You can make a batch (in QEMU directory) to run MenuetOS64 in QEMU:
qemu-system-x86_64.exe -L . -m 512 -fda M64-094B.IMG -localtime
-m 512 - means 512MB of memory (transparency needs 512, without it you can put 256 there)
Just make sure your *.bat file and *.IMG file are in the QEMU root folder
There's also a QEMU Manager
