Re: 1-bit on the Vtech Laser210/310 and VZ200/VZ300 Z80 computers.

Connected my little VZ300 up to the sound system in my ute, and away we go...

Ha, looks like you've got quite the collection of beeper engines on the VZ now.
I do listen to beeper in the car but I really wish it was as warm and sunny over here like in the first vid, haha.

Finally managed to get Dark Fusion working.
Seems to be nearly spot on from after listening to the MP3 of the original.

Apologies for the potato recording.

Phaser 3 engine is mostly working. This is Fase Dos and the other song (unsure of its name), both running on a real VZ300.
Please ignore the video display hashing.
I'm pretty stoked with the results considering that this is way beyond the original design capabilities of this computer.
There is something still not quite 100% right though, as can be heard in Fase Dos towards the end.

Good work! But indeed I think you've got a bug somewhere, sounds like several notes are missing to me.

Re: 1-bit on the Vtech Laser210/310 and VZ200/VZ300 Z80 computers.

I've finally thrown up most of my working ports for the VZ from both Utz's, Shiru's and Oleg's incredibly-skilled programming engines, of which, I am always in awe of. There really is only a few lines of code to change to make these work for the VZ computer. Of course, timings are out when you change from "OUT (C), A" to "LD ($6800), A", and I am always selecting one at random to try to improve the sound quality by tying to count cycles and improving the timings. But, at least they do work.

".VZ" is the VZ/Laser emulator snapshot file. These can also be converted into a WAV file, and loaded directly into a real computer.

Wow, what a massive package. Thanks a lot for all your hard work!
