.dat files?

I found a .dat archive that I'm eager to crack, but I have no idea where to start. It contains some files for a stupid game engine, RM2K, that I will do almost anything to acheive. Can anyone give me some advice? I will let you play around with the file if you need to

Send me the file. I'll putz around with it... I sucessfully made Command And Conquer fucked up... I mad all guys fire missles... and a whole crapload of other stuff... it's really neat. Just zip and attach it to a post.

Sent the link to you in a PM.

If anyone else wants to try, just reply here. I will be infinitely thankful if you can help me out.

Thanks... I shall see what I can do...
