I usually turn on my GBA anywhere outside my house. And I'm serious. The only downside is that, in Brazil, GBA cartridges can be almost $100, so, to buy one, you must save much money (take me for an example: my father gives me R$ 50,00 per month, which means -> almost $20,00 per month -> which means I have to save my entire money for 5 months to buy 1 cartridge.) Sad, isn't it?
