As some of you may know there is a public software client at [login to view URL] which allows people from all over the world to download it, install it and run they games trough it and play with other people via Local Area Network.
This is done by performing hooks in the game process as follows:
========================
[2060] [login to view URL] -> ws2_32.dll->sendto || 0x75723AED -> [login to view URL] [0x100036D0] || Inline - Relative [5 bytes] [JMP &]
[2060] [login to view URL] -> ws2_32.dll->WSARecvFrom || 0x7572418D -> [login to view URL] [0x10003960] || Inline - Relative [5 bytes] [JMP &]
[2060] [login to view URL] -> ws2_32.dll->connect || 0x757248BE -> [login to view URL] [0x10002F80] || Inline - Relative [5 bytes] [JMP &]
[2060] [login to view URL] -> ws2_32.dll->recvfrom || 0x7572BF39 -> [login to view URL] [0x10003AD0] || Inline - Relative [5 bytes] [JMP &]
[2060] [login to view URL] -> ws2_32.dll->gethostbyname || 0x75737133 -> [login to view URL] [0x10002940] || Inline - Relative [5 bytes] [JMP &]
[2060] [login to view URL] -> ws2_32.dll->WSASendTo || 0x7573ADC4 -> [login to view URL] [0x10003B40] || Inline - Relative [5 bytes] [JMP &]
=============================
I am currently thinking that recvfrom and sendto are the most important but i may be wrong [login to view URL] hooking IS the key.
So my mission for you is to be able to build/perform such hooks which can emulate LAN gaming over the internet, I am thinking this will involve server building which you should be able to do too. If you don't have much information about Garena, you can look for information related to Hamachi, it's just the difference that Garena is huge.
I will need to have access to the source code you build in the project, being understandable easily, the server part should be better to be done with sockets instead of Indy (the server should be Windows compatible, Linux is unwanted currently).
Also if possible you can expand this project to a website with (my)SQL system via PHP which can manage accounts and stuff, but this is still not planned.
Please excuse me for my bad english, kind regards.
My skills suits this project best way!
I'm a professional software developer and very skilled in network protocols. I've completed a few low-level socket processing in Delphi and I fully understand what you need here.
