A very cool and unique SMB1 Romhack that turns it into a Metroidvania. The catch is that the screen can still only scroll to the right. So all the branching paths and backtracking is handled via Warp Pipes.

This game seemed impossibly hard when I first played it with savestates but I've beaten it legit a few years later and it isn't actually as difficult as I originally thought. The Final Boss pretty impressive because it is giga bowser on NES.

You might wanna draw a map for this game.

Edit: Played it again and actually drew a Map. Was a fun process. To be honest I think this game would be better off with Infinite Lives. Since it's just tedious and frustrating getting back to Area 3 and 4 after getting a Game Over.

Use Game Genie Code: SXGOPO for Infinite Lives :)
