Trevor 'Smila' Storey did the box art AND game art. Truly superb work!

OK, I will sort out an 800 x 800 image for you

It's a PAL only game I'm afraid, hence all the issues on NTSC hardware.  It runs beautifully on PAL hardware however and I've never had the game crash once.

Sure, what size do the images need to be fit the frontend you are using?

If you are using the Winvice C64 emulator you may need to turn true drive emulation ON for the disk menu to work (although separate .prg files are also supplied which are very easy to load).

The code is for the end sequence which you need to load separately from the disk image.

Hi, this a Commodore 64 game so you will need a C64 emulator to run it on a mac.  I recommend the VICE emulator which you can download for free here:-  http://vice-emu.sourceforge.net/macosx.html

No need for a demo, the whole game is available to download for free on this page and it can be run in a C64 emulator

Yes, an NTSC compatible version is now available in the download bundle.

Yes, the game is compatible with the sd2iec device.

Hi, you could try right-clicking on the game .exe file and then change the compatibility mode for the file to an earlier version of Windows. Win 7 or XP. Also, have you tried changing the graphic option from Direct X to Open GL? And you could also try running the game in a Window rather than full-screen. There are loads of options available so hopefully one should work for you. I've tested the game on two different Windows 10 PCs and the game worked with no problems.
