Hello,
I did some coding and this time I'm gonna release my unfinished work (executable+sources) instead of letting it rot away on my HD. I used Harteex's toolchain and his astrolander sources as a basis, so it compiles the same way as described in guide-how-to-compile-apps-for-dingoo-native-os-without-sdk-t814.html.
Maybe someone feels like finishing it or optimizing it in some way, it's a bit buggy and missing a lot... I also think it could run faster :/
If you just wanna check it out without compiling it, put the target.app on your dingoo and execute.
