Did you ever look at your collection of legally-acquired of course MAME roms and thought to yourself, I wish I could turn the attract modes of these arcade games into a screensaver? I thought that, and then thought, I should try to create one!
Then I stopped myself, and thought once more: before creating one, let’s use Google to try to find out if someone’s already done it first, save myself a lot of work, wot wot.
As it turns out, someone has made one! Currently it’s only for Windows, sadly, and it requires the NET runtime. It also needs you to have a stock version of MAME already installed. But if MAME is set up so it knows your rompath, it’s smart enough to ask it where to find them. You can even determine the command-line options that MAME receives. It’s nice! Which is why I mention it here! You’re welcome!
