the Delphi SDK works with Delphi 2010 but is for A7. I haven't updated the SDK for the A8 engine yet.

there are 2 ways to use the SDK
1 - use the sdk to write a DLL that your lite-c program calls
2 - use the sdk to write your program in delphi which calls the A7 engine dll

in my mind use #2, if you have delphi use it.
check the samples in the sdk to get started.
