# RAM-dump corpus — Phase 3 live PCSX-Redux captures (2026-06-14)
|
||
|
||
Full 2 MB PS1 RAM images pulled from the Windows-native PCSX-Redux web API
|
||
(`GET http://172.17.208.1:8081/api/v1/cpu/ram/raw`) while Drew played a fresh SLUS-00726 run.
|
||
Each is a labeled game-state snapshot — a reusable corpus for offline RE in later phases
|
||
(overlay map, player-state, save-format) **without re-playing the game**.
|
||
|
||
- **The `.bin` files are gitignored** (ROM-derived 2 MB game memory; 57 MB total). This INDEX is committed.
|
||
- They are **NOT cheaply regenerable** (each needs replay to the exact state) — back up `dumps/` off-machine
|
||
if you want them safe against disk loss (same as `disks/`). While private, they *could* be pushed (H1
|
||
relaxed), but local + this index matches the `disks/`/`extracted/` hygiene.
|
||
- Resident blob always @0x800CEDF8 (`MAIN.CD/FILE_010/1.1`); location overlay slot @0x80128158.
|
||
- Verified addresses derived from these live in `docs/memory-map.md` (§3.4, §4.3, Q#1/#3-#6/#9/#12).
