Unravel your GFA archives.

Upload one archive, supported game file, or folder. Replit keeps the original folder paths and checks code → content → meta, extracting nested files in place. GFA and SARC/Yaz0 archives are unpacked, RPX/RPL becomes ELF and C++ output, BSON/MSBT become JSON, BFSEQ event data and MSBP project tables are exported, BFFNT sheets and metadata are extracted, GTX/BFLIM become PNG, and BFSAR/BARS/BFGRP audio libraries are expanded before supported audio becomes WAV or MP3. The result is one ZIP with the same directory structure.

Files are uploaded to Replit and processed in temporary storage, then deleted after download or 30 minutes. Upload allowance: 16 GiB upload and 18 GiB temporary data. Image/audio conversions replace their source; BFLYT and BFLAN keep their originals and gain raw-section exports; BFSAR resolves named audio assets and recursively opens nested BFWAR wave archives before converting supported streams to WAV. MAPBIN is exported as editable structured JSON while its original stays in place. Unsupported or failed files stay unchanged and are listed in the report. BNTX is not decoded here; native audio loop metadata may not survive conversion. This does not convert a game executable into a playable web game.

Upload an RPX or RPL file. Replit decompresses it to ELF, translates supported PowerPC blocks to C++ files, and returns one ZIP. This converter is also included in “Extract everything.”

Generated C++ is translated source, not a playable game; unsupported blocks are reported in the ZIP.

Choose a .gfa archive. WoollyTools will unpack its files and bundle them into a ZIP download.

Select a folder of extracted game files and rebuild it as a Good-Feel archive.

Extract indexed BFRES subfiles and convert FTEX textures to GTX/PNG. FMDL model payloads are exported raw; OBJ/glTF geometry conversion is not available yet.

Model data is exported raw; full 3D mesh reconstruction is not included.

Decode supported Wii U GTX texture formats and download the images as PNG files.

Uses the supplied GTX Extractor in your browser. First use downloads the Python runtime; your texture stays on your device.

Decode supported Wii U GX2 BFLIM formats to PNG in your browser. The file stays on your device and the original texture metadata is included in the ZIP.

Uses the included GTX Extractor GX2 decoder. Unsupported BFLIM encodings are reported; they are not converted to placeholder images.

Export the Wii U Cafe layout header and each top-level section as a raw file. JSON also extracts text-pane strings and summarizes pane names, visibility, transforms, and dimensions; this does not render or edit the layout.

Export the Wii U Cafe animation header and each top-level section as a raw file. JSON includes animation names, frame ranges, groups, textures, pane/tag summaries, and supported track keyframes. This does not preview or edit animations.

Open and edit the complete level tree as structured JSON, then rebuild a MAPBIN file in your browser. All ten node types and versioned fields are supported; the source file stays on your device.

Extract named AMTA metadata and embedded Wii U audio assets. Supported waves and streams continue through to WAV; unknown payloads are kept as raw data and reported.

Read the BFGRP INFO references and FILE payloads, then recursively convert supported embedded audio. The original archive and unrecognized payloads are retained.

Extract SARC files directly and decode Yaz0-compressed SZS/SARC archives. Nested supported game files continue through the recursive extractor.

Extract the bounded DATA event stream and any LABL section. This is sequence code, not rendered audio; producing WAV requires its sound bank and a compatible synthesizer.

Export project sections, CTI1 strings, and SLB1 label groups as JSON and raw section files. MSBP is project metadata; dialogue text is stored in MSBT.

In one run, read the INFO references and FILE pool, extract named audio assets, open nested BFWAR wave archives, and convert supported BFWAV tracks to WAV. The original archive stays in the ZIP.

BFSAR uploads are processed in temporary Replit storage. BFWAV and supported stream files are converted to WAV in the same run. Sequence/label files such as .bfseq, .seq, and .labl are data, not standalone audio; rendering them requires matching sound banks and wave samples. Unsupported audio containers are kept and listed in the report.

Unpack the wave table and embedded BFWAV/BCWAV files. Supported Wii U waves are converted to WAV in the same run; the archive and a wave manifest are included in the output ZIP.

Decode a Good-Feel BSON file in your browser with the Rust/WASM engine, then download the JSON result. The file stays on your device.

Read labeled MSBT messages and export text, message IDs, sections, and raw bytes for tagged entries as JSON. Also included in “Extract everything.” Limit: 128 MiB.

Export font metrics and character maps as JSON, keep each original texture sheet, and decode supported Wii U font-sheet formats to PNG. Also included in “Extract everything.”

Batch-convert supported Nintendo game audio and common audio files to WAV, FLAC, MP3, or OGG. BFWAV is decoded with vgmstream; conversion runs on Replit and returns a ZIP.

Uploads are temporary (512 MiB per file, 2 GiB total). Originals are not included in this ZIP. Loop markers and format-specific metadata may not carry over.

Decode a Wii U Cafe BFWAV sound file with vgmstream and download the PCM audio as WAV. Also included in “Extract everything.”
