Hello,
I'm trying to run an old allegro game (probably written using djgpp). It fails in Windows so I thought I'd try DOSBox.

When I mount the drive and run the game all I get is 'load error: no DPMI'.

Any idea what to do to fix it?

You need to put the DOS extender (CWSDPMI.EXE) in the directory alongside the game's executable.

Works a treat, thanks. Just hope that file wasn't a virus
