Problems with PS2V5-PNP KEY

[Juanillo]

I have purchased two months ago one v5-PNP KEY-non soldering modchip. I don't have problems playing backups with some games (Winning Eleven 6, Spiderman-the movie, VF4, ICO...) but I have problems with other games: Redcard Soccer, Airblade, Maximo, Vampire Knight... Some of my friends have a Neo 2.2 Modchip and they don't have problems playing that backups. Need the V5-PNP KEY-non soldering modchip some patch in the backups? Where I can find it? Thanks!
