It was a long time I wasn't here (since 2004-2005), glad to see you are always here

I'm checking my actual contents with DATS for NES and I see a little problem for some roms (66 for me). I'll take an example:
For the game named "2 in 1 Lightgun Game - Cosmocop + Cyber Monster (Asia) (Unl)", for ClrMame dat, the size is 131072 (correct) and for RomCenter dat, the size is 131166 (incorrect).
Someone have an explanation for me? I'm using RomCenter.
I attach a txt file with all games with this problem for me (if this can help)

Many thanks.
PS: I hope I'm posting in the correct forum
