Line 13:

Over the years, many individuals have attempted to reverse engineer specific parts of the WoW client. These are usually siloed away into individual IDA Pro databases, making them difficult to locate, and thus more difficult to make use of for the purposes of game preservation.

Binana aims to avoid situations like this by storing RE work as machine-readable code in a public Git repository. This code can then be converted/parsed/encoded any way we like, usable in any tool you care to add support for!

Binana is mainly targeted at version 3.3.5a of WoW. By reducing scope to a single version, the level of difficulty involved in implementing Whoa/Thunderbrew features is lowered significantly.

FunctionName1 11223344 f end=22334455 type="void __stdcall func()"

ClassName__MethodName 12345678 f end=23456789 type="void __thiscall func(ClassName* this, int32_t argument)"

</pre>

Our reverse-engineering tools cannot always detect the end address of a function (x64dbg cannot detect this at all!), so you should always give the end address of the function.

For Binana, the convention for the end address of a function is the address that's 1 byte after the last instruction.

For example, <code>0042830B</code> would be the end address of <code>WowConnection__AddRef</code>

<pre>

WowConnection__AddRef:

00428300 b8 01 00 00 00 MOV EAX,0x1

00428305 f0 0f c1 01 XADD.LOCK dword ptr [ECX],EAX

00428309 40 INC EAX

0042830a c3 RET

------> 0042830b cc ?? CCh

0042830c cc ?? CCh

0042830d cc ?? CCh

0042830e cc ?? CCh

0042830f cc ?? CCh
