…ther retail regions Four plain-Python tools (standard library only) that produce everything a non-PAL project needs from that region's own executables: - port_map.py ports projects/mkwii/MAP.txt through the community PAL->E/J/K chunk tables (vendored from mkw-sp's port.py, MIT; recorded in THIRD-PARTY-NOTICES.md) and keeps only entries the target main.dol/StaticR.rel vouch for: call and relocation targets, exception-table records, function-pointer tables, or at least a terminator followed by a decodable first instruction. Every dropped or unverified entry is listed in the MAP_REPORT.md it writes. Output is deterministic. - port_data_addresses.py re-derives the NTSC-J and NTSC-K addresses of every data global the runtime names from the hand-verified NTSC-U evidence table, by decoding the instruction at each ported reference site and checking it against the independent chunk-table port. A row it cannot establish is written out as UNRESOLVED rather than guessed. - gen_region_headers.py scans the runtime for the PAL identities it names (MKW_GADDR / MKW_GUEST_FUNC) and writes runtime/include/region/<region>.h; an identity that cannot be resolved is an error. - disasm.py disassembles a range of a region's DOL/REL with llvm-mc and annotates the address each r13/r2 access forms, for adding evidence rows. README.md next to them documents the mechanism, the verdicts, and how to regenerate. .gitignore keeps ignoring local scratch under tools/ but tracks tools/region/.
projects/mkwii-ntsc-u, -j and -k mirror projects/mkwii with the facts that differ per region: game ID, the small-data bases __init_registers installs, the StaticR.rel load address, the clean-input digests, and the region header the runtime resolves its guest addresses through (runtime.guest_address_table). Output goes to generated/ like the PAL project, so the existing build pipeline applies unchanged. MAP.txt, MAP_REPORT.md and region_port.json are tools/region/port_map.py's output for each region (29,409 / 29,429 / 29,439 entries; nothing is emitted that the region's own binaries did not confirm). data_addresses.txt lists every data global the runtime names. The NTSC-U table is the hand-built source of truth: each row records the NTSC-U address and the instruction(s) that reference it. The NTSC-J and NTSC-K tables are generated from it by port_data_addresses.py (106 of 129 rows confirmed by disassembly, the rest by the chunk table alone, none unresolved) and are not edited by hand.
…gion The runtime's HLE names addresses inside the game executable: the functions it replaces, the SDK globals it reads and writes. Those differ per region, and writing them as offsets from r13/r2 does not help: the small-data blocks are not laid out the same way in every region. RMCK01 keeps much of .sbss 0x20 lower than PAL, so the PAL offsets the OS stubs used landed on unrelated globals there: __OSInitSTM wrote its fake handles over OSDisableScheduler's nesting count (the game hung in OS::Init), the ISFS bring-up wrote the filesystem state over unrelated globals (the save-data check failed), the alarm stubs walked a string table instead of OSAlarmQueue (a fault every frame), and OSSetPowerCallback kept its state 0x20 away from where the game reads it. Every guest address is now spelled as its PAL address and used as an identity: MKW_GADDR(803868A0) expands to MKW_G_803868A0, which the region header defines as that object's address in the executable being built; MKW_GUEST_FUNC does the same for a translated function's symbol (runtime/include/region/guest_region.h). The four headers are generated by tools/region/gen_region_headers.py from the projects' tables. PAL's maps every identity to itself, so the PAL build compiles to exactly the constants it did before. The region facts the HLE reports to the game (game code, TV format, SC area / game region / product code, initial MEM1 arena) come from the same header as MKW_REGION_* instead of PAL literals. The header in use is named by generated/RuntimeConfig.h (MKW_GUEST_REGION_HEADER, written by the translator from the project's runtime.guest_address_table), so the runtime always binds to the executable generated/ was translated from; a RuntimeConfig.h without that line can only be PAL and gets rmcp01.h. Two things this exposed beyond Korea: the EGG fog constants in .sdata2 sit 8 bytes further from r2 in NTSC-U than in the other regions, so the hardcoded PAL offset read 176.0 / 176.0 / 1.0 there instead of 0.0 / 0.99 / 0.5; and the three AX DSPTaskInfo halfwords were read through hardcoded r13 offsets. All are named by identity now; no r13/r2 address arithmetic is left in the HLE. kDefaultEntryAddress stays a literal: __start is 0x800060A4 in every region, and Launcher/Test-PinnedFacts.ps1 reads that line as one.
…e project's region table The translator scans runtime/src for native registrations and reads the addresses out of the source text. With the runtime spelling every guest address as a PAL identity, that scan has to see the same addresses the compiler will produce. A project now names its region header in runtime.guest_address_table. Before any source scan, GuestAddressTable loads the header's MKW_G_ defines and rewrites the address-carrying spellings (PPC_NATIVE_OVERRIDE, GX_FATAL_STUB, MKW_GADDR, MKW_GUEST_FUNC) into the region's literals; a spelling it does not recognise fails loudly rather than letting a PAL address through as this region's. The same path is written into RuntimeConfig.h as MKW_GUEST_REGION_HEADER, which is how the runtime picks its region header, so the translation and the runtime build cannot disagree. projects/mkwii names rmcp01.h, the identity table, so PAL goes through the same code path and resolves to the addresses it always had. Projects without the field (generic DOLs) are untouched. Tests cover loading, resolution, every rewritten spelling, the loud failure, and the RuntimeConfig.h line.
Setup still accepts only RMCP01; the FAQ says so and points at the region projects and tools/region/README.md for the rest.
- gen_region_headers.py: propagate main()'s exit code, so an unresolved identity fails the process and not just the log. - port_data_addresses.py: classify spans by their executable flag (DOL text section index, REL section-table bit 0) instead of an address threshold, so masked matching indexes REL text and can never index DOL data as instructions. Regenerating the J/K tables changes no row: no committed address came from the matcher. - port_map.py: the SDA expectation and the bss note follow --region instead of hardcoding NTSC-U's values; the J/K reports now read "matches expectation" instead of flagging their own correct bases. - riivolution.cpp: the fallback comment describes the region game code, not RMCP.
markdownlint flags bare fences; the two report emitters now open with ```text. The other two nitpicks are left alone on purpose: the shared-decode-module refactor is a follow-up, and the music_attenuation D-Bus comments are about code this PR does not add.

