This is a fully functional Brainfuck interpreter and compiler. The Famicom Keyboard is required to use this ROM.

There are a few example programs included with the ROM. The first is a Hello World program that just prints out that text. The second is an echo program that will echo back what is typed. This second program was used to debug and verify the engine and keyboard.

There are two other programs in the ROM and I forget what they actually do.
