Building a Psion/EPOC32 emulator

In which I build WindEmu, an emulator for the Psion Series 5mx (a PDA from 1999 running EPOC - the OS that would become Symbian), over the course of just over a week, without access to the actual hardware. Yet another cursed project.

I had never seen this before, even though it's from 2019. You can load the emulator in your browser and use EPOC32 as if it's running on the real thing, and I have to say it feel remarkably realistic for a project completed in a little over a week. Of course, it may have been tweaked and improved over the years since 2019, but I don't know by how much. The last GitHub commit was five years ago, so it seems there really hasn't been much public work done on it since.

An emulator like this is probably the closest most of us will get to the later devices from Psion, since as with all retrocomputing platforms, the number of working devices is rapidly dwindling, and prices for working examples on sites like eBay have gone through the roof.
