DeSmuME Wii SVN changelog:
r177
Added USB2 support.
r178
Fix cursor data, was overrunning it's mem. Should have been 16bit for GX_TF_RGB5A3
r179
Lower Rom Cache, form my testing it seems much faster to have a smaller cache. I think the overhead of big file reads is slowing down rom loading.
* If you notice any games loading slower let me know. From my tests several roms load a lot quicker.
r180
*fix Endian issue in write_auxspicnt that was causeing White screen for some games. Remember there is still a white screen due to a save problem so give the game a minute to verify this fix works for you.
