@charlesmarried ok so the full content of your DOSBOXBAT should be :
MOUNT C "./recalbox/share/roms/dos/alone.pc"
C:
imgmount d .\cd\alone1.cue -t cdrom
pause
c:
INDARK
you may have to rename the cue file in the cd subdir to alone1.cue, the bin file to alone1.bin and edit the content of the cue file : first line should refer to the right bin name alone1.bin :
FILE "alone1.bin" BINARY
all bin and cue names should use lowercase and nothing else
The pause command should indicate you if the mount of the cd went well
