Refer to the last tutorial for a bit more info. The mapper number is an identifier of what memory management logic is used onboard.It contains the CHR and PRG ROMs as well as the security chip (aka the CIC) and an memory mapper. Examples are UNROM, CNROM, TSROM and TLROM. The PCB type is an identifier of what chips are supported on the board.We strip off this header when we split the ROM later on. This header is used by emulators (not by the NES itself) to figure out what mapper to use. NES files that identifies the technical components of the ROM. An iNES header is a few bytes at the beginning of all.Let's take a minute to wade through all this NES mapper/header/PCB terminology. It doesn't really matter to us why it's more complicated, but it does result in the ability to use higher capacity ROMs. This tutorial covers games that use the MMC3 memory mapper, which is more complicated. In the other tutorial, this chip was a simple 74LS161 binary counter: each strobe of one of the signals from the NES to the cartridge advanced the selection by one page. The NES only has 16 address pins for the program and character ROMs (referred to later as PRG and CHR ROMs) so there is a chip on board that lets the game access higher memory addresses. Ok, so what makes this the advanced tutorial? The fact that we are using a PCB with a more complicated memory mapper. Although I'm not sure of the exact reason that this game wasn't released in North America, I would assume it was because of the declining volume of NES games released here after the introduction of the Super Nintendo in 1991. Released in 1991/1992, this is one of the later NES releases. I'm going to make a reproduction of Takara's Banana Prince.īanana Prince, originally released as Bananan Ouji no Daibouken in Japan, is an interesting platformer by Takara. original won't work)Īnd essentially any other MMC3-based game, with a few exceptions here and there. 2 The Lost Levels ("Loopy's MMC3 Hack" ROM. This tutorial is a good guide for making: Please don't do this, and if you're making a reproduction, please include a line on your artwork that identifies it as a reproduction, so if you trade it away it isn't mistaken for anything authentic. Sadly, people in the past have used this method to make counterfeit copies of prototypes or rare games like Stadium Events. Gives you a chance to be creative in the label making process.Gives you some of the tools necessary to get started with ROM hacks or homebrew.Adds a one-of-a-kind item to your collection.Experience games that have never seen a release in your region, games that never saw the light of day at all, and homebrew games not licensed by the original manufacturers.Play games on authentic hardware to eliminate errors or inaccuracies of emulators.If you've read my Basic NES Reproduction tutorial, you'll likely experience a little Deja Vu, as I would like to make this tutorial as complete as possible, and I'll probably copy a few paragraphs over. Today I'll be tackling another reproduction, this time using a more complicated PCB.
