Here&#x27;s another [1] project that does VGA output from an RP2040 (the project also includes some game). There&#x27;s also some support for VGA in the pico_extras [2] repo.<p>[1] <a href="https:&#x2F;&#x2F;kilograham.github.io&#x2F;rp2040-doom&#x2F;" rel="nofollow">https:&#x2F;&#x2F;kilograham.github.io&#x2F;rp2040-doom&#x2F;</a> [2] <a href="https:&#x2F;&#x2F;github.com&#x2F;raspberrypi&#x2F;pico-extras&#x2F;tree&#x2F;master&#x2F;src&#x2F;common&#x2F;pico_scanvideo">https:&#x2F;&#x2F;github.com&#x2F;raspberrypi&#x2F;pico-extras&#x2F;tree&#x2F;master&#x2F;src&#x2F;c...</a>

This reminds me of the Uzebox [1], a video game console based on an ATMega644, but the RP2040 in this looks far more powerful at a glance. How far could this realistically be pushed?<p>[1] <a href="https:&#x2F;&#x2F;uzebox.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;uzebox.org&#x2F;</a>

The PicoMite VGA project does something like this as well but has the added benefit of having a very full featured BASIC interpreter built in.<p><a href="https:&#x2F;&#x2F;geoffg.net&#x2F;picomitevga.html" rel="nofollow">https:&#x2F;&#x2F;geoffg.net&#x2F;picomitevga.html</a>

OT but a question I&#x27;m curious about: what features would people who have a lot of experience with the RP2040 like to see on a successor?
