easmith Posted February 28, 2018 Share Posted February 28, 2018 (edited) Ok, after several false "final versions", here goes . A problem was detected when the ROM was played on real hardware , but that is now corrected thanks to DirtyHarry. The final improvement was adding a shield feature , which protects player for 1 second but now also drains power faster . Enjoy! It is simple shooter but pretty challenging I think. The sound could be a bit more polished , but for 5 weeks' work I am fairly pleased. Thanks to all that provided positive feedback and programming help, and for tolerating my many posts. I have been a bit obsessive . Would be interested to know if anyone beats it or if there is a demand for any cartridges.
