The ZX Spectrum Analyser is a powerful tool that allows ZX Spectrum games to be analysed, disassembled, and annotated, to discover how they work.
https://colourclash.co.uk/spectrum-analyser/

It's a seriously cool tool with lots of ideas to borrow from, I also see many ideas I had over the years have already been implemented, so I take that as validation, and it helps me identify what works and what doesn't without even having to write any code.

En Chromanoids el profesor Williams fue capturado por alienígenas.
Su invento más brillante, un limo pensante llamado Oozi, se abrirá paso absorbiendo a cualquier enemigo que se cruce en su camino para rescatar a su creador.

What sorcery is this... a 3D platformer on the ZX Spectrum? 😮

Cubix (2025), an entry in the https://yrgb.org competition.

Screen recording of Cubix, showing the transition from a 2D platformer into 3D. Sure, it's monochrome, but still impressive.

As I understand it, all "stretch goals" have been unlocked, including the ZX81 core, the Amstrad CPC core, Doomdarks, and Monty Mole.

Olifiers corrected a previous message he sent where he had said we'd be getting a CPC 464 core. That was incorrect, it's a CPC 6128, "with good prospects of becoming more" in Henrique's own words.

zen80 update: improved tests

*** Apart from the already substantial unit tests, we now have two additional and rather stringent tests:***

  1. This test loads the ZX Spectrum 128 ROMs (0 and 1) and run that machine's initialisation process. Then it shows a statistical analysis of the instruction coverage that's been executed during rom initialisation. (total percentage of different opcodes executed for each instruction group)

  2. The second big test implements traps as barebones CP/M shims, loads ZEXDOC.COM and runs its extensive stress test (this can be long).

Work is ongoing to support ZEXALL.COM as well, an even more stringent version of zexdoc that also tests undocumented registers and quirks of the Z80, one of the hardest tests known. This will be next, after I'm certain that this passes all ZEXDOC tests without a hitch. So far so good!
