Is there anyway I can create a .dat file from a rom?

[LunarLoveLust]

Sorry if this is offtopic/illegal ect not sure if it is...

Basically, I have an emulator that needs a .dat file to load each game. The problem is that there are sometimes multiple versions of each game. I'm trying to find a program or something that would give out information of my particular rom, similar to this...

System: NEO
RomName: sengoku3
Game: Sengoku 3

[Program]
261-p1.bin,100000,200000,5B557201,1

Howard has a link to datfile maker on his site....

http://www.oscarcontrols.com/lazarus/

go to the other downloads section and pick misc utilities.... there should be one there.
It worked for me making a dat file for the few genesis roms i had so this may help you.
