I posted this on the EZFlash forum too and some one suggested I try asking here. I've done as much research as I could and tried everything to get the rumble working on Metroid Pinball but the rumble still doesn't work. I have a AK2 and 3in1+. I've done all of the following: Installed the latest AKAIO 1.4.1 Proper Formatted my 8g SDHC card with Panasonic SDHC formatter 2.0 Gone to the AKAIO menus for the games and turned the rumbles on and off Read the wikis for the EZ Flash and AK2 setups Tried patching with 3in1 rumble patch even though I probably didn't have to Tried 2 versions of the game (EU) and (US), still rumble is greyed out on both games Does anyone know why the rumble choice is greyed out in the options menu? I also can't seem to get the rumble working on Super Princess Peach either. The rumble rumbles when I am loading the game and when I change the rom/AKAIO settings, but after that, there is no rumble during game play. What am I doing wrong or what have I NOT done? Any help on this is most appreciated. I searched and searched the forums for answers to this problem but it seems like it may be unresolved. If anyone can share a step-by-step procedure on how they got their rumble to work for any of the rumble games (I would love for Super Princess Peach to work too), I would greatly appreciate that too. Thanks!
