I agree . However, this is likely not the issue in this specific case, as if the cue file and bin/img file are in the same directory and the cue file gets read, but the bin/img file does not, the directory permissions are not the issue . The permissions of the bin/img file could be a problem, but …

Good to check just in case, but in this specific case, the error suggests that the cue file is being found and read, but the referenced img file isn't . In the limited tests that I have run, the mscdex error is not shown if the cue file is absent (not there or wrong path) or inaccessible ( …

Make sure the directory holding the bin/cue files is both executable and readable by the current user.

What are the external paths used when mounting the drives? If they contain a colon that isn't the second character, it can cause an issue like this. So for example "mount c cd:\" or "mount c hdd:\dos" is problematic, because DOSBox expects a colon to only appear after a single drive letter. It will …

I bought a Vantec adapter and it came with a "Flypower" PSU, the same as the one pictured earlier in this thread and the review that I linked. It failed after a few months despite very little actual use.

Instead of using the hacky -t option, use imgmount to mount an ISO or CUE file. It can mount files directly from virtual drives.

Vsync is disabled for OpenGL output since it causes issues when games try to output frames at 70Hz and the display only supports up to 60Hz. Pinball games are particularly susceptible to this because (unlike most games) they do actually generate 70 unique frames a second without any duplication.

To workaround the hotkeys switching the active terminal, you can run DOSBox with the "-startmapper" argument to open the keymapper and rebind the "Swap Image" operation to a different key combination.

It requires emulating the actual IDE/ATA hardware which is never needed for DOS games. Unless there's some way to make win95 access an ATAPI drive via BIOS calls, but I don't think there is.

If you're running it without an X server it won't be able to use the OpenGL output mode, which is required to scale the output to arbitrary sizes (like fixed 1024x768).

It's regular old CD audio, it wouldn't work if it was encrypted in any way (not to mention decryption would require more CPU cycles when the game was already pushing most systems to their limits).
