Ok, I have many saved games, and most of them are useless. How can I delete them? I have many Super melee! teams that are useless too. Can I delete them?
But how delete team which were already when the game was installed? Are they coded into game exec or something?
Yes, the built-in teams are included in the game executable. The easiest way to remove them involves modifying src/sc2code/melee.c and recompiling. I don't think it's worth the trouble.
The included ones are in the code because the game (3DO version, which UQM is based on) had to entirely run off of CD and have very limited save RAM to use. Add in teams were stored in save RAM but the built-in were loaded from the disc.
Yes, this is my theory even though a team save is only about 70 bytes big.
Perhaps future releases could be changed to create the team saves upon initial startup (much like it creates the .uqm folder and associated config files) and this would allow users to easily remove unwanted teams from their list.
