Action Replay confirmed WORKING with 3.0U (latest ver with internet fix). So i read some pages and i found that the general consensus is that action replay no longer works. I'm not sure if its been discussed as of yet, but i found a way to make the AR 1.14b (version i have) work, along with another action replay MAX my friend had. What you need to do is load gcos multigame and wait till it asks u to insert a dvd to load. Eject the gcos multigame disk and insert the the AR disk. The AR splash screen shows and then you can enable some codes. I recently got Naruto 4, so i went online and searched for some codes to manually type in. I went to the japanese section and type them in. Then i saved them and it told me to eject the disk. Now this is the important part. When you eject the disk, the wii will automatically reset itself. If you had action replay inside a GCOS multigame image, the wii will reset to the GCOS menu asking you to select a game. This will keep happening over and over, so maybe that is why people said that AR no longer works even with gcos. However, if you only used a GCOS multigame disk as a loader for an AR disk, then when the wii resets itself, it will reset back to the original AR menu and this time, it will work when you eject the disk. Everything will be normal and you can switch the AR disk to the game disk (i.e. naruto 4). I have unlocked all the chars in naruto 4 and all the stuff in gnc warioware using this method on my wii, so i know it works. The setup i have now for AR is the following- A gcos multigame burned image with AR 1.14b inside. I labeled it AR loader. I use this image to get to the AR menu, and RIGHT AFTER i exchange that disk with another one i called AR (real disk) - which is simply the AR burned on a disk without GCOS . THen when action replay asks to switch disks, the wii will reset, and this time will load the AR from the new disk, and that will work. so gcos multigame AR does not work by itself. And regular AR disk is blocked from being read by the 3.0 firmware. However, combining the gcos multigame disk as a loader for the regular AR disk will work. You just gotta swap the disks when you get to the AR menu and then activate some codes and press start until it says "eject disk". WHen you press eject disk, the wii will reset itself and load the regular AR disk without problems. THen you will be able to enable codes and eject that disk without it resetting again, and now you can swap that disk with a game disk. Hope this helps anyone, and i havent tried any of the freeloader features built into AR since my wii is partially region free. this method might work with some other stuff as well.
