flycast NVMEM - UNLOCK BOSS

Hello, everyone, I hope you're well. I would like to know if there is any .nvmem or method available to unlock the secret characters from the KOF XI and Samurai Shodown VI games. If you can help me with any information, I would be very grateful.

Thank you very much in advance!

KOFXI - unlock Shion and Magaki Samurai Shodown VI - unlock Kuroko

It would be wonderful if this happened.

Sorry about that. I asked around but got no answer. Still asking...

There is a ROM from this KOFXI that runs on the old Makaron EX emulator super well but it doesn't run on the flycast. The game even boots and starts but very slow and with very slow sound and you can even see the selection, select the bosses but the game is unplayable.

For unlocking Shion and Magaki, I referred to this.

The above problem exists with the naomi conversion, but it seems to be fine with the DC conversion. However, since it was expanded to a read-only address in memory, it could not be accessed directly, and the rom image had to be rewritten.

There is no information at all regarding unlocking Kuroko, so I don't know.

I was told that Kuroko is a console exclusive.

I'm not sure if it's appropriate to include this as a cheat, but I tested the following code and it seems to work fine with kofxi.

cheats.cpp

else if (gameId == "THE KING OF FIGHTERS XI") {
	cheats.emplace_back(Cheat::Type::setValue, "unlocked boss", true, 16, 0x0006665a, 0xe2ff, true);
}

Flycast doesn't include any cheat apart from widescreen ones and cheats that are required for the game to work. However this can be added using the Cheats UI. The equivalent GameShark cheat would be:

"action replay" = "gameshark" ?? (Hexa) "Codebreaker" = "raw code " ? (Hexa) It:s good ? And .cht structure = binary code with structure "cht" ? Right ? For ".cht" , just raw (hex) convert to binary ? Right ? But hmm strange , flycast "core" use gameshark/ar code ? Or use directly binary code ?

My english is low...

The term "gameshark" bothers me, is it really similar to "action replay" code? "gamshark" (cdx or v3.3) .... And "codebreaker" to -_- je comprends is raw , for prefix "01" .

I understood the .cht structure but has it become a standard? like for .dat? because retroarch does not provide any documents on the structure of .cht, (you don't have to be an idiot to understand it quickly but hey... I would have saved a lot of time and in my native language.)

.... "core" emulators only eat binary now that I think about it... if I look at a certain libretro database. -_-
