New ZX81 Games

GOL doesn't run, neither on an ZX81NU nor on the EO.

I played it continuously on EO.
And it loads on real machine.

and it runs on EO1.39

I have been playing with this Johan and I'm quite impressed. it was nice to see the gliders rush across the screen.
I did notice that it's not wrap a round screen when they meet the edge., is that by design or lack of memory?

Also your post says it "starts" with a simulation, I assume this to be a demo of some sort whereas when it loads all there is only a black screen and no demo.

runs OK on SZ-81 Eighty One and real zeddy no problems.

Definitely one for the simulation folder.

The screen has a LINEFEED which acts like a wall. So screen ends there. Wrap around would cost a lot of checks how to do that, so both by design and lack of memory.

When I start with an editable screen the cursor would start on a different position. I deliberately started with a filled screen and let the program clear the screen in 2 loops. Stopping the simulation always sets the cursor on the same position. Earlier version had a byte short and then the cursor was even different when you started or ended the simulation.

Was a nice job to fit in 1K. Latest version won another 4 bytes, but I don't have anything extra to add in 4 bytes.

GOL-Bugfree Works on EO (V1.23), but not on my ZXNU (>64K ram, Bigbang ROM).
Crashes after pressing 'Z'

Hi Siggi, which settings and ROM do you use on EOV1.23?

[siggi]

Same like my real Zeddies:

Only ROM-call made is a6e to copy the screen.
Rest is default display and keyboardreading from intrupt.

BTW I found 4 bytes and when I alter the cursor that is 5.

With these 5 bytes I was able to stop with CLS or stop and keep screen.

Release later.

The code of Bigbang rom and Sinclair rom is identical at that location.

That is why I now use A6E and no more 19F9.
According to Paul this part is in all ROM the same.
