# W0lle :
- You can delete now the config.bin, it's not necessary to convert the config back to .bin once done
Seems like it may be possible to leave it as is?
I used PboView to open the characters pbo, then I opened the config.cpp file as is and went through and changed all M4AIM to M16A2. then I packed the characters folder ack into a PBO but when I loaded into the game editor to try it, all the units were still using M4s.
I'm quite confused haha. A step by step would be very helpful. I've seen some of the other posts on the BI forums and here but they dont make sense to me. Too many gaps in the explanations.
