I checked yesterday. The joystick works, but the program continues to hang at the beginning of the cave :roll:

For me, the game hangs in a cave. If I understood correctly, then the zxpand joystick function does not work yet?

Re: If you like your submarine simulations fast, arcadey,...

There is some cheat-style help for those (like me!) that don't do games very well. Pressing 0 during play will toggle infinite lives. The zone last reached is stored in ZXpand's EEPROM along with the high score when the game ends, and you can skip levels you've already completed by pressing 1 durin...

Re: Hacking games to use ZXpand/Chroma/Other joystick

Your poke finding techniques should be a good place to start. As would address 22411 ($578B) which is the entry point to the machine code from the BASIC loader. It looks like a nicely structured program. disass.png I'm guessing that one of these calls would be for reading the keyboard, one for upda...

Re: ZX-IDE Tutorial for programming assembler and ZX BASIC

Hi.
Is it known problem, that when trying to load a program with a .p extension to a ZX IDE, the disassembly does not take place? I tried loading different programs with the same effect. Maybe I'm doing something wrong?

Re: Hacking games to use ZXpand/Chroma/Other joystick

Now it gets interesting. Here's a little program which is a proxy loader. Copy SCRMPAT.P to your SD card, making sure that SCRMBL81.P is in the same folder. LOAD "SCRMPAT" and ... scramble loads! The loader is not modifying anything yet. But it will. How it works: The patcher sets memory configurat...

Re: Hacking games to use ZXpand/Chroma/Other joystick

Thank you sirmorris for these tips. I'm going to try it out. Next game I will try to rewrite myself, but do not offend as I asked something. ;)

Expanded games ?

I have a question:
I am not yet proficient in the subject ZX81. Are the ZX81 an expanded game that picks up additional levels from the tape, as does the Spectrum? If so, what kind?

Re: Hacking games to use ZXpand/Chroma/Other joystick

Zx81 was my first computer in 1988 but i did not have access to the programs and i did not know anyone who would have the same computer. Then I quickly switched to the Spectrum. I never met the Z-80 assembler thoroughly. Sometimes I fumbled in the game code on the Spectrum. Sometimes I was able to f...
