The cycle accurate assembly language has enabled a number of timing sensitive FIFO data processes. What had to be done with FPGA's before has some limited support with PIO. I hope RPI increases the number of instructions and simultaneous running PIO machines in the future.
Talking about RP2040 powered controller firmware. GP2040 is an amazing project, which is used a lot in the Fighting Game Community where custom controllers are common. https://github.com/OpenStickCommunity/GP2040-CE
