Hey guys. I'm using an R4 SDHC Revolution and I've tried a ton of different firmwares, FAQs and tutorials. I've tried Wood R4 (latest version), original firmware v1.18, Ysmenu, etc. I've tried Plants vs. Zombies, Ghost Trick, and Radiant Historia. I've tried multiple versions of all three of those roms, including AP patched ones and none of them will work regardless of what I do. But I can run older games just fine. I tried it on my aunt's card, which is exactly the same as mine, and that didn't work either. My boyfriend has the exact same card that I have, and sent me his setup, and when I loaded up my DS, I got a message over top my boyfriend's background image that said "This is fake!!!" But Ghost Trick works perfectly for him.
