- 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.
Moves NES PowerPad Test Card (U) from _wip/ to NES PowerPad Test Card (U)/ with full ROM build:
- Adds header.s, chr.s, linker.cfg (HEADER+PRG+CHR segments)
- Updates Makefile to build and verify reconstructed.nes vs rom.nes
- Adds rom.nes copy + copilot/rom.nes symlink per repo convention
- Verified byte-identical build
Pass 1 complete: full code/data classification (~7.2% code / ~92.8% data)
Pass 2 complete: routine headers for all ~50 labels, semantic naming for key
routines (Reset, NmiHandler, VramWrite, ReadPad, ProcessPads, etc.),
zero-page aliases in locals.inc (Zp00-Zp15)
Pass 3 complete: data tables named (PaletteData at ,
PadBitTableLives at )
Root OVERVIEW.md updated:
- Removes NES PowerPad Test Card from _wip skeleton table (21 → 20 skeletons)
- Adds NES PowerPad Test Card as #15 in numbered inventory (BYTE-IDENTICAL, Pass 2/3)
- Updates summary count from 14 to 15 projects
