what link protocol does this use for the multiplayer modes? can you create more multiplayer software like this?? even a simple pong?
This uses the basic Cable Link protocol from GBDK (4.5.0), so I think that, technically speaking, any game created with GBDK could support Cable Link with sufficient skill and knowledge. Puzzle and strategy games are easier to implement than arcade and action games because there is more time available to synchronise data and you can afford a small amount of lag. Thank you for your comment!
