BrainFox

BrainFox is a Brainfuck interpreter that can be run on your GB (or emulator).

It allows to write a program of 7200 comands length (program memory) which operates with up to 5000 memory cells (data memory).

Here are all brainfuck commands:

Character	Meaning
>	Increment the data pointer (to point to the next cell to the right).
<	Decrement the data pointer (to point to the next cell to the left).
+	Increment the byte at the data pointer.
-	Decrement the byte at the data pointer.
.	Output the byte at the data pointer.
,	Accept one byte of input, storing its value in the byte at the data pointer.
]	If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.
[	If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
	(Space) Does nothing, can be used to make program more readable, but still takes place in program memory

And how to work with BrainFox:

Keys	Meaning
D-pad	Enter < > + - commands
D-pad + A	Enter [ ] . , commands
D-pad + Select	Move cursor
B	Delete previous symbol (like Backspace)
Start	Run/Stop the program
Start+Select	Clean program memory (do it when you run BrainFox the first time)
