no, no. thank YOU.
i was totally actually wondering.
wow, thanks to your reply everything seems so clear now.
like dinoh said lol the picture is a 2010 meme lol.. this is a joke cartridge... some cases it doesn't even have a game in it... (or someone just put a sticker on a true mario cartridge and is selling it for lulz)
as for identifying a bootleg (a fake cartridge) you see in the TOP where it just says "GAME"? that's the obvious sign for bootleg copies
a real cartridge would had said "game boy" or game boy colour (depending on the console), but never just "GAME"
the cartridges that has "GAME" on them, are fake copies you could get on sketchi small stores (usually owned by a chinese\indian\arab\indian guy) you could get theese cartridges for cheap, and there were loads of "999999999 in 1" catridges (which just have 4-10 games with a menu repeating them all over)
all of them had the "GAME" in them, probably i guess because "GAME BOY" is a trademark and they could get in real trouble
keep in mind, this tip is only to identify hacked games\bootlegs
there are fake copies which you can barely tell the difference between a copy and a fake, if you are looking for example pokemon games, there are really good copies out there, and the only way to know if it's a fake it's looking at the PCB
