zombie666 v27f2 how to replace file

[mofrpg]

The map is encrypted
trigger encryption，Use different combinations of L and I, 0 and 1
The file cannot be replaced because the size of the map file becomes larger after the replacement……
Single player games are not allowed

Can anyone tell me how to solve the above problem
