Nintendo DS Modded to Play GB and GBC Carts

Posted by Zonk on from the original-tetris-on-the-DS- dept.

Steve E. writes "Apparently someone has made the first hardware mod to the Nintendo DS. An entry over at the Nintendo DS Livejournal Community gives detailed instructions on how to modify a DS to play legacy cartridges." From the post: "1. Disassemble your Nintendo DS. This step is fairly self explanatory, if you can't figure out how to take your DS apart, you should stop here."

    The Z80 CPU of the GB/GBC is basically built into the silicon of the GBA processor. It has really nothing to do with being a seperate chip of any sort. The modification works because the DS in "GBA Mode" is hardware identical to a GBA. The only other difference is that GB/GBC carts take 5V instead of 3V, which it appears is the main function of the jumper wires in this mod.

    It's likely though that after nintendo burns up their (presumable) back stock or order commitments of GBA CPU's that they will switch to a CPU that does not contain these extra elements and this modification may become impossible.

    I don't want to hear any more non-sense about DS being able to be modded to play GB/GBC games. This is nothing by krap. Why? Well, grounding an already grounded wire and grounding the antenna isn't going to get you anywhere my friends. the pictures where taken from http://www.lik-sang.com/news.php?artc=3530. The voltages do not match between the DS/GBA and the GB/GBC. Remember how the GBA units had a physical switched that was pressed when you inserted a class game? This switch turned off the ARM7 CPU, turned on the Z80 CPU, upped the cart voltage from 3.3v to 5v, and changed the wiring configuration used on the link port. Grounding an already grounded pin on the cart and grounding the DS's antenna, how exactly will that accomplish all of this anyways? ITS NON-SENSE!!!

    The bad news is this story is BS.

    The good news is, you can play GB and GBC games on a DS if you have a flash cart. ...And you can take that to the bank!

    Nintendo DS reads GBA flash carts just fine, so Goomba works as well on a DS as on a GBA. Two caveats:

    • Flash2Advance and EZFA flash carts are ordinarily written to through a cable connected to the GBA's link port. The GBA, GBA SP, and GameCube Game Boy Player have this port, but the DS doesn't. I'd suggest buying the EFA (Extreme Flash Advance), which is written to through a connector on the cart itself. if you want to run PocketNES and Goomba on a Nintendo DS.
    • There exists no publicly known way for GBA flash carts to access any DS specific features. This means you won't see SNES Advance ported to run natively on the DS any time soon.
