Hello,
First excuse my english, if I do some mistake, i'm French.
I use Demul only for Atomiswave, like you I was looking for some solution with th ahk files and all the other files, doesn't work for me.
So I use the command line for Atomis and it's work like a charm.
- In maximus, took an emulator you won't use (commodore 64 for example)
- Configure the executable, roms path, snap... with the demul.exe path, roms, and other stuff you want
- In the command line put: -run=atomiswave -rom=%name
- In the scan tab put: .zip
- In the exit tab, check: close additional processes and also Close specific processes, and put demul.exe just under close the specific procceses.
Work fine for me, exiting and re-launch fine.
Hope it's helping.
