Re: Cross Chase, New Hi-Res Game

Cross Chase is a game written in C with my universal library. The very same source code ( https://github.com/Fabrizio-Caruso/CROSS-CHASE) can be compiled for 200 different systems including the ZX80, ZX81, Lambda 8300, Jupiter Ace and nearly anything with an 8 bit CPU (consoles, hand-helds, calculat...

Re: Universal games with CrossLib - CROSS CHASE

@nihirash, no UDG and no hires, yet on the ZX81 and ZX80 due to the technical complexity in C.

I could attempt WRX hires because it is supported by Z88DK but I am not sure it is possible.

Re: "wall" game for the Lamba 8300 / Power 3000

Was my game (CROSS-CHASE) patched?

What was the issue? I can make a permant fix in my tool-chain so that future releases work on all Lambda versions.

Re: Cross Chase on Lambda 8300

Hi Maybe the game needs some tuning but keep in mind that you need to fetch the gun (shown as "!" or "G" or as a gun when graphics is implemented). If you get the gun, you have 3 shots that you can use against normal enemies, the skull and missile bases (of any kind). Use the gun against the skull a...

Re: CROSS CHASE

Thanks for testing on real hardware!

Could you make a video? That would be cool to prove it runs on the real ZX80.

The black screen can be fixed more easily.

The flicker is hard or impossible to fix in C.

Re: z88dk: Creating flicker-free animation on the ZX80

My game code does not do any floating point operations.
The problem is the complexity of the code (the cyclomatic complexity may also play a role).
It must be possible to implement a slow mode but I guess it would be extremely complex.

Re: z88dk: Creating flicker-free animation on the ZX80

Indeed, but this does not make flickerfree animation impossible.
It just makes it VERY hard. After trying many times, I have given up and settled for a turn-based version of my game, which is equally fun to play. This even convinced me to make turn-based versions possible for all other systems.

Re: CROSS CHASE

I have only tested the (turn-based) ZX80 version under the EightyOne emulator. It does seem to work but you get some black screens at start up. You just need to press some key multiple times. I will try to fix the black screen. All ZX81 versions are using whatever the Z88DK devkit produces, which, I...
