An unused item in the game's code, the Bath Set, is an accessory that can be equipped. Equipping the item prior to entering the bath will cause the wearer to have an item display in front of them.

There is an unused rune in the game's code called the "Solitude Rune" which can only be obtained through the use of hacking or a cheat device. The rune will increase a weapon's attack power based on how many people are in your party: the fewer, the greater the increase. It was likely removed due to the extremely substantial boost to the attack stat that the rune can create.

McDohl's name has a bizarre glitch when transferring data from Suikoden to Suikoden II. In canon, the hero's name in the first game is Tir McDohl, however the game only transfers the capital letters of the name across, so naming him Tir will result in his name being TcDohl in Suikoden II. In order for his name to be McDohl in the second name, you would have to name him something with only a capital M in the first game. If you name him something in full capitals, it will all be transferred across, for example, naming him TIR will result in his name being TIRohl.

If Jowy is hacked into the party during the game, neither the "King" version, or "Best Friend" version will appear in the HQ anywhere. They can both be removed and added to the party with unique (and different) dialogue, despite these never normally being accessible through traditional means. "Best Friend" Jowy can also be awarded the statue that appears at the top of the castle for obtaining the most kills, even though he is never a part of the party's team after the events that lead to the castle being accessible.

There are many unique dialogue choices for the end of the game after defeating the Beast Rune. Some of these require special conditions to be met, such as having only a single character with you.

Jowy and Nanami can also be hacked into the party using code, which will reveal Jowy having glitched text, but Nanami will have understandable dialogue.

If the player decides to run away with Nanami during the events that develop around Tinto, the player can reveal an alternate ending in which the hero and Nanami will live quietly in the country.

Additionally, many characters have unique dialogue during this scene, including a script coded in for both Viktor and Flik, even though there's no way for you to put them in your party at this point in the game.
