Since the cyclo support forums are down I did a search here but didn't find anything. I tried it on a game called What's Cooking and also Zoo Quest and got the error with both. I have plenty of room on my sd card (more than 250 mb) and I did format it with the sd format program before I transferred the games and my old save files from my R4. I have 1.54 firmware on it. Any ideas? These are both games that I did not have before and didn't have a previous save file for them. thanks
