Hey, which rom are you trying to play, and with which emulator?
If it’s not showing up, possibly it hasn’t been sent properly. Have a look at this post. (Note it’s from the previous DEOT thread; don’t get mixed up with info!
Each emulator has an action.config file that recognised a set of extension. To the best of my knowledge, I’ve added all of the missing extensions, along with .zip and .7z, frequently found in rom sets. I mainly use Nintendo emulators however, and am less familiar with say, Sega, lynx, colecovision etc. If the game you’re trying to run is in a format that’s not listed, it won’t be detected.
Another thing. If you’ve got your gameshell on, and transfer the files over, they won’t appear unless you go into the list and push the X button to refresh the list. Refreshing the launcher by running a program and then exiting can also work. That and restarting.
This image should run exactly the same as a stock 0.5 image, just with better support. Did the game you are trying to run work on a vanilla 0.5 image? If it did, then I am super curious to know which one it is you’re trying to run. My guess is that it’s in a compressed archive such as a .rar and isn’t recognised. Either that, or the game could be corrupted.
See how you go!
