For example, there is a game for Linux/Windows/Mac called SuperTux, but it is also being currently ported to iphone(Which i will buy). How does one do that? I am a noob dev who wants to make a little extra cash by porting small apps like algebra solving calculators, or port mini games for my personal pleasure. If that is stupid and illegal, just delete this thread.
Wrong section.. But for porting, you need to have decent knowledge of both languages (the language you're using for the iPhone app and the language of the original app). You should see the code in the original app and attempt to replace it with Objective-C code. Easier said than done, but you could always use C++ code or algorithms.
it is release in app store? what's the app nam? thanks, Vicinno, the maker of BA Financial Calculator
