...The Selfie Project provides an educational platform for teaching undergraduate and graduate students the design and implementation of programming languages and runtime systems. The focus is on the construction of compilers, libraries, operating systems, and even virtual machine monitors. The common theme is to identify and resolve self-reference in systems code which is seen as the key challenge when teaching systems engineering, hence the name. Selfie is implemented in a single (!) file and kept minimal for simplicity. There is also a simple in-memory linker, a RISC-U disassembler, a garbage collector, L1 instruction and data caches, a profiler, and a debugger with replay.

This is a C compiler, assembler, linker and virtual machine for computing based on encrypted working and obfuscated compilation and execution. The idea is that the platform machine `works encrypted' for the user and unencrypted for the operator, running a machine code instruction set in user mode that is provably safe against computational attacks, for code that is generated by a compiler that has introduced random variations into the code at each recompilation so that the attacker has no statistical leverage from human programming biases.

Lilac is a tool suite, which contains an assembler and a disassembler for the JVM (Java Virtual Machine) bytecode. The assembler takes textual representations of Java classes, written in an assembler-like syntax, and converts them to binary Java class files, which can be loaded into JVM. The disassembler takes binary Java class files and creates out of them assembler files suitable for the assembler. In general (except for some very rare cases) Lilac tools allow a perfect round-trip, that is, if you disassemble a class file and then assemble it again, without making any changes, you'll get the original file.

Java Classfile assembler/disassembler and low-level interactive editor. Allows viewing and manipulation of Java class data both manually and via scripts. Load in a class file, make changes, and then save the result.

bMARS is a java implementation of Redcode virtual machine MARS - "Memory Array Redcode Simulator"

Flasm is an assembler/disassembler for Flash actionscript bytecode. Using flasm, script authors may learn how actionscript compiler and Flash Player virtual machine work, and tweak the compiled bytecode in SWF files for performance.

A open source java card virtual machine implementation. And also some part of the VM code can be used as part of kinds of tools such as javacard bytecode disassembler.
