Games not loading on one platform only

[LHensh]

Hi,

For some reason my Dreamcast games have stopped loading. BB will show me the loading screen but then kick me back to the platform menu.

I was playing these games earlier and haven't changed any settings since, so I'm not sure what's going on.

I'm using the Flycast core through Retroarch

So after a bit more investigation this seems to be only for games which I have recently downloaded from the latest redump and have not played yet.

These files are in .bin and .cue formats which I don't think are compatible with FlyCast?

How do I go about converting these files to a readable format?
