hi,
MegaTouch software comes in various versions, each year a new version was released.
Force lasted from 2002 - 2011
You can upgrade or downgrade the software however each version has a unique physical Key which acts as a dongle to allow the software to boot and sets things such as the game region.
So for example if you are running 2003 software you will need a 2003 Key to make it work, you cant run it with earlier or later keys.
You will quite often find machines with older artwork running newer versions of the software.
If your machine is not keeping the date/time you will find a CR2032 battery usually located on the motherboard, these are completely standard batteries you can pick up from anywhere, just replace the one on the motherboard, connect a keyboard, turn on the machine, go into the BIOS, set the date and time correctly, then save your settings and restart your machine, you should then be up and running.
Im afraid im not sure on the dollar bill feeder, maybe someone else can chip in on that one!
Good luck!
