Understanding Maplestory and how amazing it actually is from a average gamers view.

The PQs/events for BrazilMS Binaries are encrypted in BMS .WZ img format, not many have seen how it was coded though except for the NPC/Reactor scripts [.s format].
Although a couple of people have the tool required for decryption. Snow, Bui, etc..



No, almost every PQs/Events are poorly coded.
Most of the so-called "developers" (Not every one of them) for OdinMS have zero knowledge in cleaning up code, cleaning up references [memory issue] but by copying + pasting from the already scripted ones. As long as it's working, they are fine with it no matter how badly coded it is.

Vana is an exception since it's well maintained by dedicated developers.

I think my IQ dropped in about 4-5 points while reading this.

1.WZ files hold the details about maps, mobs, npcs and all that. The actual functionality of the PQ is coded mostly on scripts and partially on the server itself.
2.The tool required for decryption? The scripts are text files, the WZ files are... well, simply WZ files, and the server binaries have their PDB's with them. What more can you ask for? the source code? you got most of it anyway.
3.Are you talking about OdinMS's developers or the script kiddies that think they are cool because they created an NPC?
