2 Add BIOS requirements to the table?

Some libretro cores require BIOS files to work, and those BIOSes must be placed in the system folder (with each BIOS being a binary file). Currently you will need to find those BIOS files by yourself as it may be illegal to provide them bundled with each libretro core that needs the. For example, since all PlayStation emulators, like Beetle PSX & PCSX ReARMed, (as well as some other libretro cores), require a closed source BIOS file to work, these BIOSes are usually considered to be in an legal gray-zone and can be a little difficult to aquire, at least legally. Those BIOSes must be placed in the system folder on your emulator software (libretro core in this case).

This linked table lists all the required BIOSes which some emulators requires, so if a systems BIOS is not listed here then it means that it does not require a BIOS file.

Remember, since Linux is a case sensitive system, you have to rename the BIOS files according to this table so that the libretro cores will be able to find the BIOS files.

Note that most of these BIOSes are not revered engineered releases but binary ROMs ripped from the EEPROM inside of an actual game console system hardwarre, so it is proprietary binary blobs (precompiled software binaries) which might still be under copyright depending on the console age and origins. It may be that some of those BIOSes are can be seen as Fair use since these game consoles are no longer sold and there is probabably no commercial value of them, but that is something that the XBMC Foundation need to talk about with attorneys about before being able to distributing such BIOS files as resource add-ons or bundled with each libretro core in an official repository.

2.1 Example of BIOS requirement table

BIOS requirement table

The table below lists all the required BIOSes which some emulators requires for each each emulated system, so if a systems BIOS is not listed here then it means that it should not require a BIOS file.

Warning! Linux is a case sensitive system. Please name BIOS files exactly according to this table.

3 Acceptable to link to sites with BIOS files in wiki or?

See above discussion, it it OK on this wiki page to link to sites like http://emulation-general.wikia.com/wiki/Emulator_Files which in turn contain links to the BIOS files with MD5 values or maybe even OK to link to the files directly? Gamester17 (talk) 08:00, 22 December 2015 (EST)

  • There is first the gray area of abandonware if the publishing company does no longer exist or care about the copyright of the BIOS file from old video game consoles which can be used for emulation. Gamester17 (talk) 04:27, 26 July 2017 (EDT)
    • I guess that otherwise the legality of hosting and maybe even direct linking non-reversed engineered binary BIOS files might depend if copyright still applies and in which country the actually files is hosted as well as how old the original code is, as different countries have copyright lengths. Copyright Law (Berne Convention to be precise?) is different in different countries right? A few countries have example have a copyright expiration data of 25 years from publication/completion, which would cover a lot of the old video game consoles. Will a copyrighted code get into public domain once its copyright expires? If copyright in practice ever expire, since in the United States for example the fairly recent Copyright extension act, the new term is 95 years or author's life plus 70 years, whichever comes first. So according to current US law, no software created since the popularization of the personal computer will become public domain before 2050. And very little of it before 2070. But if that same was also published in a other country which have different copyright laws or at least different copyright expiration dates. Gamester17 (talk) 04:27, 26 July 2017 (EDT)
