I think it would be awesome to see a hack of SMA4 in which all of the e-Reader levels are put into a "World 10' type of thing, that you unlock by completing every level and going to the World 9 warp zone where a warp to "World 10" has appeared. Another idea I had for this hack is that there could be Star Coins which are needed to unlock the individual levels in "World 10." The total amount of star coins for a world would be shown, but not for the individual levels, so that you have to explore the levels to find the Star Coins, although when you get all of the Star Coins in a level it turns golden. There would be different amounts of star coins per level. Also, the multiplayer could be enhanced to where both players play at once, but can explore separately through the level without having to be confined to shared screen space. You could also add Toad and Peach as playable characters and give all of the characters their SMB2 abilities. Peach would be unlocked after beating World 8. Lastly, it would be awesome if there were an alternate version which used the original graphics and sound from SMB3. It would be nice to get rid of the ear rape screech in the castle theme for SMA4 style too. I know all of this is way too much to ask, but it would be nice to see this done, and would easily become the best version of SMB3, if not the best Mario game ever.
