RetroBoot 121 (hereafter RB-121) is designed to be a "thin abstraction layer." It does not seek to replace the operating system but rather to provide a standardized environment for loading kernels, diagnostic tools, or ROM images from non-standard storage media (such as SD cards or Flash memory) on hardware that originally relied on floppy disks or ROM cartridges.
The "121" in the name refers to its target boot time: 1.21 seconds from boot to menu (on supported hardware). While real-world figures hover closer to 3–4 seconds depending on the device, the promise remains—this is the fastest-loading emulation environment on the market.
