Why so big emphasis on bootleg releases?

I just want to look up for official release of games, but when I look for, let's say games developed by Konami, it gives me bunch of bootleg releases... I think these should not be shown by default.

I think the "Software published by" and "Software developed by" are not completely clear, but:

- Software Published by Konami, is all software that Konami Published (that tab you are looking for)
- Software Developed by Konami, is all software that Konami Developed and is published by Konami and others

So you should look at the "Software published by" for the official releases.
