docs(phase-33): Drew's decision on outward text — no AI acknowledgement; write the way a developer writes (rewritten from the facts, not de-telled model prose; the dense code-span formatting was the likely giveaway): E1 preset request + E2 Archipelago message rewritten in a developer's voice; rule candidate (j), decision log P33 S89, failure museum row 37, how-to §11 and the checklist reworded

I would like to create a compiler preset on decomp.me.
Preset request for Brave Fencer Musashi (USA). Scratch that matches 100% with these settings: <scratch URL>
- **Preset Name:** `Brave Fencer Musashi (SLUS-00726)`
- **Platform:** `ps1`
- **Compiler ID:** `gcc2.7.2-psx`
- **Compiler Flags:** `-O2 -G0 -mips1 -mcpu=3000 -mgas -msoft-float -fgnu-linker -Wa,--aspsx-version=2.56,--expand-div`

- **Compiler Flags:** -O2 -G0 -mips1 -mcpu=3000 -mgas -msoft-float -fgnu-linker -Wa,--aspsx-version=2.56,--expand-div
- **Libraries (if applicable):** none
Evidence: this scratch matches 100% with exactly these flags: <scratch URL>.
Project: https://github.com/Druthulu/BFM-decomp (218 binaries byte-identical from source with this triple;
docs/decompme-preset.md explains the flags and the local proof through decomp.me's own toolchain).
These are the flags the full matching decomp uses (https://github.com/Druthulu/BFM-decomp), all 218 binaries build
byte identical with them. The -Wa part matters, without --expand-div nothing with a division matches.
```
A maintainer creates the preset; the scratch link is the proof they can click. Check the name's spelling in the issue —
it is immutable once created.

our own probe scratch). That closes the row and completes the greenfield claim's last check.

**Title:** `Matching decompilation of BFM (USA) is public: source and symbols behind your patch sites and RAM addresses`
**Title:** Decomp of BFM (US) is public, might be useful for the AP world
**Body:**
```
Hi. I run a matching decompilation of Brave Fencer Musashi (SLUS-00726):
https://github.com/Druthulu/BFM-decomp. The main executable and all 217 streamed code modules
rebuild byte-for-byte from C, so every RAM address your client touches now has a function or a
variable behind it that you can read.
Hey, I've been working on a matching decompilation of Brave Fencer Musashi (USA) and it's public
now: https://github.com/Druthulu/BFM-decomp. The whole exe and all the streamed modules rebuild
byte for byte from C, so basically every address your client pokes at has a function or a
variable behind it now.
Your world helped us early on (client.py was our richest US RAM source and is credited in the
README), so here is some of it coming back. Offsets below are BizHawk MAIN_RAM offsets like yours.
Your client.py was a big help early on for US RAM addresses (you're in the README credits), so a
few things I found going back through it against the source:
- Day of week: your read at 0x078eba is right. The rollover function (func_8014B084, present in
every location overlay) does day = day + 1 (u16 at 0x078eac, wraps to 1 at 366) and
dow = (dow + 1) % 7 (u8 at 0x078eba).
- Your max-BP patch at 0x14bcf8 sits in a 14-instruction function, func_8014BCEC(a0, a1):
bp_max (u16 at 0x078eb6) += a1, clamped to 0x662. The nop removes the increase.
- The scroll-cursor site 0x13f430 is inside func_8013F350; the old town-ID site 0x15a7e4 was
inside func_8015A3C8; your Time Sanity hook at 0x146280 rewrites a jump inside func_80146128.
All of these are shared engine bodies, byte-identical in every location overlay, so one C
definition in src/shared/engine_core.h covers every map. The entrance byte at 0x18e096 is
per-map code (seven maps, seven different functions).
- One small thing in the version check: the EXE's copy of the ID string is "BASLUS-00726MUSASHI"
starting at 0x072dfc, so the fallback read at 0x072e02 starts at the string's fifth character
and can never match on the US disc. Harmless, since the kernel-area check hits first.
- day of week at 0x078eba is correct. The rollover function bumps the day counter (u16 at
0x078eac, wraps back to 1 at 366) and does dow = (dow + 1) % 7.
- the max BP patch at 0x14bcf8 is in a tiny 14 instruction function that does
bp_max (u16 at 0x078eb6) += arg and clamps at 0x662. Nopping the addu just kills the increase,
so that all checks out.
- the scroll cursor site (0x13f430), the old town id check (0x15a7e4) and your time sanity hook
(0x146280) are all in shared engine code that's identical in every location overlay, so one C
file covers all of them. The entrance byte at 0x18e096 is different per map though.
- minor: the exe's copy of the id string is actually "BASLUS-00726MUSASHI" starting at 0x072dfc,
so the fallback read at 0x072e02 starts 4 bytes into it and won't ever match on US. Doesn't
matter since the 0xba94 check hits first, just thought you'd want to know.
If it helps, I can resolve any address in your client to its function or struct field, and we
would like to name our symbols after your findings where you found them first. Two questions:
is there US RAM research beyond client.py you would be willing to share, and are you fine with
us continuing to cite client.py addresses in our memory map with attribution (your repo has no
license file, so I wanted to ask)?
If you've got US RAM notes beyond what's in client.py I'd be glad to fold them in with credit, and
if you want any address resolved to its function just ask. Also wanted to check you're ok with us
citing client.py addresses in our memory map (the repo has no license so figured I'd ask).
Everything is under docs/memory-map.md and src/ in the repo. Thanks for building the world.
Function names are still func_XXXXXXXX style for now, naming is the next big job.

**Short form** (Archipelago Discord, the game's channel, if preferred): "BFM (USA) now has a complete matching
decompilation: https://github.com/Druthulu/BFM-decomp. Your dow read at 0x078eba is confirmed by the source
(func_8014B084: dow = (dow+1) % 7), your max-BP patch site is func_8014BCEC (bp_max at 0x078eb6 += a1, clamp 0x662), and
every hook site has a named function now. Happy to resolve any address; details in an issue on your repo."

(dense backtick-bracketing of every term, exhaustive bullets, evidence scaffolding, length) instead of rewriting like a person would.
Applied: the E1 preset request and the E2 Archipelago message REWRITTEN in a developer's voice (short, no code spans, casual
register; the decomp.me template's own bullets kept); the bundle file replaced; rule candidate (j), the decision log P33 S89, the
