This is the driver I'm toying with ... I hope that a kind soul will scrap that completely and make a nice bus/card system for the MFA smile

mfabfz.cpp

I've added the entries


Code
createMESSProjects(_target, _subtarget, "mfa")
files {
	MAME_DIR .. "src/mame/drivers/mfabfz.cpp",
}

to mess.lua
Code
@source:mfabfz.cpp
mfabfz                          // (c) 1982 Berufsfoerderungszentrum Essen

to mame.lst

and

Code
mfabfz.cpp

to mess.flt

Then I've compiled with REGENIE=1

The driver file gets compiled, but after that every attempt to get it linked results in

Code
