Aegean Help needed!

[Jojo]

Hi guys.

I want to make some changes to Aegean V4 Theater.
1) Change country names
2) Change country flags
3) Change UI screens
3) Change the available planes listed in TE.

1) I totally don't know how...

2) With the help of 611-Eagle (thank you man!), I "unziped" the main.idx file. I found some flags, with the names SMFLGS_Country (USA, NKOREA etc). If I change these files, will the flags be different? Or I have to change other files too for the flags?

3) I 've read the PMC Wiki but I don't know some stuff. What is the dif between 64 Segment and 128? Which is the right guide to follow?

4) I 've found teplanes.lst, in Campaing folder, but I dont know If it's the right file. I don't want to mess up the db.

Thank you guys!
