Too much fun.

For comparison, here’s the FPGA version, using the GPU from MiSTer’s PSX with some glue logic for the bus.

I’m getting a kick out of both displays being FPGA-driven.

In case you were wondering, this is the performance of the DTL-H201A on the RP2350B. The unoptimized Beetle PSX GPU is fast enough for the tools meant for the artist board, but not a 3D accelerator.

Back in July, I reverse-engineered the Sony DTL-H201A Graphics Artist board. Now, PicoGraph has a new non-video-adapter mode based on that work: an emulated PSX GPU on the RP2350B that works with the original tools.

PicoGraph is now running on the PicoMEM2 board, with some testing in the wild.

One FPGA video card. Two monitors. Total debugger supremacy.

Really neat window into the design of the old graphics cores. Thanks
