Hi,
I have a few 2000s-2010s PC game discs from Russian publisher 1C (and a few other similar publishers) laying around, found in local garbage dumpsters so my "collection" grows. Some of these games are not in the database so I want to add them. I only have hardware to dump DVDs, but these discs are mostly DVD anyway, maybe I'll buy CD-compatible drive someday, also I have a few disc-based consoles.
I used checksum databases in the past to organize my files (mostly for roms though) using igir and retroarch.
