Hi yzb, thanks for sharing this. I'm really excited to try it out, but I need to put together another 32MB Dreamcast first. Once I finish a couple of other projects...
I'd love to hear more about the changes you had to make to get this working. And do you think your methods would work on other games, at least other KoF versions?

Bios tested, jc's 32M bios cannot be flashed on the va1 motherboard. I don't know why, it will automatically restart, so jc's 32 bios can only be flashed on the va0 motherboard
Regarding the game, it cannot be a wince game, other games should be able to use this method. However, the source code of the game has to be modified a lot ASM, so it takes a lot of time
In addition, I personally think that dc is already very fast in reading data, and many games do not need to use 32M memory (with gdemu can reach the limit)
Because my friend likes kof98 and changed the 32M dreamcast, so I studied this game
Regarding this 32M kof98, I will add another explanation, because at the beginning, because 16M files are pre-read into the memory, the reading time of 15-20 seconds will be black at the beginning (gdemu uses 5 seconds)
In addition, I don’t know if it’s a bios problem or other problems. It will stop working when playing sfd cg, so I skipped this paragraph in the game and went directly to the title screen of the game.
