People are making games on RP2350-based cartridges for Famicom lately, and they look like games that could never be run on Famicom. That's because they're basically RP2350 games that use the Famicom as a display.
...Interesting but not exciting for me.

Did you know that an RP2350 microcontroller chip can output 640x480 video at 60fps? If you've got a Fruit Jam, try the demos at github.com/raphlinus/vi... (the v0.1.0 release has the video assets).
A lot of stuff came together for this demo, including inventing a new image compression scheme and

But how about making multi-screen games ?
For example, three Famicoms, each running a RP2350 cart on a separate screen, with a communications bus running between them to sync them all up.
That could be pretty cool - something like 3-screen Darius on Famicom.

RP2350 PiZero用のハット？シールド？を作ってみた。
HDMI/SD/USB(KB)/I2C/SPI/JOYSTICK全部込みで最小サイズのPB-1000エミュが動くよ。
MSXエミュとしてもかなり小さいけどMSX0があるから最小ではないかな。
これは基板作りたいかも。

Buttons, display and audio all running together on an RP2350 board is when it stops being parts and becomes a game. Is the sound coming off PIO or plain PWM?
