/* The romdatabase contains the items mupen64plus indexes for each rom. These
31
* include the goodname (from the GoodN64 project), the current status of the rom
32
* in mupen, the N64 savetype used in the original cartridge (often necessary for
33
* booting the rom in mupen), the number of players (including netplay options),
34
* and whether the rom can make use of the N64's rumble feature. Md5, crc1, and
35
* crc2 used for rom lookup. Md5s are unique hashes of the ENTIRE rom. Crcs are not
36
* unique and read from the rom header, meaning corrupt crcs are also a problem.
37
* Crcs were widely used (mainly in the cheat system). Refmd5s allows for a smaller
38
* database file and need not be used outside database loading.
