- Dependencies: `pip install construct PyCryptodome`
|
||||
|
||||
## Patchers
|
||||
- `patchers/b2spatch.mjs`: Convert from BemaniPatcher to Spice2x JSON
|
||||
- Requires `cheerio`: `npm i cheerio`
|
||||
- `patchers/b2spatch.ts`: Convert from BemaniPatcher to Spice2x JSON
|
||||
- Use Deno: `deno run -WNE b2spatch.ts ...`
|
||||
- You will need to rename the resulting JSON manually so that they match the
|
||||
`{gameCode}-{timestamp}_{entrypoint}` format expected by Spice2x.
|
||||
- `patchers/b2mpatch.ts`: Convert from BemaniPatcher to [mempatch-hook](https://github.com/djhackersdev/bemanitools/blob/master/doc/tools/mempatch-hook.md)
|
||||
- Use Deno: `deno run -A b2mpatch.ts ...`
|
||||
- You need to setup a folder of executables or DLLs you want to patch. They
|
||||
can be named the patcher's description, or the patcher's filename.
|
||||
|
||||
## Arcaea
|
||||
- `acaca/arcpack.py`: Script to extract Arcaea Nintendo Switch `arc.pack` files
