Very Good, but Hard to Compete with SMB Utility

Reviewed By: segwayspeedracer on 25 Aug 2019

Starting off, the app is very good. It is interesting that… from what I can see… you can’t change enemies like SMB Utility, but you can add and delete them. Overall, this gives more flexibility, but takes time to get used to.

The program needs to better label what styles to choose from. Style 1 being the island platforms, Style 2 being mushrooms, and Style 3 being bullet bills may not be obvious.

It is odd that it cannot open my current hacks, when SMB Utility can… which only has the Luigi Jump ISP and Reverse Pipes + Red Plant patches installed. I also did a lot of rearranging on pointers, enemies and block positions in those hacks. I am not sure which, if either, of these changes caused the program to fail to read my hack, but people should keep those things in mind that it may be limited on what games it can modify if people are hoping to stack patches.
