Emulator Zone
There is no way to avoid learning about the best ROM resource, Emulator Zone. Although most people use it to download various types of emulators, Emulator Zone also hosts a library of ROM files.
The site also has a strict policy of only displaying legal information. As a result, any illicit materials and questions about acquiring them are removed immediately.
Of course, this is the primary reason that downloading ROMs from this platform is absolutely risk-free. The website contains a variety of ROM files for various platforms such as Neo Geo, Sony PlayStation, WonderSwan, and Nintendo.
However, when it comes to games for all of these platforms, the database is somewhat underwhelming. The variety of emulators remains vast, but not of ROM files, which is why you may prefer other sites over this.
