Happily... the project is BACK ON! ^_^Y But here is the question... were there ever any "true" 2 player joystick games on the #AcornElectron? I remember er... Dogfight on the BBC Micro was fun for 2 players... is there an Elk version? any other games? Any that utilised analogue?

So discovered that Arena 3000 at least on the BBC supported twin stick for single player. One for movement, the other for fire direction. game is on Elk and supports joystick. Probably 2 but I didn't check it yet.

Yay! Have just successfully run this on my simulated logic gate CPU on my phone, at a whopping 1Hz! Machine code on left, address middle, then assembly code, then comments.

A bit work in progress but I've been gradually building/simulating a Ben Eater CPU (from logic gates) on my phone for a while and finally got to the bit where I get to decide on the instruction set. It's still subject to change but was fun coming up with it. Hoping I won't miss a LDV instruction!

Finished adding bank switching at the weekend so instructions 10 and 11, UBN and UMA should in theory now actually do something. Still needs proper testing though, although preliminary checks by manually setting/clearing corresponding registers looked encouraging.

You are up to date.
