Yes, that is already supported. The library itself doesn’t impose any limits on resolution or color depth, as long as it fits within the hardware constraints.Would it be possible to support a 640x480 RGB332 8-bit colour depth frame buffer ?
The only reason the earlier example used line-doubling from a virtual 240p buffer was that the code was derived from my other Neo Geo → digital HDMI mod. The current example, however, outputs from a virtual 480p buffer.
I personally avoid holding entire frame buffers in memory due to RAM limitations. The Pico wasn’t designed to handle large buffers efficiently and also lacks sufficient SIMD instructions to make that approach practical.
