Hello, I'm trying to test this code but I noticed that some important elements are missing, such as the sprite files. Would it be possible for you to publish them? Thank you.

@Zorglupy
On the Pico run make_sprites.py and s_inv_miss-py to create the binaries needed.
I also added a modified version for the Pico2 that removes the problematic RESET_PB() and changes the overclocking address.

@samneggs , Thanks for adding the missing elements 😉 I’m now able to run the program successfully. While exploring your repository filled with these great programs and strong educational value (especially the low-level optimizations using Viper, ASM, and PIO), I noticed that many of the programs have the same issue as this one — they’re missing key components (e.g., Centipede, Tetris, Hill Climb, Race Bots → sprite, texture, sound library, gfx library) that would allow them to run properly. It would be fantastic if you could also add the missing elements for those programs. A brief reference to the hardware and libraries used (e.g., GT911, GC9A01, etc.) would also be very helpful. Thanks again for sharing such interesting work!
