Back to the topic, I decided to use Stacey's trick in the Dolphin emulator for the crash of Rise and Shrine and it really avoids the game freezing in the start (Pressing the A button a lot before the loading finishing and in the moment of the start of the level) so I got able to pass through. I believe I can complete the game for the first time now, its just a matter of time. And if FRAPS holds the game well, I might do a walkthrough for Rayman Arena.
It disappoints me how the battle mode got ridiculously easier in terms of gameplay, although I find more clever the tongue of fire working like Mario Kart: Double Dash's Mario & Luigi special attack.
