Title: Guitar Hero Emulation Lines (R3 & R4)
Post by o12 on 05/22/10 at 19:18:39
Hi,
So in the current design lines 15-28 aren't being used for anything, right?  Are resistors R3 and R4 purely optional, or do lines 15 and 16 on the GBA connector really need to be pulled to ground?

Also, the instructions specify "2K7ohm" resistors.  Should that read "2.7 KOhm"?

I am pretty sure R3 & R4 are required to make the DS think a guitar hero cartridge is inserted.  Pin 25-28 are not used for anything at this point.

2K7 stands for 2.7K and is correct.  Surface mount resistors use this labeling scheme.

You are right with the description of both resistors. The guitar hero lines are not used at the moment but it makes sense to install both resistors for future updates of the occ.
