>and extracted the internal ROM of the SAA-5050 Teletext chip used on Philips P2000T/Acorn System 2/BBC Micro
Holiday present now in source code in time for next official release.

Replace dump of SAA5050 internal character generator ROM with verified copy from decap. This also matches the Signetics and Mullard SAA5050 datasheet pixel listings. [Sean Riddle, ClawGrip, The Dumping Union]
I wasn't familiar with the system since it was more of a Europe region product, but a former coworker from long ago fondly talked about some of the games of the system. I didn't know if there were any other emulators running these games so I didn't have an answer for him at the time.
There's no chance of that thing being emulated properly until someone traces out the rat's nest of wires and produces a schematic. There's just too much guesswork involved otherwise.

The main BBC emulators are B-em and BeebEm, they're dated but are seeing some recent development. For quick gaming in a browser take a look at http://bbcmicro.co.uk/.
MAME has improved a great deal over the past couple of years, but still has a little catching up to do. It's certainly more configurable and supports many more expansion devices than other emulators though.

That's a bummer I didn't have links for Thomas way back then around 2004 or maybe it was early 2005. I didn't follow MESS and or computer emulation including DOSBox since I was following MAME much more at the time even though MESS was emulating the stuff MAME was emulating since MESS incorporated MAME code when official releases were out.
His [Thomas] interest was in computers rather than arcade games and his main interests would have been anything related to BBC products instead of Apple/IBM/Commodore products. I wish I had an answer for him back then. The job was a temporary job for me and I didn't see anyone after job was completed. It used to be in a small industrial area, but had been rezoned and houses are now in place in what used to be a former industrial zone.

Kudos to your work over past few years. If former coworker [Thomas] caught your work and all this today's emulation progress was back then instead, you'd made his day.
