Pupdate Although it’s looking ready to snow outside as I type, we’ve had some glorious summery weather in March, which means plenty of time outside running around for the boys. But the picture that grabbed most attention was this one: People thought we’d got another sausage dog, but it was just the boys hanging out […]


My original attempt at an RC2014 Mini driver started out as pretty much a copy of the gsz80 driver, with a find/replace of ‘gsz80’ with ‘rc2014mini’. But as the MAME team reviewed my pull request, they surfaced a bunch of problems. Firstly I didn’t have the correct memory map. The RC2014 Mini only has 32K […]


I mentioned in my previous post Grant Searle Simple Z-80 Machine on MAME that the gsz80.cpp driver was like finding a Rosetta Stone for MAME. In this post I’m going to go through it block by block to explain how I parsed it, and how it enabled me to figure out how to write a […]


In my RC2014 Mini on MAME post this was one of the things I was planning to try next, and once again there was an existing driver that had most of the pieces in place – evmbug.cpp implementing the TMS 9995 Evaluation Module (aka TMAM 6095). My first job was getting the existing driver working, […]

Pupdate As we neared the end of the month it was finally warm enough for the boys to walk without their coats, and whilst they might look cute and snuggly in the coats they seem more energetic and free without them. Pi Stuff – MWC Demo All of that time spent playing with Raspberry Pis […]


TL;DR Getting an RC2014 Mini working based on the Grant Searle Simple Z-80 Machine driver was pretty trivial, but it’s been enough to get me going with MAME development and persuade me to try some other things. Background I know there are already emulators out there already for the RC2014, I’ve used EtchedPixels/RC2014 a bit […]


TL;DR I’ve been wanting to try emulating some RC2014 stuff using MAME for some time, and I think I’ve found my way into it with the MAME driver for Grant Searle’s Simple Z-80 Machine. Background Back when I was making my TMS9995 on RC2014 system part of my adventure into the lands of TI-99/4A fans […]


I spent Saturday manning the @BrightonPi stand at Brighton Mini Maker Faire showing off various projects with Gareth James. It was great fun, and I really enjoyed talking to people about the potential of the Raspberry Pi. There were a few questions that got asked a lot… hence this post. The projects I was showing off […]


After getting MAME going on my Raspberry Pi so that I could play old arcade games. I wanted to hook up a proper joystick. Back in the 80’s I had the excellent and ubiquitous Competition Pro 5000. As mine (foolishly) got sold with my Amiga stuff I got one on eBay, and it came in […]


I grew up in the dawn of arcade games, and living at the coast meant that I had access to a couple of decent arcades where I could play all the classics as they came out – Space Invaders, Galaxian, Defender, Moon Cresta, Galaga, Phoenix, Star Wars, Tron and Tempest all stick in my mind, […]
