GameShark (Pro) Probable Release Date

[Iconoclast]

I checked the binary of both the GameShark Pro V2.0 (Unl).z64 and GameShark Pro V3.3 (Unl) [!].z64 files and found some information hinting at their production/maybe release dates and their developing companies, which seem also to be unknown.

If I may post a few binary sections (copied from Notepad, not DOS), assuming none of you take it as linking to/uploading ROM files....

GameShark Pro V3.3:

Notice that these are all games published no later than 1998...so, here comes the 2.0 version, which actually has a year in the binary:
