Shinobi MSX:

It looks like if you POKE the characters "GRUTS" at address &HBFAC before loading the game, you'll get 128 lives and will see a greeting to the developer's girlfriend.

Been doing some #Z80 silliness on the #ZXSpectrum

I drew a boulder graphic which falls from the top of the screen to the bottom starting at random positions at the top of the screen.
I may turn it into some kind of game where you dodge the boulder but don't hold your breath.

The lesson for today is that when you are bringing up a new design that you should check basic things like the clock frequency early on in the process.

Also learned that a 10MHz #Z80 clocked at 30MHz is unstable.

Website update.
More videos and community links added to my site covering the hardware I've produced for #RC2014 and compatibles.

Cidco MailStation as a Z80 Development Platform

https://jcs.org/2019/05/03/mailstation

Wooo, first Rust macro written...things continue to progress. Still need to figure out exactly how I want to represent the `F` register though.

What do you do this Sunday? Me some Z80 ASM

So, making slow progress as I learn `rust` things. Instead of going with my usual `union`/`struct` combination in C, I'm resorting to not overflowing/underflowing primitive types and doing things more safely. This snippet of code took far longer than it should've, but it gets the job done.

Ein Bauarbeiter gegen Aliens? Auf dem CPC ist alles möglich!
„Brick Rick“ ist ein charmanter Arcade-Platformer mit 50 Leveln voller Action, Retro-Feeling und Ziegel-Strategie. Entwickelt von Juan J. Martínez – erschienen 2025 bei poly.play als liebevolle Big Box Edition.

I Ported SAP to a 1976 CPU. It Wasn't That Slow

It's 5 years since I released my first peripherals for the #RC2014 ecosystem, so have £5 off each of my first releases from June/July 2020!

SID Soundchip Interface
- Use the legendary Commodore 64 soundchip in your setup (or modern replacement SwinSID or ARMSID). Also incorporates 50/60/100Hz Interrupt Controller (useful too when using other soundchips for timing playback code.)

Graphic OLED Interface
- Add an easy to use 128x32 pixel graphic display to your setup.

All the info / order / see what else I've released: https://2014.samcoupe.com

Other RC2014 peripherals...

- *New for June 2025* SAA1099P Soundchip Interface.
- ZX True Tone (ZXTT), add-on module for Ed Brindley's YM/AY soundcard so it's clocked at the exact same frequency of the 128K ZX Spectrum so speccy tunes are pitch perfect.
- ZX-RC Bus Interface, to use RC2014 I/O peripherals with the #zxspectrum
- SAM-RC Bus Interface, as above but on the #SAMCoupe

I don't know what the hell is going on with SDCC ... but for some reason its shitting itself and eating both
\n and \0 characters in my strings at random.

A compiler should never optimize constants.

It's not just the #SAMCoupe I develop for, with several hardware releases for the #ZXSpectrum in recent years too! I've now launched a dedicated page specifically for them with info/pics/videos and to easily purchase.
