Have jst recently updated from a DS to a DSI and am hoping that I can upgrade my DS R4 card(s) to work in my new DSI. I need help in how to do that does anyone know how to and in fact can it be done? Is the hardware the same and can I just upgrade the software and are the games for DS and DSI the same?
Nope. You'll have to get a new flashcart. I suggest the Acekard 2i. - http://shoptemp.com/products/Acekard-2i-Card-for-Nintendo-DS-DS-Lite-DSi-p-30.html
nope sorry but your should get a iedge there the best at the moment get one here www.consolemax.co.uk
but iedge has a lot of software update so all the newest games work and it has a lot of updates at least one a month... so i think there the best and have a good team that will respond to your emails. and a upgradeable bootrom so it will get past all the future updates on the dsi.
