I'm compiling it from visual studio, that's why I mistakenly added audio.cpp to the solution, oops.
Console definitely says the system started and boot.rom has loaded, if I try and display the playdate fps from your code in the main loop, the fps does show up. When I click on the menu button, the option to reboot uxn is there.
One thing to note is that if I try to invoke the dispay fps api from anywhere in your code where it's supposed to parse opcodes to display pixels, then it never gets called. It's like it never finds anything to draw.
The boot.rom file I'm using comes from the desktop uxn files from itch, I tried a few roms, none of them shows anything.
