![]() It would be lovely if there were a widely-accepted way to bundle this kind of board-configuration data with individual games so homebrew and ROM hacks would just work out-of-the-box, but there isnt yet. ![]() Unfortunately, because all widely available game dumps are in iNES format, and almost all emulators only support iNES format, its been very difficult to move to anything else. ![]() Worse, because different people all over the world were dumping NES games as quickly as they could find them, they would each allocate mapper numbers individually: sometimes a given mapper number might mean different things according to who originally dumped this particular game, sometimes multiple mapper numbers actually describe the same board configuration. The iNES header dates back to the very earliest days of NES emulation, when almost no NES games had been dumped or emulated, and we didnt really even know what information was relevant.įor example, the basic iNES 1.0 format can only represent 256 distinct mappers, and the NESFamicom library contains way more than 256 distinct circuit board configurations, especially once you include all the Famicom pirate games, and circuit boards that may or may not have particular components soldered on. Thats just a wire on a circuit board, it doesnt appear anywhere in the dumped data, but you need that detail written down to emulate a game. ![]() Then modify that file as explained by OP for every romhack when necessary.įor disc-based consoles, you can dump a game disc and be sure you have absolutely all the information required to emulate that game, because its impossible for a disc to contain anything but data.įor older cart-based consoles like the GBA, you can dump a cart and have most of the information you need to emulate that game sometimes theres things in the cart (like a sunlight sensor or EEPROM save storage) that is not strictly speaking part of the data, but usually theres enough clues in the data that the emulator can figure something out.įor even older consoles like the NES, dumping a cart will give you some of the information you need, but absolutely not enough.įor example, theres a super-important configuration option called mirroring that is controlled by wiring together two pins on the NES cartridge connector. So instead I would recommend downloading this file: and pasting it in your System folder.

You can use ucon64 to scan a ROM to find its internal crc and sha1 checksums. So, all you have to do is create the entry in NstDatabase.xml, which goes in the location where the system directory is configured in Retroarch.Īn example hack, which crashed, and with this section added to the end of the NstDatabase.xml file (before ). It turns out that nestopia doesnt read iNES headers for some reason, but instead requires the NstDatabase.xml to identify certain ROMs, and ROM hacks will be absent from this file.
