Everything you hear here comes from running the cartridge's own sound engine (suena_el_cuadro, 0x49C0, and pide_pieza, 0x490C, which hands it the voices; the interrupt calls it) on an emulated Z80, frame by frame at 60 per second, just as the game calls it. What the engine writes to the PSG is turned into sound with an AY-3-8910 (tools/musica.py). Each MP3 is the whole piece up to where it starts again, plus 8 seconds of the repeat fading out; those that do not repeat end where the engine ends.
The PSG writes have been compared frame by frame with those of openMSX (C-BIOS MSX1 japonés). In every frame the PSG ends up the same:
The timbre is not checked: it is a textbook AY-3-8910, not a recording of the emulator. The probes are tools/omsx_psg.tcl and tools/coteja_psg.py.
pide_pieza takes the number in A. Low numbers are effects and from 0x9D up there is music. Each voice takes fourteen bytes from 0xE010 and 0xE03A holds the copy of the PSG mixer, which start-up leaves at 0xB8. On the last frame of each long stretch the check differs because the game asks for the piece again. The tracks marked «in the table» are in the track table but no routine asks for them with an ld a; others, minutes long, are left out.
