p.s.: the only exception is mentions of "even M1", which simply means that opcode fetching always starts at even t-state (not cycle!) in 128K.
not in "128k", but in some clones (with any k)

Re: Help with attributes and logical and (z80 assembler)

Thank you for pointing me in the right direction @MatGubbins, but not giving me the answer. That is a great way to learn. I was clearing the attribute memory, rather than the pixel memory! clsscr xor a ld hl,16384 ld de,16384 +1 ld bc,6144-1 ld (hl),a ldir ret clsscr ld hl,16384 ld de,16384 +1 ld b...

Re: ZX ULAX emulator

Oh, and i forgot to say it's best to enable the FULL mode (with PgDn key) right at the title screen and leave it (no mid-game pressing PgUp/PgDn). Well, unless you want to see some weird artifacts as the ball sprites in the 2D scene are xored over each other in different modes. :)

Re: Baddies who follow you from room to room

This is a good topic! How about ... Shadowfire (I am not quite 100% sure on it tbh) https://spectrumcomputing.co.uk/index.php?cat=96&id=4433 and its excellent sequel, Enigma Force (they definitely do as I remember in this case) https://spectrumcomputing.co.uk/index.php?cat=96&id=1634 Two class game...

yet another game looks as intended

Championship 3D Snooker was a horrible mess of attributes most of the time (except the very endgame when there were only a few balls left). Now i was able to fix both 2D and 3D scenes properly, also gave the balls more traditional colors. Check it out. Btw what snooker game (and any cue sport game ...

oh, and Spectravideo SVI was just basic MSX-compatible, was it meant to be its predecessor SV?

Re: 1980s / 1990s Computer with the best design and Potential

I don't see anything on Amstrad CPC that couldn't be done on ATM-Turbo. But not vice versa. So despite the gfx chip, the Spectrum line is more powerful than Amstrad line, even if we compare year 1992 directly (by that time, ATM-Turbo even had an IDE controller). If you're talking about "lines" then...

game pack update

Only one game now, but with diverse gameplay experience - Sigma-7 . Very complicated code with lots of attribute effects. I was even forced to poke one byte in the original Z80 code to get the perfect result, otherwise some wrong colors persisted under the sprites in the phase 3 (as background attrs...

Re: 1980s / 1990s Computer with the best design and Potential

I can't name a single 8-bit machine as having both best design AND potential. The most notable example is Enterprise being good design but born dead as a platform. Actually, i don't think any 8-bitter had much potential for further development, even the MSX. All of them, good or bad, were temporary ...

Re: Baddies who follow you from room to room

iirc enemies in RotW don't follow, they just continue walking till dead end

and in Bruce Lee it's more like a respawn, not a pursuit
