Generating a Single Binary for Battlezone

The Battlezone ROM set has 16 files in it, but it's a lot easier to disassemble if you have it all in one. The MAME data file specifies their locations like this:

Filename	Size	Region	Offset
036414-02.e1	2048	maincpu	5000
036413-01.h1	2048	maincpu	5800
036412-01.j1	2048	maincpu	6000
036411-01.k1	2048	maincpu	6800
036410-01.lm1	2048	maincpu	7000
036409-01.n1	2048	maincpu	7800
036422-01.bc3	2048	maincpu	3000
036421-01.a3	2048	maincpu	3800
036408-01.k7	256	avg:prom	0
036174-01.b1	32	user2	0
036175-01.m1	256	user3	0
036176-01.l1	256	user3	0
036177-01.k1	256	user3	1
036178-01.j1	256	user3	1
036179-01.h1	256	user3	2
036180-01.f1	256	user3	2

We're only interested in the "maincpu" items. Putting the vector generator data at the end of the listing seems reasonable, so we want to collect them in the order shown.

Launch SourceGen, select Tools > Concatenate Files. Navigate to the Battlezone ROM directory, and add the first eight items listed above (just select all the files that appear to be 2K in size). Use the Up / Down buttons to arrange them in the order shown above. Click Save and save it as "Battlezone". It should look something like this:
