| Castlevania Chronicles
| Stack Buffer Overflow via unchecked string length
| The player name has a limit of 8 character strings to create a save-slot (Both original or arranged modes of the game). Since the string length/size is not checked, one can use a very large string to overwrite several stack registers including the '''''$ra(return address)''''' to eventually jump to unsigned code in the savegame.

| Brunswick Circuit Pro Bowling 1 & 2
| Stack Buffer Overflow via unchecked Custom Bowler Name length
| Brunswick Circuit Pro Bowling 1 & 2 offers players to create their own bowlers in terms of physical appearances and names. The bowlers' name is limited up to 15 characters long. When the player wants to create name, it's copied to the stack, however the string length isn't checked. With a very large string, one can overwrite the stack and take control of the return address'''($ra)''' to eventually jump to unsigned code in the savegame.

| Tony Hawk Pro Skater 2
| Stack Buffer Overflow via unchecked Custom Skater name
| The player has the chance to create their own skater(physical appearance, skateboard, names, etc.). The skater name is copied to the stack, however the string length isn't checked. With a large skater name, one can overwrite the stack and control the return address'''($ra)''' to eventually jump to unsigned code in the savegame. One can trigger this overflow by selecting "Career Mode" and then selecting the "Create a new career" option.

= Not exploitable game savedata vulnerabilities =

These are games that developers have fuzzed/researched trying to find bugs. Any useless crashes or games that do not crash at all go here. This is to inform researchers which games have already been studied.

* Family Feud -- Using a large string for the family name does not seem to crash the game. In conclusion, the family name is not exploitable. (Researched by [[User:ChampionLeake|ChampionLeake]])
