itch.io

The layout is because of the Interface II support.
I honestly don't hink that it is really playable without joystick.

Found no way to detect Kempston automatically and I don't want to add a UI. Furthermore there are Kempston interfaces with more than 1 button around, which are impossible to distinguish. So, also the buttons would require configuration from the UI.
So, not much hope for the Kempston unfortunately...

I will look into it, but AFAIR the Kempston was 1 joy port only.
Give me some time...

I didn't expect such a great response. Many thanks for that.

If you're interested, I could keep a hiscore table here on the site. Just add a photo of your score in the comments. If there are enough entries I assemble something.

Tranks for the video. I'm glad to see that you have fun with the game.
A tip: To revive your wingman you have to collect (touch) the "+1".

Great conversion!!

I'm using it in a MAME cabinet and I would also like to handle the hiscores (MAME can readout the values of certain addresses and store them in a highscore file).

For this to work I would require the address where the highscore is stored.

Could you maybe post it.
