Hi there!

Yes, thats the bug I found yesterday. Basically theres a chunk of about 100 bytes at the "join point" between the low memory copy and the main memory dump in the statefile (read that as: it doesnt save all RAM, it skips some bytes sometimes)

Thats all fixed in the new build we will upload shortl :)

In regards to the sound, there isnt anything we can do about it as its not possible to snapshot the state of the PSG sound registers 100% and this will happen in all games that dont "reset" the PSG again during soundplay.
