I have only messed around with the MMF2 demo because I am waiting to buy MMF3, but I think they should add a "build nintendo DS" option. NDS homebrew is the only community that can compare to this one. They should combine the two communities into one giant, awesome, indie game developer network! Also, there is Java for NDS already, and I heard MMF3 will be written entirely in Java, so MMF + NDS just makes sense!
Whoopie! You took super-mario-mega man and made ninja-may-cry. Good job! You are now the supreme master of unoriginality!
The ability to have the game parse through code to find all instances of XXXXX string, for example, usages of "alterable value A" conforming to conditions- including code snippets and function calls. And then, to make it valuable, the option to edit and replace these functions via script. So for example, I could write a simple line of code that would iterate through my program, replacing all instances of "Alterable Value A("Object1")" with "Alterable Value B("Object2")".
