But unfortunately, after trying for 15 years, I've not been able to come up with a stable, simple format for every system in the world that doesn't rely on emulator-specific design decisions. True preservation requires games include a detailed description of the entire PCBs of these games, not just the ROM chips. There are even cases like Mega Man X (Japan), where they made a mistake with the copy protection, and to fix it, resorted to wiring a resistor right onto the back of the PCB of every cartridge released to change the memory map.Īnd databases + heuristics fall apart when it comes to homebrew, fan translations, ROM hacks, etc. If I had to name one, I'd say the Neo Geo Pocket is one. There's very, very few cartridge-based systems where only the ROM dump is all you need. Developers wised up and started including fake strings to fool them, so once again.
#BSNES NOT SEEING ROMS CODE#
Example: "if the ROM is larger than 2MB, and has save RAM data, and has 32K bank granularity, then map the save RAM data to a smaller area of memory." Rather than "if the game is Fire Emblem, treat it differently than Ys 3."įor the Game Boy Advance, emulators and flash cart tools will scan the ROM looking for signatures from code libraries from Nintendo that handle save memory, like "FLASH512_V", "EEPROM_V", "SRAM_V", etc. SNES emulators in the past have been able to add bizarre tricks that just so happen to line up with the existing commercial games to not need a database, but it really turns out to be a mini database disguised by being obtuse. So using that information is not enough for many titles, and so you need a database for those titles to work properly.įor the SNES and Genesis, the games have internal headers that tell you most of the details of the games, but not enough for complete emulation. We do not allow asking for or sharing ROM downloads or any piracy (Rule 1) I am a bot, and this action was performed automatically.
#BSNES NOT SEEING ROMS ISO#
If you are looking for ROM or ISO downloads, this is not the right place.
People stick a fan-made "iNES" header at the top of the ROM data, but they made the format before all the details of the NES were known. Due to an apparent limitation in BSNES, RocketLauncher cannot see when the emu has loaded any game with '. Here are some quick answers for some commmon questions: -If you are looking for emulator download links please check out our wiki.
If you're talking about the NES, sort of yes. Nothing about the carts are preserved in the ROM images, and you need a per-game database, or you'll need some kind of "cartridge type" list that the user has to choose from when booting the game. If you're talking about an MSX game, then yes.
