The code

One listing per bank in src/pennantrace_pNN.asm (p00 to p15), assembled with pasmo, which comes out identical to the ROM: make verify. 100% of the binary is explained: 50,191 bytes of code and 80,881 of data. Of the 25,026 instructions, 43.7% are commented, and none of the 2,933 routines is below the comment minimum. Every bank with code is over 40%.
