I have very high hopes for this board, and have been playing with RP2350 with DVI out for a while (I have one of these on order but it hasn't arrived yet, but other boards[1] exist).
Emulation is a sweet spot because if you race the beam, there is no compositor latency. Basically every retro computer with less than a quarter meg of VRAM is fair game (whether a framebuffer or not).
I have a bit of time off this fall and intend to do some fun things.
