Partitions are Wii-exclusive, and don't happen at the DVDInterface level in
IOS. This isn't quite the cleanest fix, but it gets rid of the assumption that
a partition is open on starting the game at least.
The various ioctls sometimes have different arguments than the DI command
registers, though they generally overlap. There are also a bunch of ioctls
that don't even normally go into DVDInterface, just returning various data.
Some of the implemented ioctls are new to Dolphin.
Previously, only Mii data was written. Additionally, the file containing mii data was shared for all Wiimotes, which made it a lot less useful.
Additionally, the file was read/written on each Wiimote read, even though the whole EEPROM was kept in memory. This was bad for performance and not particularly necessary (it did enforce that the data was properly shared between all Wiimotes, but that's not something I want).
Bug 1: subcommand 1 of 0xE1 does not actually reset the current position; it just stops playback. 0xE2 returns the same value it would have before stopping playback (other than reporting that the stream is stopped).
Bug 2: subcommand 3 of 0xE2 was incorrectly dividing the length by 4; while this makes sense for positions (which are multiplied by 4 earlier to get a byte offset), it is not correct for lengths.
Previously, IR calibration data with an invalid checksum was used, because the calibration produced a strange offset. I've replaced it with calibration data that encodes the same values as the data Nintendo falls back to when the checksum is bad.
It already is disabled for other backends, but this didn't happen with the software renderer. Attempting to change it while running causes the change to visually happen (including switching to the normal render settings UI instead of the barren one for the software renderer), but doesn't actually change the backend itself (it'll still use the software renderer at the next launch).
WindowModal allows alt+tabing to the render window, but prohibits interaction
with parent windows (controller settings window and the main dolphin window).
