Hello guys, ı have been trying to change some of the loadouts of game classes such as rifleman, grenadier, and medic with a different weapon that is already in-game. How can I do this? Whenever ı edit the regarding config.bin files with Editpad+ it just doesn't work, it gives me out of memory errors and it doesn't really work. Am ı missing something or just doing it wrong please show me the true way for config_men loadout customization. Please help me to fix this annoying issue, ı just want to spawn "rifleman" with m4 without needing to write any codes to the Initialization sector.
