... http://forums.sonicretro.org/index.php?showtopic=26537&st=75 You know...earlier in this topic. (or if you mean the Advance 1 proto) http://forums.sonicretro.org/index.php?showtopic=26646&view=findpost&p=627973
I know this is a huge bump, but if anyone is interested, someone is selling SAdvance2 prototype on eBay which ends in 4 hours. I don't have a GBA anymore so it's pointless in me bidding. I would supply a link but I'm on my mobile. Just search "Sonic proto" and it will come up. Staff, feel free to trash if this wasn't worth bumping. I'm on my phone so sorry if I've missed any details. No idea if it's real or not.
