Hey there Matt! Here are some links to a couple things you might be interested in downloading.
I tried to find a small cheap USB thumb drive I could mail to you with the files, but alas, I could not find one. So I supposed you'll just have do download these files from here online. Shouldn't take you too long I hope :)
This emulator will actually only work on a PC machine. So you may need to install it on Leisha's computer. But if you can't get that to work, I can get you a link to one that'll work well for a Mac.
The reason behind all this? Well there may be a way we can play online together. So I supposed we'd best give it a try eh!
