The WSR file format is used for storing music routines from WonderSwan software, not unlike the NSF format. It was initally defined and implemented by the in_wsr Winamp plugin.
Its format is based on the ROM header format, with files expected to be a multiple of 64 KiB in size. However, the footer at the end of the file is 32 bytes long, not 16:
| Offset | Length | Contents |
|---|---|---|
| $00 | 4 | Magic string: WSRF |
| $04 | 1 | Version number; currently $00 |
| $05 | 1 | Starting song number |
| $06 | 10 | Reserved |
| $10 | 16 | ROM header |
The JMP instruction in the ROM header points to the song playback routine; AX is set to the song number.
