How sad, replying to my own mail <_<
Oh well...
I have found the examples in the GAMEPARKDEV directory. However, there are some inconsistencies. Firstly in the text file describing each example there are no description of some of the files for example ex000 exists but has no explanation. Also in the API pdf it refers to these files by names like Ex_2_flip rather than ex002.
As well as this, there are no versions of these files to complie and run on the GP32, they are organised to be compiled and run on the PC. You can get them to run eventually by changing all C++ comments to standard C comments and renaming a few things.
Also, a lot of the comments are in Korean.
Does anyone know of any guides to these files in English? Any reference etc?
