2. We'll just assume that you picked Boba Fett, unit # 1317.

3. Copy his header file, located in the civ0head.txt file, and place this in your patches:

civ_0_pointer_1317: 571947272
civ_1_pointer_1317: 571947272
Etc...
Do this for all 8 civs.

4. Copy his unit stats found in the civ0unit.txt file, and place this in your patches...
civ_0_unit_1317_type: 70
civ_0_unit_1317_name1_length: 15
civ_0_unit_1317_id: 1317
civ_0_unit_1317_language: 5122
civ_0_unit_1317_unknown01: ea 17 2c 00
civ_0_unit_1317_graphic_default: 6175
civ_0_unit_1317_minus1_01: -1
civ_0_unit_1317_graphic_die: 6177
civ_0_unit_1317_minus1_02: -1
civ_0_unit_1317_zero_01: 0.....
There are alot more lines, but to save space copy them all.
You need to do this for all eight civs.

This is the time to change all of the stats to that of your new unit(hitpoints, graphics, range, line of sight, etc.), then follow the step outlined below. Make your changes then hit edit.....select all.....copy.

It is easiest to paste "civ_0_unit_1317" all of the stats into your patches, then hit edit....replace... _0_ with _8_, then paste again, and replace _0_ with _7_ until you have all of the civs.

5. Find the master unit file, units.txt, copy this info into your patches...

unit_1317_exists: 1
unit_1317_count: 7
unit_1317_0_unknown01: 1
unit_1317_0_unknown02: 0 0 0 7 0
unit_1317_0_unknown03: -1 -1 -1 -1 -1 -1 -1
unit_1317_0_unknown04: 0 0
unit_1317_0_unknown05: 0
unit_1317_0_unknown06: 1
unit_1317_0_unknown07: 3
unit_1317_0_unknown08: 1 1 1 0 0 0 5 0 0
unit_1317_0_graphics: -1 -1 -1 -1 -1 -1
Get all of it....theres more....

6. In the same file, unit.txt locate this, and place in your patches...

unit_count: 1596

7. Almost done..., in the civ0head.txt locate this, and place in your patches....

civ_0_unit_count: 1596
You need to do this for all 8 civs.

8. Ok now to set up your new unit, in your patches file, hit edit....replace......1317 with 1596(the last unit in the game was 1595).

9. In your patches change the master & unit "counts" from 1596 to 1597. This is always 1 more than your last unit ID, because it starts with unit 0.

Hope this was helpful.If you have any problems post here, and if I answer your question, that may help others with the same problem.
