Yesterday i´ve tested the new scummVM ECS.
On my A600/ACA030/25 the games (for example MI2/IJ4) are unplayable with music. And without music its also not really playable (much slowdowns).
I´ve only tested with the standard options.
On the other side, the "first start, second fail" bug (scummAGA 060) is not in the ECS Version.
