I've just moved from 0.106 to the latest version of WolfMAME as I was getting huge frame rate drops, making an already nuts game even more difficult!!
I found your script online Xelnia, and modified it to mame64 instead of mamearcade, and it fires up ok, but seems to create one frame INPs. I got the z7ip part working ok by moving the exe to the root folder, but it seems that my INPs aren't recording. Batch file attached..
Any ideas?
