Wow. Haven't been here, in, what, 10,000 years? (Not been using RPG Maker lately)
Seems like good progress on your game so far.
And I decided I'm too lazy to make sprites for you. But if you need x and zero from any megaman game, then try
http://megaman-sprites.netThats where I went to get srpites for my game(MY GAME MAKER GAME!)
I'm think that that tournament idea is pretty neat.
In Legend Retold, a game of mine for rmxp, there was a torunament where you fight all the rtp main characters(arshes and stuff), which your idea reminded me of.
And also, what is your games current file size after resizing those WAVEs?
