ttdsi help please

im pretty new to all this and have been using ttds on my mrs's ds, my mother in law has just bought a dsi and want the same, is it just a case of getting a ttdsi card and using same firmware and games etc as i do with ttds?

It is the same.Same card but works in dsi.It's only different if the dsi is above 1.4 in firmware...in which case you need to upgrade the flashcart to cancel that out.

Yes. The TTDS and the TTDSi use the same firmware, and can run the same games.If your DSi is on firmware 1.4, you may have to upgrade the TTDSi.
