# The list of ROMS is the intersection of the set of ROMs xroar loads
# by default, and the example commands in Readme.txt. Adding a ROM is
# as simple as adding it to the .info file, just make sure the download
# links line up with the md5sums.

# 20220315 bkw: BUILD=2, use symlinks for duplicate ROMs.
