Yeah, as i said, the "drive is empty" message meant it was unable to read your dump for some reason :).
It might be worth mentioning, i backported dump format support from kronos to yabause last year, which means it supports chd, cue/bin in a zip, and cue with multiple bins
We don't support 3rd party images, especially the ones loaded with ROMs. Note that selling preloaded RetroPie systems is against the project's license.
Use the image from retropie.org.uk/download to install RetroPie.
@mitu - Hey, that's nice, many thanks for the tip! I'll be adding it to my FBNeo list. Sometimes I miss those numbered ROM's at the beginning of the list as 3countb comes before 20pacgal for example, thinking it's not in the list. Computers and their sorts! :)
@RGCTech As I said, support for the Pi4 is ongoing and some bits might not work or function as they were on the previous PI models.
Try leaving aside the resolution change, since it's not currently not added to runcommand on the PI4. Use the native display resolution - which you can set it manually to 1080p if it's not automatically detected by using raspi-config from the RetroPie menu.
Stick with official plug and play devices like (s)nes classic mini
Start a new hobby creating your own personalized Retropie system by starting from scratch. It's not that hard. All the information is readily available on this website. You may want to invest in a quality micro sd card first.
@cowguy27 i guess the first thing i should have had you try, open up the .cue file and make sure the .iso or .bin is named correctly to match the real file. So if the iso is named dRacuLa.isO you need make sure the inside of the .cue file matches that. On linux case sensitive is important. Even on the file extension.
