>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.

2018-11-13

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]


src/devices/video/saa5050.cpp

ROM_LOAD("saa5050", 0x0140, 0x03c0, BAD_DUMP CRC(6298fc0b)
ROM_LOAD("saa5050", 0x0140, 0x03c0, CRC(201490f3)

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.
