Re: Challenges for porting 'Thrust' to a ZX81

Yeah thats a good point Bobs - your game does show that its possible even for the low-res to work. I had always thought in my own mind the need to see whats coming below as you scroll down being quite inportant - the bigger ships, the less cavern walls you'd see. But I can certainly see how its stil...

Re: "Hello World" for pasmo & ZX Assembler 2 using MMCoYZX81

Moonlander in hi-res would be a great idea for a 1k game! One cool thing about the game Thrust, its been ported to the Vectrex (6809 assembly with some C) with sourcecode: http://www.emix8.org/static.php?page=VectrexThrustSource And also the C16 (6502 assembly) has been disassembled http://plus4worl...

Re: "Hello World" for pasmo & ZX Assembler 2 using MMCoYZX81

Thanks guys! Its quite cool how it all comes together!! I've also got an example from the original ZX Assembler manual where it prints stars on the screen working in pasmo! I even was interested in looking at why CALL 0808 prints a character to the screen in ZXAS 2, so looked at the ZX81 Rom Disasem...

Re: Differences between 'ZX Assembler' & 'ZX Assembler 2'

Hey XavSnap From the looks, your link is the original 'ZX Assembler' manual which is what I'm using. What I was trying to do in the above thread was apply that manual to 'ZX Assembler 2', as it handles some things differently. I haven't got back to trying to get those examples in the original manual...
