| Offset | Size | Content | |--------|------|---------| | 0x00 | 2 bytes | Block size in words (24-bit C31 words) | | 0x02 | 2 bytes | Destination address (e.g., 0x809800 ) | | 0x04 | N×4 bytes? Wait – careful | C31 memory is 24-bit, but EPROM is byte-wide. Bootloader rebuilds 24-bit words from 3 bytes. |

The BootROM computes a cryptographic hash (typically SHA-256 or SHA-512) of the entire c31bootbin binary.

The C31 Bootbin performs several key functions:

Regularly updated by the community to handle newer game updates. :

Thus, is a specialized, low-level boot binary tailored for a specific hardware platform or firmware branch. The "verified" status attached to it indicates that this binary has passed a set of cryptographic and integrity checks.

The "c31bootbin" is the foundational code that tells a machine how to wake up. To have it

In this case, the device freezes to prevent unsigned code from running, but the serial console does not print "failed" due to security through obscurity.
