Types

type DB

type DB map[string]RDB

DB is a database that contains many RDB, mapped to their system name

func (*DB) FindByCRC

func (db *DB) FindByCRC(romPath string, romName string, CRC32 uint32, games chan (Game))

FindByCRC loops over the RDBs in the DB and concurrently matches CRC32 checksums.

func (*DB) FindByROMName

func (db *DB) FindByROMName(romPath string, romName string, CRC32 uint32, games chan (Game))

FindByROMName loops over the RDBs in the DB and concurrently matches ROM names.

type Game

type Game struct {
	Path         string `json:"-"`
	Name         string `json:"name"`
	Description  string `json:"description,omitempty"`
	Genre        string `json:"genre,omitempty"`
	Developer    string `json:"developer,omitempty"`
	Publisher    string `json:"publisher,omitempty"`
	Franchise    string `json:"franchise,omitempty"`
	Origin       string `json:"origin,omitempty"`
	Rumble       bool   `json:"rumble,omitempty"`
	Serial       string `json:"serial,omitempty"`
	ROMName      string `json:"rom_name,omitempty"`
	ReleaseMonth uint   `json:"release_month,omitempty"`
	ReleaseYear  uint   `json:"release_year,omitempty"`
	Size         uint64 `json:"size,omitempty"`
	CRC32        uint32 `json:"crc32,omitempty"`
	System       string `json:"system,omitempty"`
	MD5          string `json:"-"`
}

Game represents a game in the libretro database

func (*Game) SetField

func (g *Game) SetField(key string, value string)

SetField sets a field in the entry

type RDB

type RDB []Game

RDB contains all the game descriptions for a system

func Parse

func Parse(rdb []byte) RDB

Parse parses a .rdb file content and returns an array of Entries
