Here's what's included, in alphabetical order:
Just a quick note: everything is running fine apart from Night Slashers and Dynamite Cop, which seem to be completely broken. The only others that have a slight problem are Mutation Nation and the Sengoku games. They work perfectly well, but as some file in the BIOS is "the wrong length", they don't show up in the 'Available' list, so you'll have to access them from 'All Games', at least until I find a version of the BIOS with the right file. (You can search 'All Games' more easily with CTRL+F.)
I use ShmupMAME, but I've included a couple of other versions (use whichever you want, really - you only need to hang onto the ROMs folder). If anyone hasn't used MAME before, let me know and I'll post a quick guide.
Edit: bloody typically, I missed a couple I wanted to include - 64th Street and Violent Storm. I've uploaded them here (alternatively, here). Also, Night Slashers works fine in other versions of MAME - just not ShmupMAME.
