现在swiss已经支持换盘了，不过要两张SD卡，游戏iso必须在卡上同一顺序才可以。

SD swapping seems to work on the Wiikey Fusion for all multidisc games. When asked to switch discs simply swap the SD card to a SD card with the next disc .iso on it and flip/press your lid/open closed switch. There is however one other catch.
When adding games to SD card it seems that the Wiikey uses whatever "slot" the game is loaded to to identify what image to mount if the SD card is removed and reinserted during gameplay. So if on one card you have 5 games and on another card you have 3 games and the multidisc game you are playing ends up in a different slot than it is on the first SD card. The trick will not work.
Example:

DOES NOT WORK	SD CARD 1	SD CARD 2
	1. GAME A	1. GAME C (disc2)
	2. GAME B	2. GAME D
	3. GAME C (disc1)

WORKS	SD CARD 1	SD CARD 2
	1. GAME A	1. GAME D
	2. GAME B	2. GAME E
	3. GAME C (disc1)	3. GAME C (disc2)
		4. GAME F

The game needs to be in the same "slot", to work.

哪里看来的消息？SWISS在GOOGLE的源代码还停留在243，根本就不支持换盘。如果说的是Wkf的官方固件的话，一直都支持。

确实，是我搞错了，swiss目前还不行，官方固件才可以。
