How do you convert special calls with __thiscall or __fastcall from C++ into delphi? as far as I know, there arn't any declares like this in delphi.

And knowing I fail at asm, I tried manually calling it and it fails. >.>

I'm no Delphi expert, but __thiscall is actually used in classes, so you could just shove your hook in a class. No idea about __fastcall though.

I know that __thiscall is used in classes. So I decided that I should emulate the call with asm...

So mov ecx,[variable containing class ptr]
(pushes all the parameters onto the stack)
call function.

And besides delphi classes don't use __thiscall either. They just push the pointer as the first parameter on the stack
