- Decoded the VramWrite ($E1CC) stream format: <addr hi> <addr lo> <count> <bytes>, $00 terminator - Named all 9 payload streams ($E4CC-$E7C2, no gaps/overlaps) plus VramWriteSourcePointerTable at $F000 - Split PadBitTableLives into Player1TileTable ($E4B4) and Player2TileTable ($E4C0), 12 entries each (Y=0..11) - Decoded CHR font (digits $30-$39, letters $3A-$52, space $5F; 'W' missing from the A-Z run) and recovered on-screen text including 'PRESS A TO TEST SIDE-A' / 'SIDE-B' - Documented that the 16 KiB PRG is two byte-identical 8 KiB halves; $C000 copy is dead - Documented 7 unreached subroutines inside the live code region (kept as .byte per Pass-1 policy) - Fixed a stray duplicate sentence and stale _wip paths in root OVERVIEW.md Byte-identical ROM verified.

# Zero page $14/$15 is the 16-bit block counter for the compressed-VRAM transfer path and

# the collision-bit accumulator for the overlap test. locals.inc names both roles; this

# set-ups, so the same byte is not mislabelled at every site.
