Re: another demo

when you start Eightyone you need to go to options / hardware, then on the lower interfaces tab make sure ZON-X is selected for soundcard.... you should also make sure you are using the fixed ( well better but not 100% ) version of eightyone that sirmorris fixed up.

another demo

As some of you ( well those that went to Mahlerts this year ) you may of seen my latest demo for 16K ZX81 with Zon-X it is a tribute to Bob Smith Who In my humble opinion has since the era of 3d monster maze written the best games for our humble machines. Game graphics by Bob Smith, Music by Yerzmye...

Hi-res not working correctly.

Hi everyone,

A plea for some German wisdom if you'd be so kind, Over at Rwap forum This thread.

Proteus has installed internal 32K ram modification, but has since removed the 7400 and made it 16K but still Hi-res does not work correctly.

Any idea's ?

Thanks in advance Andy

Following on in the text mode only another little program as a proof of concept.

The block graphic on the left is just some not very random crap based on the rom contents, it's purely there as a contrast to the vertical text scroll...

it's a bit poor quality, my video capture card doesn't like the Zeddy, so this is recorded on my camera, but the audio is direct.

P.s it works in the AY-fixed version of EightyOne as patched by Sirmorris

Thanks Bodo,

Yes there is some trickery with the Vsync, precise timing is of course necessary or else servere display disruption occurs,

I also used one of your very fine idea's : the stack :D

He He :D I've thought about this quite often, what is the most comon format for the turbo-sound files? STC's would be preferable because they take the least time for the player code per cycle, but 2 pt3's may be possible but it won't leave much time for anything else...

Re: New demo for unexpanded ZX81

@Bodo,

I said very much the same thing on the english forum, the core code looks to be around 58 bytes in length, so i think Bbock is correct about it been a simple automaton, probably depending most on what is already in the cell-plane ( screen memory )
