@manawyrm UPDATE: turns out the hang was because I used the wrong DMARS selector (I geninuely forgot each DMARS field held 2 RIDs!) It now works (mostly) fine on fx-CG50/G90+E (except for audio playback speed, but that could likely be fixed by using a better value for the SCIF's SCBRR/computr it on the fly)
