Hi, A quick update to this. It seems to work when I copy over only one or 2 ROMs, but not when I copy over 700+. Perhaps this is where the 720?.nes file comes from? Not sure. Regards, Tom

Hi, Sorry I can't help, and I know this is a very old thread, but this is also something I'd be very interested in. I know of E-UAE, but I don't know how easily it could be integrated into recalbox. There is also UAE4ALL for the Dreamcast, which would also be nice Regards, Tom

@retroboy I don't suppose you have any more suggestions as to what might be going on here?

Hi I'm having the exact same issue. The recalbox Pi works fine playing ROMs, configuring Kodi and playing around with settings, but then I transferred a bunch of NES ROMs, rebooted the Pi and I got a blank screen with background music. It wouldn't recognise any input from my controller, so I rebooted but no dice. I removed all the NES ROMs but it made no difference. So, I rebuil the Pi and it was all fine, until again I transferred the NES ROMs over and it did the same thing. I removed the files but there was a '720?.nes' file there, which won't be deleted. I went to the web front-end and it displays an error about the 720?.nes file: <table class="meta"> <tbody> <tr> <th>Request Method:</th> <td>GET</td> </tr> <tr> <th>Request URL:</th> <td>http://10.10.75.6/systems/roms/nes/</td> </tr> <tr> <th>Django Version:</th> <td>1.8.5</td> </tr> <tr> <th>Exception Type:</th> <td>UnicodeDecodeError</td> </tr> <tr> <th>Exception Value:</th> <td>
