thanks for responding, I am referring to running the game on the Miyoo Mini Plus handheld emulator using the Fake-08 core (which itself is being managed by Retroarch i think)
I realized it is actually working and to get it starting properly I just need to load Retroarch and do a 'restart game'. Then it loads to the title screen as it should.
That said once is loads it shows a mouse cursor but no way to control the mouse cursor using the miyoo dpad or buttons. Usually one can remap the inputs in retroarch but it doesn't give any way to remap mouse.
I realize you didn't build this game with this handheld console/emulator in mind so not expecting you to give a solution. In fact big thanks for making these great games!
I am sure there are other ppl than I who would also love to run your game on it. Having slipways running on such a pocketable device would be awesome. So in case anyone else knows how to get the mouse controls working for slipways on a MYM+ let us know! :)
