Meteor Storm is done, so time for a new project. Thanks to the replies for your ideas I am thinking of a hires racing game based on RACE of the videopac-console http://www.old-computers.com/museum/software/philips_videopac-c52_g01_1.gif You need to overtake a number of cars before time runs out.

With partial decoding with the 7432 you can skip the 74138.
Did the same with my zx-pc interface.

New rex and food graphic

Hmmm - looks more like a fly or frog or a combination of both. Anyway somehow frightening. :mrgreen: Yeah, the frog came also to my mind. Base was when Rex comes towards you and opens his mouth. I gave him a few of pointy scrubs on the head. The graphic has the head, two small claws, the big feet a...

Altered Rex and hatman Size of screen is here BTW 20 bytes.
4 bytes per depth and 4 bytes for the end wall or passage.
UDG is placed during display.

I was thinking of a small altered plot for the game. Our highhat boss sometimes has days with no visitors, but Rex must be fed. So he needs to enter the realm and seek the food before Rex eats him.

Is this REX scary enough for 1K?
Already a small display of the screen. Must be centered etc.. Also deeper view possible.

I am getting nice mazes. The mist of time only needs a second to generate the maze.

What if you would connect the inputs of the 74ls32 direct to the inputs on the 74ls244?
I think it is possible when set correctly to eliminate the 74ls32 from the circuit, lowering costs even more.

Edit: you need an adressline and read.
With 2 diodes and a resistant you can built 1 or-gate too.

I have an idea and first results are nice.
Generator app. 100 bytes without mazedata. Total will be app. 200 bytes.
