found my mistake. I connected pins 2->3 and 3->4, making them all the same input. It should have been 2->4 and 3->4.   Will try again with it corrected.

It really doesn't matter at all.

Check whether when you short both 74LS02 inputs, pin 5,6 to ground, the CPC freezes.
You can add a second gate to the output by connecting PIN13 to Pin1 and pin11,12 to the group of pin2,3,4. 74LS02

If this does not work stably, we will add support with a diode pin 20 to pin 24 as before.

Having a dislike of Mode 0 and its garish colors, I liked both this choice of mode 1 and the melancholic color palette.
I'd like to see more of this style in future.

For years we've ben exposed to flamboyant, unplayable, low resolution mode 1 games (with no music) as a pseudo-remedy to terrible speccy ports (which stand on the other end of the spectrum*). I feel both extremes were terrible.

*yeah, spectrum

I'm not understanding your post? Mode 0 colours are not garish, they are the same as mode 1 colours except there are less colours available in mode 1.
Low resolution mode 1? It's the same resolution as the speccy in terms of pixel size only the CPC is higher resolution simply because the screen size can be larger on the CPC?

As I said, it was a typo. instead of mode 0 I wrote mode 1 so my argument became stupid.  Of course you're right my friend. Cheers.

Sorry, typo. This should be
"For years we've ben exposed to flamboyant, unplayable, low resolution mode 0 games "

Please ignore 2x green hooks on Z80. Those are from our previous test and not connected to anything.

All clips are connected when I power on, including the pin1 LS244->R143.

Occasionally on startup I get the white screen and black border, like the Z80 didn't halt. Other times the screen remains 'dead', so I continued.

I checked Z80 IORQ/RD/WR, LS244, and R143 for hi/lo, and they were all correct when reading A0-A15. If not correct values then I powered off, waited 5s, and powered back on to try again.


I took GND/+VCC from IC108 because the pins were easiest to connect hooks to.

A0-A15 all hi.  Still possible that I am doing something wrong, but it feels like I checked everything twice...

Are RD/WR/IORQ all Z80 pins?

You are no longer allowed to ask such questions.

Signal name is constant.

😆 Good answer. I think I am still learning that the state is constant across the board. No co-processors, etc. I sometimes found pins with the same name but on different ICs, and not sure which is the 'right' one. Now I know that there is no wrong answer.

Have too many joins. +5V should join one wire near Pin14, one hole above. Groung one wire near Pin7,one hole under.

I found my mistake. I connected pins 2->3 and 3->4, making them all the same input. It should have been 2->4 and 3->4.   Will try again with it corrected.

Please, show me photo of all setup.

It seems difficult to show everything in enough detail, but I will try (in a separate reply).

It's a fantastic game.
One of the best shooters ever released on any 8-bit-machines, technically and optically impressive.
Very
Congratulations to abalore, TotO and everybody envolved in the making.

If there is any chance I would like to order a cartridge.
