Mystery GBA SP EXT.2 cable
« on: December 20, 2022, 11:50:42 pm »
Went to a Goodwill and looked through their bin of assorted cables on Monday and I found what looks like a link cable for a GBA SP. I'm specifically saying GBA SP since both ends of the cable have the same type of connector that the charging cable and headphone jack adapter have that go into the SP/original DS's EXT.2 port. It can't be for link cable stuff since the EXT.2 port isn't wired for that, just power and audio. I thought that maybe it could act as a sort of jumper cable to use another GBA SP to power your GBA SP as dumb and pointless as that'd be, but I got no reaction from either of my SPs when I plugged the cable into both. Looking at a pinout for the EXT.2 port doesn't seem to help much. This cable has four pins: detecting headphones, one side of audio, 5.2V power, and ground. Both ends have the same pins. Does anyone have any ideas what the purpose of this cable is? Does some other electronic device happen to have the exact same port as the GBA SP/DS?

I'm almost 100% positive that cable came with this accessory: https://www.amazon.com/Pelican-Accessories-DS-Battery-Charger-Nintendo/dp/B0009SRZ7Y
I used to have this exact accessory (or something like it) and what you did was you plugged your DS charger into the battery pack charger, and it came with a male to male-cable-that connected from the battery pack charger to the DS so you could charge a battery in the dock and the internal one in the DS at the same time. The amazon customer reviews on this product are a bit vague, but they seem to echo this sentiment. If I recall it didn't work very well, but I haven't had the item since 2007 or 2008, so it's been a long time at this point.

EDIT
Someone is selling one on Facebook Marketplace: https://www.facebook.com/marketplace/item/8211408898932475/
It has a picture of the back of the box showing that it came with the male-to-male cable for DS/GBA SP

Wasn't expecting to find the answer so quickly! Thanks!