The translator/runtime support looks like a good foundation, but the end-user integration is still incomplete: setup rejects non-PAL discs, fresh NAND creation still hardcodes European settings, and the documentation says mismatched extracted assets can cause a texture-loading panic? wdym with that these things should be resolved |
Will work on these next and see what the author meant by the texture loading panic |
…cs in setup, and validate dvd region
The extracted disc files (UI layouts, localized fonts, etc.) differ by region. If you ran, say, an NTSC-U build with extracted PAL assets, Nintendo's nw4r::g3d engine would panic when trying to bind missing or misaligned textures, making it look like a recompiler crash. To prevent that confusion, I added an early check in dvd.cpp that reads sys/boot.bin on startup and pops up a clear "DVD region mismatch" error if the assets don't match the executable. |

Hey @patchzyy, I've addressed all the review feedback in the latest commits: Corrected the area table in sc.cpp and gen_region_headers.py to match the SDK table from the PAL DOL, and return 0xFFFFFFFF on unknown strings. All unit tests and pinned-fact checks are good. Let me know what you think or how you'd like to proceed! |

Supersedes #104. Bringing this over since the original PR went inactive, keeping all of @rooklz's original commits to preserve his credit.
Looking over the code and his last comment, his original design is actually completely fine to merge as-is. The macro identity mapping resolves everything at compile time with zero runtime overhead, and having MAP.txt in each project folder matches how the PAL project already works so users don't need extra tools to build other regions.
I rebased the branch onto latest main and fixed a conflict in sc.cpp. Upstream commit d1d8061 was reading raw PAL memory addresses to look up NAND console settings, which broke on non-PAL discs. I updated that to map the setting strings directly and fall back to the region's constants when not present.
I ran all the tests and verified everything:
Note: NTSC-U is 100% verified against disassembly; NTSC-J and NTSC-K use a best-effort section-relative fallback for two symbols (802574A0 and 8088FDB8), which will be refined with relocation tracing in a follow-up issue.
