at first, i thought the emulator is running too fast (333MHz), but it seems to be the NTSC-mode. when switched to PAL, the speed is normal (at least it is the speed i remember from 15 years ago :P ).
also i noticed that after (quick)loading a snapshot the sound is messed up or completely gone.
how do the snapshots work? i thought, it's just a C64er-RAM copy, isn't it? if yes, i don't understand this problem.
an .ini-file / configuration-saving feature would be great in the future.
keep up the good work :)
