hey guys...this may already be common knowledge..but i searched the forums briefly and didnt see it mentioned. i was looking around at mame stuff the other day, and ran across this:
http://tomspeirs.com/mamescreensaver/it is a windows screensaver that runs mame. basically you install it, tell it where your mame executable is, where your roms are located and a few misc other things...and when your screensaver kicks in, it will launch mame and play a random game for a set amount of time (that you configure) then it goes to another random game and so on. the best part is that at any time, you can interrupt it and start playing that game simply by inserting a coin. if you press any other buttons, it will just go back to your front end or whatever else you had up on the screen..but when you insert a coin, you can then continue to play the game like normal.
this is a great way to discover new games..plus it is better than just playing a slideshow of snaps. I have discovered quite a few fun games that i had never heard of before.
i found this software to be a must have for my mame cabinet, and i figured you guys may appreciate it too.
enjoy.
