The original release of the Super Game Boy runs about 4% faster than an original Game Boy. This is most noticeable in the audio playback, but it also means that the SGB is not allowed for use in speed-running, and is part of the reason why there is no link port available, since the speed difference would cause the communication to desync. The later Japan-only Super Game Boy 2 fixed this problem by installing a crystal oscillator running at the correct speed.
There have been mods floating around online showing how to replace the clock in the SGB1 with a crystal oscillator running at the original Game Boy's speed. However, the way these other mods are done actually breaks some cool features of the Super Game Boy where it's possible to speed up and slow down the gameplay using the Super Game Boy Commander controller from Hori.
This mod avoids those issues by properly applying the fixed clock speed into the I/O chip, the same way the SGB2 does. It is also much easier to install, because it doesn't require lifting any pins, and the solder points are much easier to attach to.
