To understand the significance of NeoRAGEx 5.2a, one must first understand the landscape of emulation in the late 1990s and early 2000s. During this time, computing power was a fraction of what it is today, and emulating the complex hardware of the Neo Geo—specifically its large cartridge sizes and custom sound chips—was a daunting task. NeoRAGEx emerged as a revolutionary solution. It was lean, optimized, and capable of running demanding games on relatively modest hardware. It popularized features that are now standard, such as the ability to save states, apply graphical filters, and use cheat codes.
