This document discusses RetroObjects, a framework and collection of emulators written in Smalltalk. It aims to allow emulating retro game consoles like the Commodore 64 and Nintendo Entertainment System in an object-oriented way. The framework provides abstractions for common hardware components like CPUs, video chips, and memory. It separates the emulator into a system model and objects for user input/output. This allows developers to focus on accurately modeling the target system architecture rather than low-level programming.
