-now no boot.bin needs to be created to launch a gamecube

Browse Source 
game (better for the sd card), requires DML r52 or newer 
to work properly
-added new option in [DML] section, "dml_r52+", you
can set it to no if have a older DML version or want
to use the old boot.bin method instead to launch a gc game
