There are tools that can quickly create colliding byte-sequences with the target hash code (see hashcat, and johntheripper). Many ROM hacks have a bad checksum, this does not necessarily mean you had the wrong ROM or patched it wrong. so recently, I decided I would try out an earthbound Romack that Romack being the 'earthbound enhanced' rom. Algorithms once believed to be secure, like MD5, have been long cracked. While choosing a hashing algorithm, we must decide how far we need to go to ensure the needed protection. Mario (J).smc is bad and has been part of the SMDB for a very long time, and seems to only exist in Game Series Collections. Main System: TrueNAS-13.0-U5.1, Supermicro X10SRH-cF with E5 1650-v4 CPU, 96 GB ECC RAM, 8x 4TB WD Red in RAIDZ2 + 8x 4TB WD Red in RAIDZ2 as local backup pool in Norco RPC-4224 chassis. If the application uses an application-layer protocol of our own design, it’s not difficult to add plain CRC, a CRC-protected data-compression, or even a cryptographic hashing code. My issue was resolved by reseating the drive and data cable. If reseating the CMOS does not fix the issue, it can be that the battery is dead. Ensure that the positive side of the battery faces up. Wait for a few minutes before inserting the battery into the socket. The battery should now pop out of the socket. One very good example of CRC protection at the application layer is the HTTP compression algorithm (defined in RFC 7231). ago bad checksum is a sign of BAD DUMP, BAD ROM or hackrom usage that the original developer did NOT fix the internal calculation. To remove the CMOS battery, press the lock located on the side of the CMOS battery socket. ![]() The more robust the detection, the more overhead and higher the latency and computing power. ![]() Furthermore, to achieve higher protection, we can use even stronger hashing algorithms, like SHA-256 (the same that is used by some known crypto-currencies). We can use the relatively fast and reliable Cyclic Redundancy Check – CRC32 algorithms (used in ZIP files, for instance). In this case, we can add more robust error detection in the application layer messages. Of course, there are applications in which we might not want to let the slightest chance of error not being detected.
