So, I have an N5 card (which is basically a 1:1 clone of the R4 card/M3 Simply) and I've been able to load both the original (N5's use unencrypted R4 firmware) firmware and also YSMenu as dual boot systems, I got YSMenu from RetroGameFan's Multi-Cart. Most older games (2010 >) have been working on the original, but outdated, firmware, so I assumed these didn't have any AP on them, otherwise they wouldn't have worked. I dl'ed a pre-Dicastia patched ROM of Pokemon White and it's been working, using YSMenu, for a while. Using a clean ROM would just show double white screens, obviously the AP kicking in. So while using YSMenu + patched ROM, I would occasionally encounter double white screens while booting up the game, thinking that the AP finally kicked in. I usually fixed that problem by copying a fresh, new pre-Dicastia patched ROM. So I went and turned on my DS lite like normal and, as usual, opened up YSMenu. Everything was going good so far. Except, I was seeing double white screens, thinking it was its usual problem. I copied a fresh, new ROM and it still didn't work, to my surprise. I don't know why it hasn't been working as of lately; I never updated to any new firmwares or anything and I've been extracting that ROM from the exact same .7z file on my hard drive. How should I fix my problem..? I was thinking I could install Wood but I didn't think it was nesecerry due to the previous successes. Thanks for reading. Any help will be gladly appreciated. EDIT: "Would anyone confirm if Pokemon Black/White could run successfully on a Wood? I've played around with Wood before... I just don't understand why YSMenu would suddenly stop working. It works for other, older, and non-AP games (ex. Mario Kart)." from my below post.
