first of all i have a Nintendo DS lite with a broken microphone and a Nintendo DSi version 1.4(eng) and my r4 is just lame and 'crappy' and dont work for DSi so i decided to buy an acekard 2i but the only two things i need to know is that if can be played/booted on nintendo DSi version 1.4 AND a good trustworthy online Shop for UK to buy It from
In order for the Acekard 2i to run on a DSi with 1.4, you need the "Danny Phantom update". If your broken-mic DS Lite still works, you can use that to install the update. Extract either one of the NDS files to your microSD card, run it on your DS, and follow the instructions.
