Re: Problems connecting GBA-Gc
Well, for one thing, there's no such thing as a PAL GBA or NTSC GBA cartridge; the GBA and all games are multiregional, and can work with each other despite language differences.
As for the problem itself, I'm not entirely sure. Sometimes, when connecting my Ruby cartridge to PC, it gets an error. I've found that this happens when having certain Pokemon in my lineup (ie. Latios, for one). I'm not sure why, but it always causes errors when Latios or other certain Pokemon are in my Team (Not all Legendarys BTW. One or two normal Mons also cause this error). Try switching your Team around and retrying the connection.
Also, to anyone reading this, I have never once used a gameshark or cheating device of any kind. If anyone can shed any light on why these errors occur with certain Pokemon, then please do (Yet I'm sure that all Pokemon should be allowed to connect with PC).
As long as we continue to fight, and destroy, we are forever prisoners of our ignorance and foolishness; true 'freedom' does not exist
