Setting Up IV/Play
Click the IV/Play icon and you'll see one of two things depending on where you installed it.
1. You'll see a dialog box asking for the mame.exe file. Find it, select it and press ok.
2. You'll see this whatever you've done...
What it's doing is creating a data file of games called IV-Play.dat in its folder. Once done you'll get something like this...
IV/Play uses all the artwork, icons and data files that MAMEUI uses you just need to set up the paths for them. There's a page that shows you how to do this here.
To play a game just click the name.
