WIZARD: LEVEL CALLBACK EXCERPTS

Addresses below refer to each separately loaded LnnT overlay at $C300.
Player and thief collection call $C376 after the configured treasure patch, with X as treasure index.
Reachable instruction excerpts follow; shared engine routines remain in the main Source tab.
These traces describe code responses, not complete player routes or puzzle solutions.

LEVEL 07: Simon Says (display level 08)
Nonzero low color nibble at $D832 selects BEQ at $C38C: matching the remembered
symbol is safe. Black selects BNE: a different symbol is safe. Failure sets
$C02A, but both paths still update the next instruction and its color.

X indexes the treasure slots built by $7BAA. $C400+X gives the collected
symbol; $C410+X supplies the next requested symbol. The callback copies the
latter to both the visible $C445 and remembered $C35F. The low two random
bits select colors black, white, light green and cyan (0,1,13,3).

Startup is special: the wizard at (168,197) automatically collects the pearl
at $C733 (slot14) before movement. Its patch runs FIRST: seven repeats of
three cyan bytes, stride3, destination $D832. This makes the words visible,
so that pearl matches the initial $C35F=$1E and is safe. The callback then
sets displayed and remembered request to chalice. Neutral-input startup
was replayed live after selecting L07T at the loader; no pickup state was
poked. The saved mismatching display/request is an initialization state.

Original-code comparison:4096 cases (16 slots,4 remembered symbols,16 color
nibbles,4 random low-bit values). Checked death, branch opcode, both next
symbol stores and all13 color stores. Four isolated live callbacks check
visible/hidden and matching/mismatching cases. Full completion route open.

Every pickup changes SID pitch and the saved $C36F collision-color field, not the separate active $C0A3 value. On odd pickup counts, slot1 clears three three-cell runs and advances each pointer one row, up to twenty times. This path requires $C066=0. Its patch regenerates the pearl. The alternate $C066 path changes actor movement fields instead.

Callback begins with RTS. All sixteen indexed treasure pickups, 1,536 timer-counter/phase cases and 4,096 consecutive terrain updates leave that entry unchanged. Bytes after it resemble a disabled routine, but decoding through $C380 enters patch storage (JSR $0000); removing RTS alone does not establish a working routine. No activation is demonstrated on these tested paths; the fragment’s historical purpose remains unknown.
