Games::NES::ROM - View information about an NES game from a ROM file
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";
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:
perl Makefile.PL make make test make install
load( $filename )
Attemps to read the ROM structure into memory using all available file formats until success.
Returns the number of PRG banks for this ROM.
Returns the number of CHR banks for this ROM.
Returns the SHA-1 checksum for the PRG and CHR data.
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.
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
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.
