Sounds like you've done a good job there Haldrie, but as Drake said, I don't know of anyone who plays games on TI calculators, or even owns one. My only calculator is a Tandy one that just does sums for when I have to do my tax.
Anyone tried this thing, Microsoft Virtual PC 2004 ? It's recommended to use XP professional, although I'm told it will run with XP Home. Linkie I'm tempted to give it a go and be able to get rid of some old computers.
