I bought this R4 card about a year and a half ago for my Palkia & Dialga DS Lite that I had bought a couple months after it had released. I used my DS mostly to play my GBA games as my GBA SP was lost in a move and Pokemon Soulsilver and some Mario titles. After I had stopped playing for a while, my sister asked for it and I decided to get her an R4 card so she could play some barbie games. After a lot of frustration back then, I got it to work. Created custom themes with pictures I liked and the works. I had a pleathra of games as well as cheats for each game. When my friend went to Marine boot camp, I gave him the R4 card so he could play whenever and whatever he wanted. Fast forward a year later and he had formatted the micro SD and lossed the kernel that worked. Now that I have, I wanted to just get it to work. I looked up every website I could, search various forums and the like to see which kernel I needed or if I was doing anything different from the first time I got it to work. I downloaded and tried a bunch of R4 kernels but to no avail. I formatted the micro SD to Fat 32 default allocation each time in between the kernels I tried and not a single one worked. I even tried using the Panasonic SD Formater in an attempt to get the damn thing to work. Here's a screenshot of what the various kernels held. I grouped the similar kernels together. The various websites I checked or got the kernels from: http://www.r4ds.com/download.htm http://www.r4wood.com/pages/Wood-R4-Kernel.html http://www.wiilovemario.com/new-nin...ding-original-r4-ds-running-firmware-1-18-fix http://wiilovemario.com/R4DS-Guide http://www.usar4.com/blog/how-to-set-up-r4ds-wood-original-flashcart-firmware-to-v1-62-for-ds-lite/ Please, if anyone could help or if you have the same card/ds as me, I would really appreciate any insight or even better, the kernel files. TL;DR Have this R4 card to play games on this DS Lite and have tried these kernels. A look at the contents of the kernels.
