ASM-Interpreter DS

My first application submission for Neocompo!

Nickname: GEMISIS
Project Name: ASM-Interpreter DS
From: U.S.A.
Division: APP
Platform: NDS
Original Enter: Yes
Support Motion: No
In a past NEO Compo this project won in the top 10: No

This is an assembly interpreter written in C for the Nintendo DS.
I created this project entirely from scratch as a way for others to
learn to program in a basic assembly language in a portable manner.
Using the top screen of the Nintendo DS/DSi, you can view the
memory and registers of the interpreter live. Using the right arrow
key, you can go through your program line by line and watch it update,
or you can press the B button to have it perform your full program
without any pauses. I have included some simple test files with
this program.

Controls:

A for confirmations, B for canceling.

When running a program, press B to run the program all at once, or use the right button on the DPad to go through command by command.

The keyboard can be used to type in filenames, as well as arguments. Argv is supported as well!

The download link can be found at https://github.com/gemisis/ASM-Inter...reter%20DS.rar
For those interested in the source code, it can viewed at https://github.com/gemisis/ASM-Interpreter
There is a compiled version there and attached here on this post. Enjoy!
