What

20 functions in C, all matching every place:

• 2 in USA v1.01;
• 18 PAL-only functions (func_PAL_…), 24,728 distinct bytes over 52 places.

USA v1.01

• func_L15_004307E0 (Gorn cutscene controller, 848 bytes). func_0029B3E0 returns int, as its matched definition in src/game/0029AE78-save-g8.c does. With the value-returning call, local-alloc gives retail's registers after it; a void declaration swaps $v0/$v1.
• func_L23_0041A3B8 (Damosel effect trigger, 652 bytes).
  • Its kind 0xF arm groups its real effect (two calls and a store) in a nonempty one-pass statement. That is the RAC1 source method recorded in docs/COMPILER-NOTES.md (Match five HUD and level initialization functions #417).
  • The group's loop notes keep the la of D_L23_001B3850 ahead of the two frame-address arguments.
  • func_L00_0035F5A0 returns int, as its matched definition does.

Both near-miss notes and their functional copies are removed.

PAL

Each unit is the C of a matched v1.01 function, changed only where PAL's bytes differ. Its header names the v1.01 twin and lists every change.

PAL function	v1.01 C	Bytes	Places	What changes
func_PAL_L14_00427108, L15_004241F8, L17_0041D4E8, L18_0043BDE8, L20_0043E868, L22_00414080, L23_0041A950	func_L00_0040EAA0	1540 each	1 each	only the callees' PAL names
func_PAL_L00_002C3250	func_L00_002C30B0	1928	16	50 Hz timer steps (1/600 → 1/500 …)
func_PAL_L22_002C8740	func_L22_002C8610	2012	2	the same
func_PAL_L18_002DF168	func_L18_002DEFF8	2016	2	the same
func_PAL_L20_002D6678	func_L20_002D6488	2044	1	the same
func_PAL_L01_003BD328	func_L01_003B9798	1944	2	lift steps scaled by 60/50 (0.1 → 0.12) and (60/50)² (0.00167 → 0.0024)
func_PAL_L02_003D06F0	func_L02_003CC7B0	1304	2	the 300-frame timer becomes 250
func_PAL_L05_004212A8, 004225D0, 0042BD38, 0042C2E8, 0042C880	func_L05_003CD598	540 each	4 each	see below

The five func_PAL_L05_… glow rings each change in three ways:

• the fade count goes from 255 to 212 steps (≈ 255 × 50/60);
• its reciprocal goes from 0.0039215689f to 0.004716981f;
• each copy has its own pair of colours.

The unit flags are the v1.01 file's.

Not included

The 22 menu accessors func_PAL_L00_0030F* carry the same way, from func_L00_0030D240. They match 23 of 27 places each. The other 4 fail because the PAL catalogue's places for these entries are shifted by one in levels 05, 10, 15 and 25, which is a catalogue repair (#421). They stay INCLUDE_ASM.

Checks

On this branch, rebased on 5e3add6f:

• tools/build.py all --strict: 28/28 USA v1.01 programs OK;
• tools/build.py all --strict --version pal: 28/28 PAL programs OK;
• python -m unittest discover -s tests: 383 tests OK;
• tests/check_repository.py and tools/progress.py --check pass.

USA v2.00 was not built, because I don't have its dump. func_L23_0041A3B8 exists there with the same fingerprint; func_L15_004307E0 and the PAL functions do not.
