  I use klm8g1getf. It’s 8GB and about $5 from LCSC, easyEDA has the footprint and symbol. I run mine at 52mhz, 4-line mode. I’m able to playback 20 stereo wavs at once @44.1k 16bit. Writing is a lot slower but 8 should be possible. I wrote my own flat file system to prioritize speed, all the standard file systems will slow you down a lot, as far as I could find, sequential reads and writes are much faster, and most file systems don’t do that. https://github.com/marchingband/wvr/blob/main/src/emmc.c

  GFX is a device independent graphics library primarily intended for IoT MCUs but not limited to that. (by codewitch-honey-crisis)

  I do something similar to VSPI in my Arduino based drivers for my htcw_gfx library.
