Grandia 2 lockup problems

[MVD]

Hello,

I'm new to this board, but I hope you guys can help me out.

I've got a backup of grandia 2, and it works fine for most of the time. However, at a certain point, quite late in the game, Ryudo becomes posessed by Valmar and grabs his arm (They are standing on a bridge in a village). At this point, I cannot seem to continue the game. It doesn't really freeze, as you can still hear the bird flapping his wings and you can see a guy walking. But it appears as if the game is in some infinite loop or something. Does anyone know how I can continue the game from this point onwards?

I suppose only those who finished the game on a backup can be of help here, as it happens quite late in the game.

Any Ideas? Thx,

MVD
