Open questions

What is not settled.

The check against the emulator

No picture has been checked against the openMSX VRAM yet: they are all drawn from the ROM, without that proof.

The bosses of ruins 1-4

Types 30 to 33 only appear in the lists of ruin 0. What creates them in the other four has not been found.

The sprites

The items

Item class 6 (p01:758C) has no known loader.

The sound

Bank 13 is commented at 27.7 %. What it writes to the PSG is checked against openMSX; the timbre of the AY used to make the MP3s is not.

Data with no reader

18 blocks, 132 bytes in all, that no instruction points to.

Texts not yet extracted

STAFF and THE END, in bank 4.
