|

| 19 | # to just follow their lead. The most interesting bit is probably the
|
|---|
| 20 | # 0x20000 option, which ensures the correct byte order for the
|
|---|
| 21 | # extracted audio. This allows the resulting BIN/CUE files to be run
|
|---|
| 22 | # in the Mednafen emulator, which is useful for testing.
