I was able to run it with OpenMSX. It uses the

Konami 8K with SCC bank switcher.

I wrote my own. It's more work, then I can port games more easily to all the platforms I support. I can also make adjustments for the performance needed for this game. Besides, it's interesting learning about different platforms.

I did it that way originally, but I felt that it pause loading the new image on the next level interfered with the flow of the gameplay too much, so I changed it just load on start.

Yes, I've added it in this version. It's great to see someone interested the Sort M5

Try it now. It woks on OpenMSX now, but I don't have real hardware.

Thanks, I was adding the wrong file to the package. I should work now.

Probably not POP, since it's about 200K and requires a bank switching cartridge. But I can look at the possibility of supporting NABU with some of my other games.

Oops! Thanks. I forgot to add it to the package.

POP is a big project. I'm working in it now, but it will take a few months to complete.

SG-1000/SC-3000 is available in the download. This is my favourite platform as well.

Thanks. I always forget to test the game over part. I've updated it and it should work now.

The C64 port has been added. Let me know what you think.

I fixed the joystick for CPC - that was an oversight on my part. I've changed the background to grey - I originally avoided it since grey is quite dark on the CPC.

I'll have to look into what changes need to be made to work on GX4000.

Thanks. It's written in C using sdcc. Some plaforms, such as Gameboy and ZX spectrum, needed some Z80 at the video rendering level to get it fast enough. I've written my own hardware layer for each of the platforms. It's been interesting getting to know each platform.

I'm having a look at the possibility of C64 support. It may be some months.
