Executing ARM Jazelle (JVM Bytecode) on the Wii's Starlet (github.com/thamugadi)
This Wii homebrew executes ARM code on the Starlet with Palapeli's exploit, and uses it to set the Starlet in Jazelle mode. It then jumps to the JVM bytecode specified in bytecode/bytecode.

Solving the Mystery of ARM7TDMI Multiply Carry Flag (bmchtech.github.io)
The Gameboy Advance has a pretty neat CPU - the ARM7TDMI. And by neat, I mean a chaotic and sadistic bundle of questionable design decisions.

Solving the Mystery of ARM7TDMI Multiply Carry Flag (bmchtech.github.io)
The Gameboy Advance has a pretty neat CPU - the ARM7TDMI. This CPU is quite complicated - it allows the program counter to be used a general purpose register, implying it can be used as the output to any data processing instruction. That’s like allowing a drunk driver to change their tires while going 30 over the speed limit near a school. It’s a unique feature that can lead to very funny instructions.

A Lisp compiler to ARM written in Lisp (ulisp.com)
This is a simple experimental Lisp compiler, written in uLisp, that will compile a Lisp function into ARM machine code. My aim was to make the compiler simple enough so that its listing will fit on a single sheet of A4 paper.
