When I try to load certain levels from Rayman 2 on PS1 I get the following message: "PointerException: Not a valid pointer at <level_name>". The strange thing is that the error only appears for some levels while other levels load normally. On 57 maps, there are 22 maps that fail to load. I've tried with several versions of the game, but each time it's always the same levels that have this problem. Here is a complete example of an error: PointerException: Not a valid pointer at learn_10.dat|0x80197268[0x000AC968]: 983040
