This is the primary BIOS, typically housed in a 128KB EPROM (Erasable Programmable Read-Only Memory). It is responsible for the heavy lifting: neo geo bios
The Neo Geo BIOS represents a bygone era of hardware design. Today, firmware is flashed via the internet and consoles run operating systems in the gigabytes. The Neo Geo BIOS, by contrast, was a tight, efficient, and permanent slice of code. It was the gatekeeper of the "160 Meg Shock" and the conductor of the arcade symphony.
