Hi! I downloaded the GoodGEN datfile and use it with clrmamepro. Well, it works, but spent several hours!

I´m using single file dat and my PC is a Athlon XP3000 with 1GB RAM and a SerialATA HD (I don´t believe that it could take so much time!)

Actually I have around 1000 Roms for Sega Genesis. I have a complete set for MAME 0.78u5 (4754 roms) and it spent few minutes to do a complete Scan, I also have almost a complete set for Atari 2600 (2861 roms) and it spent few minutes also.

I´m doing something wrong, or there are some hard process with these roms?
