I made a cwad that includes an edited aiscript.bin I changed with my AIEdit. The patch allows you to use any AI script in Staredit. The Brood War AIs are set so Staredit rocognizes them as Brood War AIs. Some patches others have made have some AIs incorrectly set as Brood War AIs and others incorrectly set as normal Starcraft AIs.
Three new cwads are in StareditCwads.zip. The names have 'AR' in them. In these new patches, you can place units for any race for any player on the map. For example, you could place a command center for a zerg player without using a trigger. You can't place things over a start location though. :( The original patches are still in the zip file. You can place all the units first, place the start location away from everything else, save the file, then use the original patch and place the start location where you want it. The units from other races stay on the map when you aren't using the patch.
I removed 'StareditSECwads.zip' because the size of the file would be larger than the total size of 'StareditCwads.zip' and Stardraft.
