it, is ms0:/seplugins/game150.txt. There is other bugfix, but we don't know if it will make much difference in compatibility. In order to make compatibility tests, please remember that your ISO shouldn't be more than 54 chars.
