The decision to move to a 64-bit exclusive architecture is common in modern software development, driven by a few key factors. 64-bit applications can address more than 4GB of RAM, a necessity for emulating more complex systems like the PlayStation 2, GameCube, and Wii. Furthermore, many modern standalone emulators (like PCSX2, RPCS3, and Dolphin) are themselves developed exclusively as 64-bit applications. A 64-bit only RetroBat ensures better integration and performance with these tools.

Older 32-bit PCs often feature integrated Intel HD graphics or old Nvidia/AMD cards.

Building a DIY arcade cabinet often involves using cheap, recycled office PCs. Because arcade games from the 70s, 80s, and 90s do not require heavy 64-bit computing power, a 32-bit RetroBat setup is the most efficient software choice for these projects. 3. Maximum Compatibility for Classic Systems
