PlayStation 2 History Tweaker 2022-07-11

This is a Simple GUI to browse, edit amd save history files

whith the possibility of editing, erasing, cleaning, copying and pasting entries

Also, the program can simulate a game execution (modify the values as if the console ran the game once) (this feature is based on OPL OSDHistory.c)

Please report bugs, this tool is open source.

That's cool app. Could You elaborate more what are BitMask and ShiftAmount, what is their purpose? And how large this database can be?

For what I've seen in OPL code, the history file holds 21 entries (22 bytes x 21 entries = 462 bytes)

When the history gets full, OPL starts looking for the least used entry, then it exiles it into history.old, then rewrites the entry with the new data...

The bitmask and shift amount are changed when launch count reaches a specific number (use the feature to simulate the game run)

Could you make it for the PS2? That will avoid the hassle of copying the file to the PC...
