Very technical question about the DS

DarkPrimus

I understand that communication between Slots 1 and 2 is possible on the Nintendo DS, since there is a GBA-cart "expansion" released for the DS game Daigasso Band Brothers. My question is how exactly the communication between the two carts takes place. Would it be possible for a developer to, hypothetically speaking, have information saved on the DS cart transferred to the GBA cart, and then have the information from the GBA cart transferred again to a different DS cart?

Since Opera uses the GBA cart as a RAM slot, and Pokemon D/P allows for pokemon transfer from the GBA games, I imagine so.

[edit] Now whether or not you can write to an actual GBA (game) cartridge, rather than a specialized one designed for it, is another matter. But keeping in mind that we can already see transfers being possible, and that the GBA cart runs on GBA hardware, I don't see why not.

Anything can be done with the GBA slot and DS slot, including moving data from one to the other, as long as the system is in DS mode. In GBA mode, the DS slot doesn't exist.

Yes, this is possible. Both the Nintendo DS and Gameboy Advance share the same architecture with regards to SRAM, the area of memory that can be written to. Both have 64k of SRAM, and both areas are located at 0x0A000000. Both can store data in any format - binary, text, etc.

So yes, you can read from a DS cart to a GBA cart and vice versa.
