I bought an everdrive 2.5 back in May and among other things was looking to play the X expansion kit, but I found that when I tried to load the X expansion kit ROM (from 64dd.org), the game starts to load and then the screen goes black, and my TV produces a No Signal message permanently (until I restart the console anyway). I tried both the english and japanese versions, as well as a Japan Pro Golf Tour 64 download and none of the DD games load at all. Every normal non-DD ROM loads perfectly and is playable with no issues; it's only the DD games that will not load. I'm using a 16GB SDHC card formatted in FAT32, and also previously tried a 4GB SD (nonHC) card in FAT32 which functioned identically in this matter.
I would appreciate any assistance or suggestions for this. I meant to research more once I got it, but time passed after I was unable to get it to work myself and I got frustrated and dropped the issue for a few months.
