Yes, after the regional information there's an 8-byte ID. I don't know what else it is. Not all games will work with a clean FlashROM or one that's full of...

There might be a bug here. I don't remember which games actually use this call or whether they actually need anything there.

Just found this from Metallic code: ``` struct factory_sector { struct factory_record { // everything 'char' below is decimal numbers in ASCII, unless noted else char machine_code1; // '0' -...

0x8cfe8000 memory with true DMA? I think this is a memory issue. Maybe need shift a bit to 0x8cfe7000 or 0x8cfe6000 for example. But you need to type in manually,...

Try closer to the end of memory: 0x8cfe9000, 0x8cfea000, ...
