* Add credit to ne.hexpat * Add many changes to nes.hexpat * Fixing dependance on variables declared in if statement * Added mappers and inline to NES 2.0 header, removed needless parenthesises * Add files via upload * Add files via upload * Create nsf.hexpat * Used full name of the SNES on description * Add SNES, NSF & NSFe, new description for NES * Removing erroneous condition in ips.hexpat's truncatedSize * Removing unnecessary std.string import in ips.hexpat * Added both locations for sections in PE, clearer variable names, reorganized DOS stub * Delete patterns/nsfe.hexpat * Delete patterns/nsfmetadata.hexpat * Added chunks from NSFe to NSF * Added NSFe * Fix size of truncatedSize in ips.hexpat --------- Co-authored-by: Nik <werwolv98@gmail.com>
