- test all examples (including imgviewer, assembler and petaxian) before release of the new version
- simplify cx16.joystick_get2() once this cx16 rom issue is resolved: https://github.com/commanderx16/x16-rom/issues/203
- improve counter vars creation in repeatWordCountInAY() and repeatByteCountInA() (asmgen.kt)
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
- get rid of all other TODO's in the code ;-)
