PRG+CHR can be combined for generating the program hash. > Is there an advantage of using sha256($prg.$chr) over separate sha256($prg) and sha256($chr)? īut right now, we're basically omitting chip entirely unless it's a complicated one like an MMC.

In a sense it'd be nice to lose board entirely (except for aesthetics), and set up the board based on what chips it has, but then I don't think anyone is going to emulate a 74LS directly in XML. A lot of these boards are honestly just discrete logic chips in certain configurations. Which would be ugly.Ĭhip type is tricky, too. If all we wanted were magic numbers, we could use a 16-bit value that becomes a specific board+chip size+pinout configuration. I'd rather a descriptive text label than a magic number. My solution is basically to make up names for their board types, eg "BANDAI-FCG".Īnd I know the obvious problem with that: everyone will want to make their own names as well. The big problem with this is that some of these boards are nameless. I want to do away with mapper numbers entirely. My last, and most important, qualm with his format is that it's back to the useless mapper="number" system. All the same, I don't like my name for that, but it is what it is. Defaults to false if omitted so you can avoid the double-negative of nonvolatile="false". So for now, I add nonvolatile="true" to the RAM argument to tell it to be preserved. What the behavior is actually saying is, "this data is non-volatile and needs to be saved between runs." "battery" is a nice argument, but I wouldn't go with "0" or "1", but "true" or "false".Īnd further, it breaks down at the GBA level: FlashROM, EEPROM and FeRAM memory do not have a battery. Next, I try and avoid getting into "describe this memory chip's type or purpose", so "wram" or "sram" would be out. This avoids getting into arguments with SI unit proponents ("Hey, let's call it 131.072KiB!". My size parameters are in decimal or hex notation, but there is no k/m/g modifiers. xml file for your game, you can either check this Wiki to see if the game has been added since the last package, or request cheats.In this example, I use SHA256 because it's harder to fake. Remember, not all games have cheats yet.

These cheats might be compatible with earlier versions. Use the latest version of Nestopia UE (v1.49) or the latest version of Nestopia (v1.40).

The default cheat folder is your Nestopia path plus "\cheats". You can check by clicking on the Options menu, then Paths.
