Newest gba repros

[alx5962]

I have some gba repros bought few weeks ago I'd like to reflash. Each time I have the "Unknown Flash" error.

Here are the Flash ID codes displayed on the reader: EA3E, EA1F, EA1B, EA3D.

Some seem to use the Intel 4400 chipset, but I don't know how to confirm this. I took a picture of each card, as it may help identify them. Is there a database available somewhere identifying each one of them?

• In case some are using a 4400L0ZDQ0 variant. In the GBA.ino file, flashRepro_GBA() function, do I just replace "8816" with my own flash id codes to test if it works? Or Will I brick them If I do so ?

if ((strcmp(flashid, "8802") == 0) || (strcmp(flashid, "8816") == 0) || (strcmp(flashid, "227E") == 0)) {
...
// Intel 4400L0ZDQ0
   else if (strcmp(flashid, "8816") == 0) {
     println_Msg(F("Intel 4400L0ZDQ0"));
   }

I'm new to this so I don't really know where to look at. Any help would be very appreciated.

I also don't understand this process. It would be great if someone could make a YouTube video on how to do this or something.

Those are ST flashroms. The last picture is MX. The MX29GL128 should work if you add the ID. The STs, I never had one of those so I can't comment. You have to read the datasheets and then write new flash functions accordingly.

Or you can buy a GBxCart RW, it focuses more on writing repros and already supports those chips: https://flashcartdb.com/index.php/Main_Page#Gameboy_Advance_Clone.2FRepo_Carts

A third option would be porting the code from the GBxCart RW to the Cart Reader platform.
