This is the first time I'm attempting to run mess by the way. I'm a programmer and not new to emulators however, and I wanted to work on the SD-1 emulation and others. I've compiled mess and mame from source and verified that my build runs a couple of known systems.
So do you guys know why, if I do:
Error: unknown option: -midiin
but if i type
(note missing parameter)
Error: option -bloom_scale expected a parameter
This indicates to me that there is something wrong, perhaps the -midiin option has disappeared by mistake.
