Trouble sorting roms

[MrSumOne]

I'm having some trouble with RomCenter. I'm trying to trim my romset, so I downloaded the dat and header files from no-intro dat-o-matic, which is where my set comes from, and scan my romset: https://imgur.com/b48qlQb. As you can see in the picture, when searching something like "zelda", it comes back with all the regional versions of that game. When I change the search to 1G1R, so that I don't have all these other regions, I get something like this: https://imgur.com/OYu6OsS, where you can see the Zelda 1 (USA) is showing a grey icon, with no other Zelda 1 rom showing green. What am I doing wrong?

This is the normal behaviour. See http://wiki.romcenter.com/wiki/doku.php?id=1g1r

If 1g1r is selected, only one rom per game will be loaded in db, all others will remain unknown and appear in grey.

ps: swith to rc4

I don't understand, sorry! 1G1R should read "Legend of Zelda, The (USA)" and "Zelda II - The Adventure of Link (USA)" as two different games, right? So, as shown in my picture, why is only Zelda 2 showing green with 1G1R turned on?

RC4 gives me this without 1G1R: https://imgur.com/oOl9I80
and this with 1G1R https://imgur.com/YiQmwm2

I feel like I'm missing something simple here...

I figured it out, thanks! RC4 is pretty cool! I'll switch over right away!
