This is a quick update which fixes 8001003C errors (for newer game updates) on all supported firmwares and also should fix some more issues caused by Iris/mM launched one after another. GOWA game should now work after installing 1.01 or later updates.
The update is also available online (if you start mM while holding L2+R2).
multiMAN v04.20.04 Changelog
* Improved discless compatibility (even more) on 3.55/4.21/4.30CEX firmwares
* A BD-DISC icon with [PlayStation(R)3] text will appear in XMB to replace /app_home/PS3_GAME entry
* Tested few games, which didn't work discless before and now work just fine (like LEGO:Indiana Jones, LBP2 and others)
* Upon launch mM will try to restore default LV2 environment by resetting syscalls 35, 36, 37, 141, 142, 600, 604 (this should fix problems when mM is launched after Iris)
