I don't know if anyone is interested, but I did a little Z80 programming project recently, where i made a small game that compiled onto 11 different computers and consoles, including the Enterprise...

It was really an experiment in multi-platform development more than a 'substantial game', but the game is free, and open source, if anyone wants to play it or use the code then they are welcome!

Great! Thank you!

If you like unique Z80 systems then also add Videoton TVC (hungarian brother of Enterprise)

That's certainly not one I've heard of... but I'm afraid I'm not planning to cover any extra z80 systems now, the addition of the Gameboy an Mastersystem were a cynical ploy to increase the popularity of my Youtube channel and game development ... so adding rare unheard of stuff won't help me in that goal!

I'm going to be sticking to my current systems for my Z80 for game development (though I won't do anything serious on the TI83), but I plan to start covering new systems using the 6502 and 68000 processors in my Assembly tutorials next year!

I don't plan at this stage to write any games that work on all CPU's, I'll just be writing tutorials mimicking the ones I'm doing now for the Z80.

I'll be using VASM in all cases, and I'll try to create functions for graphics and input that do the same kind of job in the same kind of way, but I don't see any realistic way of writing 'z80 code' that converts efficiently for a 6502.

Learning Z80 has made me interested in the 'competitor' of the 6502, and I think the 68000 give a fascinating insight into more modern CPU methods, so I want to start trying to learn and document those... I also have a nice japanese x68000 PC I've got my hands on, so that has been a big 'encouragement' into forcing me to start learning this stuff!
