FC red and white machine game flash card Mapper0

Introduction: For proofing thickness, you need to choose 1.2mm FC red and white machine game burning card Mapper0. The board is being printed and has not been verified yet. You need to cooperate with kazzo to burn the game.

The FC red and white machine game burning card Mapper0
is being printed and has not yet been verified. It needs to cooperate with kazzo (click here to go to the kazzo project) to burn the game.
 
 
 
Proofing has been completed on 2022-01-22. One problem has been fixed. If you need proofing, please Use mapper0 to temporarily test the subsequent four-in-one and four-in-one experimental cards.
The proofing thickness needs to be 1.2mm.
MAPPER4 can also be used directly. Just search it in Kaiyuan Square.

KAZZO FC red and white machine game card dump burner

Introduction: KAZZO fc game cassette dump tool
1. Full-pin components, the difficulty of welding is reduced (the interface is patch type-c);
2. TYPE-C interface, mainly because the data cable is hard to find now, you can change it yourself if you don’t like it Pin usb interface;

1. Full-pin components, the difficulty of welding is reduced (the interface is patch type-c);
2. TYPE-C interface, mainly because the data cable is hard to find now, I don’t like it You can change the pins of the USB interface by yourself;
 
if you have any questions, please leave a message. I am also trying to make an FC cassette.
 
The verification has been completed on 2022-01-15 and the following problems were found;
KAZZO uses ver0.1.3, and the host computer is anago. It can dump and write normally, and requires the cooperation of the cassette;
the LED light is not used, the original circuit does not have an LED, this LED It was added with reference to Laomei, but there is no Laomei firmware. Those who understand the source code can add it by themselves;
the above required files can be found at https://zh.osdn.net/projects/unagi/wiki/kazzo_intro_en.
