Hi,
This is a wonderful project and I would like to know more details about why you have abandoned the support for RP2040 chip. Some reasons I can think of are listed below.

1. Lua overheads in calculations.
2. Memory limitations (If my understanding is correct, Pico-8 has only 64KB of memory addressing. If so why is it hard to fit in 264KB RAM that RP2040 has?)
3. Framerate issues?
4. Is the float point calculations slowing down?

I am able to render 3D model with 5k triangles on to a 240x240 screen. using DMA and other features of the chip and it runs at 17 FPS. I am not loosing my hopes . :)

Hello, not necessarily an issue. Just a note that the pico8 core that runs on the TrimUi had similar issues to the ones that you've described. Double Celeste characters, no music but sound effects. However, it has subsequently been fixed so the fix may also work for you. Here's a link https://github.com/liartes/retro8/releases

Also I have an Odroid Go clone, that utilises an ESP32. Do you think you code would work with the Retro-Go custom firmware by Ducalex? https://github.com/ducalex

This ia an amazing project!
But I found that DOWN KEY(GPIO0) doesn't work, I tried other GPIOS like GPIO13 23 35,it still don't work,how tho slove this problem?
I found the key setting in sdkconfig
`#

Controller configuration

CONFIG_GPIO_LEFT=13
CONFIG_GPIO_RIGHT=12
CONFIG_GPIO_UP=34
CONFIG_GPIO_DOWN=0
CONFIG_GPIO_A=32
CONFIG_GPIO_B=33
CONFIG_GPIO_SELECT=0
CONFIG_GPIO_START=0

end of Controller configuration`

And can this project connect to wifi and run PICO8 splore?
Thanks a lot.
