Re: DEVASM-Z80 - Cross Development Environment in Assembler for ZX-Spectrum based on PASMO

Distribution of PASMO without source is technically also illegal, since it's released under GPL.

Re: ChesSkelet: micro chess program - 363 Bytes

Excellent write-up, I'm thoroughly enjoying this. Gears creaking quite a bit in me ol' brain, but so far I could mostly follow your explanations.

Btw the most recent version of VTII is available at https://bitbucket.org/ivanpirog/vortext ... downloads/ . The above tutorial is for original VTII though, but it should be enough to get you started either way.

Re: How do I make background sound?

Ahh, background beeper music, the holy grail of ZX 48K programming :mrgreen: While the Joffa approach certainly works, it won't help much if you plan on making a 50 Hz or 25 Hz game. There is another solution, but it's so tedious that it has never been done. Ok, so your idea about dedicating half a ...

Re: irrlicht project live @ Ohrbit 2018

ZX beeper music, with a few TI calculator tracks and an Atari VCS tune thrown in. Style-wise it's pretty heavy, mostly metal and hard-rock, occasionally with some screaming v...

Re: Questions about FZX

Don't skip the position bytes. Pass them to the driver after you've passed the AT token. The way you have it now, the first two chars of "TEST" are interpreted as the position ;)

In other words, throw out the "or a, jp z,..." and you should be fine.
