Some private servers use 100.02 server, the client is 115.02, this is how to achieve

Mixing .gpks, trial and error.

RealEditor + TMM i guess, i didn't poke around too much to see how it works

How to skip client version verification?

How to skip client version verification?

The client/server need to be aligned on opcodes (codes used to identify packets during communication). If they don't align, the server will reject the connection.
Opcodes are different by version, 100.02 opcodes are different than 92.03 ones.
The best approach i guess, would be as argeus99 suggested to mix the 115.02 gpk with the 100.02 ones

EDIT: Also, some opcodes may exists in 100.02 and not exists in 115.02 (same applies as some in 115.02 not in 100.02), meaning that even the server don;t know how to handle them
