# Pinball (JU) — Pass 2 Complete
|
||
|
||
ROM: `_wip/Pinball (JU)/Pinball (JU).nes` (24,592 bytes, iNES). Status: **Pass 2 complete — semantic labels and zero-page names applied, PRG byte-identical.** `copilot/prg.s` now contains a classified disassembly with 4,734 instructions (59.5% code), 196 semantic labels, and 150 zero-page semantic aliases. The build is **BYTE-IDENTICAL** at the PRG level.
|
||
|
||
|
||
## ROM Facts
|
||
|
||
| Property | Value |
|
||
|----------|-------|
|
||
| Mapper | 0 (NROM) — from the iNES header |
|
||
| PRG | 16 KB (header claims map at CPU $C000–$FFFF) |
|
||
| CHR | 8 KB |
|
||
| Mirroring | Horizontal |
|
||
| Battery-backed flag | clear |
|
||
| ROM SHA-256 | `451a201c067bbabad8d762c3fdc2a83cb0b93f26ed0c350cf23bbf486f7addb6` |
|
||
| PRG SHA-256 | `1d79f41ef62d5045db2c45c9c75766d54c0a84e167d8067bbb6fb90227ac5619` |
|
||
|
||
## Interrupt Vectors (taken from PRG $3FFA–$3FFF)
|
||
|
||
| Vector | Target | Note |
|
||
|--------|--------|------|
|
||
| NMI | `$C1ED` | per-frame heartbeat |
|
||
| RESET | `$C000` | cold start at $C000 — the usual pattern in this repo |
|
||
| IRQ | `$C1ED` | target $C1ED — verify during Pass 1 |
|
||
|
||
## `copilot/` Contents
|
||
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `Pinball (JU).nes` | original ROM image (reference) |
|
||
| `prg.bin` / `header.bin` / `chr.bin` | split image, produced by `_tools/splitnes.py` |
|
||
| `prg.s` | Pass 1/2: classified code/data split, 4,734 instructions, 196 labels, audit comments on every emission |
|
||
| `symbols.inc` | shared NES hardware constants (PPU/APU/controller, from the skeleton) |
|
||
| `locals.inc` | 150 zero-page semantic aliases (filled in by Pass 2) |
|
||
| `linker.cfg` | PRG at $C000, 16 KB, `fill = yes` |
|
||
| `Makefile` | links `reconstructed_prg.bin` and `cmp`s it against `prg.bin` |
|
||
| `reconstructed_prg.bin` | build output from the last verified build |
|
||
|
||
Header/CHR are reproduced verbatim from `header.bin`/`chr.bin` (not linked): `make` verifies **PRG bytes only** at this stage. When this project is promoted to a full disassembly, `header.s` / `chr.s` (as e.g. `Burger Time (U)`) and a full-ROM `make` target get added.
|
||
|
||
## Build
|
||
|
||
```bash
|
||
cd "_wip/Pinball (JU)/copilot"
|
||
make # → cmp reconstructed_prg.bin prg.bin → "BYTE-IDENTICAL"
|
||
```
|
||
|
||
## Next Steps (per `PROMPTS.md`)
|
||
|
||
1. **Pass 3** — name data tables/structures; release provisional flags.
|
||
2. **Promotion** — move to a top-level `<name>/copilot/` folder, add full-ROM build (header.s + chr.s + vectors), and write the power-on flow `OVERVIEW.md` in the established style; then it joins the root index's numbered inventory.

|
||
## Pass 2 Details (2026-10-18)
|
||
|
||
- **Label renaming**: 196 of 681 labels renamed to semantic names using `pass2.py apply` with a mapping file (`pinball_label_map.tsv` + `pinball_zp_map.tsv`). Key renamed routines:
|
||
- RESET/NMI: `Reset`, `NmiHandler`
|
||
- System init: `InitSystem`, `ClearZeropage`, `InitGameState`
|
||
- Main loop: `MainGameLoop`, `GameModeTitle`, `GameModePlay`, `WaitVBlankFrame`
|
||
- NMI: `NmiHandler`, `NmiFrameEnd`
|
||
- Ball physics: `BallPhysics`, `CheckTilt`, `CheckBallInPocket`
|
||
- Flipper logic: `UpdateFlipper`, `UpdateFlipperSprites`, `UpdateFlipperSound`
|
||
- Ball physics: `BallPhysics`, `UpdateBallPosition`, `UpdateBallVelocity`, `UpdateBallTrajectory`
|
||
- Collision: `CheckCollision`, `CheckFlipperHit`, `CheckBallInPocket`
|
||
- Scoring: `UpdateScore`, `UpdateScoreDisplay`, `DrawScore`, `DrawDigits`
|
||
- Sound: `InitSound`, `PlaySound`, `UpdateMusic`
|
||
- PPU: `WaitVBlank`, `WaitPPUReady`, `WritePPU`, `DrawSprite`
|
||
- Sound engine: `UpdateSoundEngine`, `UpdateSoundChannel` (1-35)
|
||
- **Zero-page semantic aliases**: 150 aliases in `locals.inc` (e.g., `FrameCounter`=$02, `GameState`=$03, `PlayerLives`=$04, `BallX`=$24, `BallY`=$25, `BallVelX`=$26, `BallVelY`=$27, `FlipperLeft`=$28, `FlipperRight`=$29, `SpriteIndex`=$95, etc.)
