How do you edit rfe, mis, dat, ffn, rdf files in the data.gob file?

[heathrf1974]

I'm trying to alter the difficulty level in the World Cup. It seems the World Cup level is more difficult than a single game. I'm also trying to increase the levels of team performance. Five levels doesn't seem enough to me. I was wondering if there was a way to open the files rfe, mis, dat, ffn, rdf in data.gob. To see if I can alter both the number of team performance levels and the difficulty level in world cup.
Does anyone know how to open and edit these files?

Thanks.

I know how to do it but I'm not all that good at making tutorials I'll try and write one up for you tonight.
