Building - 987123879113/mame GitHub Wiki
Follow the "Compiling MAME" guide on the official MAME documentation website: https://docs.mamedev.org/initialsetup/compilingmame.html
You can use the SOURCES=...
command to specify what drivers to build, if you do not wish to have every game in MAME built into your Bemani build.
Modify the make
command to include the SOURCES
configuration like such: make SOURCES=konami/ksys573.cpp,konami/firebeat.cpp
. This will build a version of MAME with only ksys573 and firebeat drivers.
