This is a really simple plugin made by request that loads configurable map specific starting credits from an option in ssgm.ini. If it doesn't find starting credits for a map in that INI it'll load the starting credits set globally before the plugin loaded.
<iran> there's an issue with the renegade client, if you hold 'L' it'l ldisplay the starting credits set on the map that the client joined, even after gameover'ing
Install the SSGM plugin like you would do normally and add the following to the bottom of SSGM.ini:
[MapStartingCredits]
C&C_Walls = 100
Add an entry for every new map, pretty simple.
