it seems like these two bytes are different for every Mii in Wii Sports Resort (including both Miis new to Wii Sports Resort and Miis returning from Wii Sports). the only difference between the two file formats is that there are an additional two bytes at the very end of the file. that's all good and dandy, but what's interesting is that they moved from. rcd file that they use follow the exact same format that can be seen on the bottom of WiiBrew's Mii_Data page or using RiiConnect24's Mii Editor (can't link to them since i'm a new member, whoops). i've recently taken an interest in modifying games like Wii Sports in their CPU Mii data. The program works only from the command line if you click the link, you will also see a description of how to use it.Heya. To download the offline version of the program, click here: Offline Roland to MIDI Converter.

I have written a program (called roland2midi) that will try to convert the Roland files to a ".mid" file. The rsd (Roland Song Data?) file contains the actual song data, and I think I've managed to decode this file completely. I have not decoded this file completely, but I don't think most of the data in this file is relevant when converting to MIDI. The rsc (Roland Song Context?) file contains the name of the song and other general data about the song. Each song is stored in two files, one with extension ".rsc" and one with extension ".rsd".

Roland uses their own proprietary format to store songs.

I am a programmer by profession, and one of my hobbies is to reverse engineer file formats, so I looked at the Roland files to see if I could convert them myself. I searched the net for other ways to convert the files to the MIDI format, but all I could find was a trial version of a program called "Roland V-MT Visual Music Tutor", and it would not let you save your files! The JW-50 actually lets you save your songs in MIDI format, but I have had problems with that function - I have at least one song that crashes the keyboard if I try to save it in MIDI format. I have a Roland JW-50 Music Workstation, and I've been worried about what would happen to all my music (stored on old 3.5" disks) when the keyboard (or the built-in floppy drive) dies one day.
