Can anyone tell me what is wrong with my DS Lite? I got an R4 and a Kingston 1GB MicroSD. Everything's been working fine...until I used the ROM Trimmer that came with the CD, to trim all the roms. Then the problem start occuring. I was playing Portrait of Ruin, when suddenly, my DS went off on me. I tried again and again, and the same thing happens. I slot in my original New Super Mario Bros. and it happens as well. But when my friend played Phoenix Wright (on R4) using my DS, he could play it all the way till my battery went red without any problems... A friend of mine said it might be the battery problem. I found it doubtful since I got my NDS about 8 months ago or so, but I went to get a new batt anyways. Tried it, played Portrait, and the same thing happens... Any wise soul out there who knows what is going on?!
