nao posso dar informaçoes pois nao entendi absolutamente nada =p mais ta ai como objeto de estudo.

[hamiltontsz]

pelo que vi isso seria para adicionar novas Jóias no GameServer..... muito bom para estudo.

[Jamel]

não é pro game server isso, é pro main ^^
no GS a auteração é facio de ser feita

[levelx]

é para main 1.0S mublue^^

[KromeSykes]

esse source adiciona 2 jewels

Jewel Of Luck e Jewel Of Skill correto?

tenho que dar hook nessa dll no main entao, mas qual procedimento para o gs ler isso? se alguem puder me explicar.

Serve para qualquer main?

[andziin]

achando os offsets corretos correspondentes ao seu main sim server em qualquer main
ja no gs é chatin pq envolve umas funçoes

[KromeSykes]

alguem poderia explicar quais funções tenho que alterar ?
