Ah well!

Someone on the Internet suggests it only provides 5v with a DMG or GBC game in the slot, but not tested that yet...

Be interested if that makes sense with the GBA midi synth..

i'll get busy with the multimeter and work out what's going on.

thanks!

But yeah some link cables are wired funky which is why I include one in that bundle.

Thanks really useful to know the GBA should be providing power at least as I've modded it so possible I've caused some calamity there.

So if you cut a link cable, you can wire in the power lead.

I'm not sure about the MGB-004 adapter but I'd guess it will work (in fact I swear I've tested it and confirmed that). A quick test with a multimeter should confirm it pretty quick though!

I now have a GBA I wanted to use with it... I assumed using the gameboy pocket MGB-004 adapter cable would work to connect the GBA to the DMG ended lead from my arduinoboy... it doesn't - no power!

anyone know if this is because:

a) the adapter doesn't pass the power?
b) GBA link cables in general never provide power at all.
c) another reason?

trying to work out if I need to build another arduinoboy (which I was halfway to doing already) with external power OR just solder a new lead....

thanks!
