It is also casually mentioned that the TMS9918 inspired the VDP in the Famicom/NES but I haven't seen any direct proof because it also seems possible that the 2A03 was derived from Nintendo/Ikegami Tsushinki 'Namco Galaxian' inspired arcade board design notably used in Donkey Kong. It's an interesting thread and perhaps studying Galaxian arcade hardware and Donkey Kong hardware and contrasting it with the TMS9918 and 2A03 can establish some geneology for home and arcade VDP design in the early 80's
But it is clear that there was a pretty 'open source' attitude towards hardware IP at SEGA and Nintendo and elswhere in the early 80s.
My absolute favourite song is from Ninja Gaiden "Escape in a forest" (starts at 03:36) here: https://www.youtube.com/watch?v=MFoA0OICiB4&t=207s
Someone played that song with real instruments, and it's also amazing: https://www.youtube.com/watch?v=Arun9KuXImk
