NAME Games::NES::ROM - View information about an NES game from a ROM file SYNOPSIS use Games::NES::ROM; # Read in the ROM without having to know its format my $rom = Games::NES::ROM->load( 'file.nes' ); # Specifically read in an iNES file $rom = Games::NES::ROM::INES->new( filename => 'file.nes' ); # Access the details print 'PRG Banks: ', $rom->prg_count, "\n"; print 'CHR Banks: ', $rom->prg_count, "\n"; # etc... # View the SHA-1 & CRC checksums print 'SHA1: ', $rom->sha1, "\n"; print ' CRC: ', $rom->crc, "\n"; DESCRIPTION This module loads the details of an NES rom file. It is primarily meant to be used a base class for more specific file formats. Those formats include: * Universal NES Image File (UNIF) * iNES INSTALLATION perl Makefile.PL make make test make install METHODS load( $filename ) Attemps to read the ROM structure into memory using all available file formats until success. prg_count( ) Returns the number of PRG banks for this ROM. chr_count( ) Returns the number of CHR banks for this ROM. sha1( ) Returns the SHA-1 checksum for the PRG and CHR data. crc( ) Returns the CRC checksum for the PRG and CHR data. sprite( $chr_bank, $index ) Returns the raw (composite) sprite in the specified CHR bank at the specified array index. BASE ATTRIBUTES The following base attributes are available for all file formats: * filename - The filename from which data was loaded * id - A string found at the beginning of a file to identify the file format * title - The game's title, if available * prg_banks - An arrayref of PRG bank data * chr_banks - An arrayref of CHR bank data * has_sram - Boolean value to determine if the ROM is battery backed * mapper - A value indicating what memory mapper to use with the ROM * mirroring - A value indicating what time of mirroring is used in the ROM NOTES * mapper - iNES uses integer IDs, UNIF uses string IDs * mirroring - An integer ID, using the UNIF list as a basis Each file format will have an extended set of attributes specific to its data structure. Please consult their documentation for more information.
