Team M33 have released an update to Firmware 3.51 M33. The update adds an additional NO-UMD mode that features enhanced compatibility.
Also, the team notes that if you have not yet applied the previous WLAN update, this update will patch the WiFi issue as well.
Update: Team M33 have released another update, now complete with plugin options for 1.5 kernel homebrew and NO-UMD bug fixes. Once again, this update combines all previous patches into one.
Update #2: These guys never sleep. Fifth update now out with more NO-UMD compatibility fixes.
This is an accumulative update, it has the features of previous updates (wlan fix, no umd), plus:
1. 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.
2. 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.
