Re: Arculator v2.0 released!

I am far, far, far from an expert, but it looks to me as if there might be some kind of threading issue at play. Some OSs are more tolerant than others of UI API calls being made on non-UI threads, and those 'closure_invoke' calls in the call stack would seem to suggest some kind of concurrency syst...

That is a real shame, the annotations really added to those videos and provided so much context. Looks like Youtube removed them permanently a year ago.

Re: Emulating (or obtaining!) an ARM Evaluation System

Thanks everyone for your replies. And B-Em does too. Again I am not sure how accurate the emulation is. I am also not sure what the benefit of making the emulation cycle accurate is.

Emulating (or obtaining!) an ARM Evaluation System

Hello all, At some point starting in the Summer I’m contemplating a project that would target the first ever ‘released’ ARM, specifically the one inside the ARM Evaluation System. However, this would entail either being able to accurately emulate one (and it would need to be cycle-accurate both with...

Re: Bouncing Basketball tech demo on the Acorn Electron

Until you realize that the Electron has an always-on interlaced PAL frame with two differently timed fields. And you have to find a way to determine which field is active. And you need 100% cycle counting in your timing critical code. ... sounds horrible but not *that* bad so far... And you realize...

Re: Publishing multi-part projects on github.

You could look into git submodules for this. They’re often used to make repositories that ‘contain’ or ‘link to’ other repositories. They’re not without their problems but when configured and used appropriately it can be the right solution to this kind of problem. I’d echo what was written above tho...

Pretty positive if you took a close look you’d be able to find some software in there that isn’t GPL and where the original creator still retains the copyright!
