got a VERY big PlayStation 1 in the mail today, the original board for the first versions of Beatmania IIDX!
it plays videos by controlling a full-ass external Hi-Fi DVD player over a proprietary serial link, muxes that output back into the video signal, loads the game through a SCSI CD drive and gets its sounds from an IDE hard drive... somehow it all still seems to work after almost 25 years!
also contains two optional patches I used to make it build at all on my Fedora setup, since for some reason they put the FFmpeg includes in /usr/include/ffmpeg ¯\_(ツ)_/¯
@nafmo I would never want to take the joy of ffmpeg porting work from someone, so I'll just quietly note that I posted my patches further down-thread too :)
