![]() ![]() If the version bits are 01 or 11, then treat it as if flags byte 1 is entirely zero.įor trainers: If there is a trainer set, treat it as follows: If the version bits are 10, it is NES 2.0 format, and all CRC32 checks for improper headers and so on should be disabled. If the version bits are 00, it is standard iNES format. Whats more what would happen if said ROM did use UOROM and it tried to switch to a non-existent bank?Ĭall the bit3 and bit2 of flags byte 1, the version bits. What about a Mapper 002 game that has 192kB of PRG? I'm not saying that a game like that exists but it would break any code that check the size of a ROM to detect board. This is a method that could be/is employed to determine which board/submapper is being used but I would rather get the information from the header. Mapper 2 - 128kB Size - Most likely UNROM Mapper 2 - 256kB Size - Most likely UOROM The point that I am trying to make is, I would like to be able to use a bit in the iNES 2.0 header to determine which board/submapper is being used. Just to clear things up here a bit I asked if the iNES 2.0 header that appears in the wiki was OK to use and it is, cool. Plus what if they use GoodTools to validate the header again the new information would be lost. I am fully aware that a computer program could be written to go back and update all of the 1.0 headers to 2.0 but that would be a big task and of course it would only affect the ROMs of the people who actually use it. Nintendo wasn't sloppy when choosing which board to use for which game. Which one is your favorite? The fact that a website would list them as both equal with only a 0.1 difference has me interested in knowing your opinion.I not questioning why Nintendo used certains boards for certain games thats obvious. Still since i came across them both, they have been tied by many as equal, but i wanna know what the public thinks. It also says that "it is an all-encompassing version of the FCEU emulator that provides the best of all worlds for the general player, the ROM-hacking community, and the Tool-Assisted Speedrun Community." To me it sounds like the definitive nes emulator for the internet. Besides using it on those things, the pc emulator isn't anything short of what it can do and even the website has the latest version 2.2.3 six months after the most recent version of nestopia UE 1.47. But FCEUX is common among many console homebrew ports like wii, gamecube, and others that may been noticed if you have modded CFW stuff. Just to add a bit of info, I been using Nestopia as primary PC emulator for years, is lightweight and reliable and useful for common use and rom hacks, even comes with a ips patcher, various nes controller accessories, some other nice things. The concept behind FCEUX is to merge elements from FCEU Ultra, FCEU rerecording, FCEUXD, FCEUXDSP, FCEUXDSP CE, and FCEU-mm into a single branch of FCEU.Īs the X implies, it is an all-encompassing version of the FCEU emulator that provides the best of all worlds for the general player, the ROM-hacking community, and the Tool-Assisted Speedrun Community. Over time FCE Ultra had separated into many distinct branches. For pro users, FCEUX offers tools for debugging, rom-hacking, map making, Tool-assisted movies, and Lua scriptingįCEUX is an evolution of the original FCE Ultra emulator. The FCEUX concept is that of an "all in one" emulator that offers accurate emulation and the best options for both casual play and a variety of more advanced emulator functions. It supports both Windows and SDL versions for cross compatibility. It supports NTSC (USA/JPN), PAL (European), and NTSC-PAL Hybrid modes. TheĬross-platform build now requires OpenGL 3.2.įCEUX is a Nintendo Entertainment System (NES), Famicom, Famicom Disk System (FDS), and Dendy emulator. There is experimental supportįor NES 2.0 submappers, which may or may not be 100% correct. The APU desync bug being (hopefully) fixed. The biggest things worth mentioning are the OS X port and This is still geared towards nerds, but I hope toĮventually make it palatable to the masses.ġ.47 is out. More or less perfectly, there is no GUI and you should install dependencies It is still very rough, and though it does work Just to add some clarity about the OS X release: it is currently not planned Do not expect it to be perfect or even good, but if you're curious it I have released an alpha-quality Windows binary based on the cross-platformĬode. Support for new platforms, and bug fixes in the emulator core. Nestopia UE (Undead Edition) is a fork of the original source code, withĮnhancements from members of the emulation community. Nestopia is a portable NES/Famicom emulator written in C++. ![]()
