To answer your question, I don't think there is. The old (non-colour)Ti nspire model had a swapable keypad though. You could swap it out to a Ti-84+ keypad which for the most part functioned as a TI-84+ and was compatible with most games. The newer models would require an emulator of some sort to do such a thing, and I don't think there has been one publicly released(or in a completed state). The nspire does have several games released for it though, and a few emulators (Game boy and NES being the ones that readily pop to mind).
www.ticalc.org is a great resource for that. You should look into that and see what games are available. Oh, and welcome to Omnimaga!
