I received my FlatMii, installed it (tight fit!) and here's my results:
Most of my games play well. There is some lag in the movies on some games. This is directly connected to my USB2.
MY FLATMII IS COMPLETELY INCOMPATIBILE WITH USB EXTENSION CORDS!!!. Dear GOD almighty, this drove me insane. If I have a USB extension cord or have the FlatMii plugged into a (powered or unpowered) USB hub, it basically fucks my entire USB/Bus system, rendering HD inoperable until I restart the computer. I've confirmed this with 3 different brand USB2 extension cords to no avail.
My orange and red lights are gone after installing the FlatMii. The light either shows green (on) or nothing (completely off). The ISO420 review confirmed this behavior.
Also, these games do not work on my FlatMii (brickblocked only):
BLACK SCREEN
Bleach Versus Crusade [JAP] = black screen
Animal Crossing - City Folk [USA] = black screen
Call of Duty - World At War = black screen
Dragon Ball Z Budokai Tenkaichi 3.iso = black screen
Need For Speed - Undercover [USA] - black screen
Marble Saga Kororinpa [USA] = black screen
MadWorld [PAL]
Weird pseudo-English/Japanese character across screen
Captain Rainbow = weird characters across the top part of the creen. Game works fine, but sound seems a little garbled. I think this is part of the game though to "replicate" speech
The only game incompatible with FlatMii's "autoboot" (handy!) feature is Super Smash Bros.
!!!!!!! QUESTIONS FOR FLATMII OWNERS !!!!!!!!!!!
1) Can you guys test the aforementioned games and confirm/deny that they work? The reviews state all games work
2) Lily already said he/she uses his FlatMii with a USB extension cord so I am baffled. Mine simply doesn't work with a USB extension cord.
3) Can you tell me what games do not work with Autoboot w/ the FlatMii?
4) Do you guys experience the disappearing red/orange light as stated above?
I have Wii 3.2U + Starfall + TheHomeBrew Channel (but not loading any of them).
