hey, i'm honestly sick of posting this kind of crap too, so please don't get mad at me. the thing is, with advances in technology and emulation, i was wondering just how hard it would be to emulate linking either by 2 screens or by netplay. i mean, not everyone has 2 gameboys and 2 copies of each game, and collecting rings in sonic advance 2, racing as yoshi with 4 tracks in mario kart, and playing '83s mario bros. gets old REALLY fast. i was just wondering if playing 4 swords online will ever be a reality. if not, i was wondering if nes emulation on the GBA requires 2 flash carts or not. thanks again, and sorry about this.
