Lol. Well I can tell you My Origonal Red, Blue and Yellow All work fine, non dead battrey yett. and my Gold silver and crystal are all internally dead and require new battries. The GBC Mega memory card saves it to the device only and can reload the save to your cartrige one you replace the battrey. It is soley for backing up files not storing to pc. The GB Transferrer II is for storing to pc, however I read many sites and feedback, no one seems to happy with how it saves and backs up pokemon data specifically. Many have reported crashes non saves and erasing of the entire cartrige due to the overjolt of power it gives the cartrige. Sadly no fully efficent way to get GBC to pc is redily avail. And once u played a save on a emmulator it can NEVER go back to the cartrige anyway. Evidently it does something to the save you can only find deep in the code, the cartrige will always reject it for some rzn, me and my cousin tried. I refuse to buy the thing. Mega memory works fine.
hahahah no. No you cannot. If you want to find oue that is working fine or already properly had the battrey replace you have to check each individual decription being sold either "new" or "used" on amazon. buying these games BRAND NEW unopened is upwards of 250$ dollars (and most times internal battery is already dead in factory sealed!). lol Most expensive being new yellow @ 450$...... lol 2$ hahhahahahahahahah Older items get = rarer = $$$$$$$$
