I was wondering is there is any way to detect in runtime if we're running inside DOSBox? Maybe exploit some quirk on the emulation that would allow probing the "system"? It would be useful for debugging stuff that's only available in real hardware ie: I'm working on OPL2LPT support for my games - having that output redirected to a regular Adlib (when applicable) would be useful.

Thanks!

Context: I'm using GCC 7.1 with DJGPP.

I am sure this question has been answered before. DOSBox has written DOSBox at several location in the emulation memory (like the bios name for example) (which you can find in the ROM at the right location)

This one checks for z: drive and some other DOSBox-only stuff:

Gonna check for drive Z in my debug builds. Thanks!

This is db-info.bat made by forum member Minimax, but be aware that there will be some incompatibilities with the latest versions of DOSBox.
