Memory Editor [Vega]
This code will allow you to view and edit any section of Memory. In regards to editing Memory, only word writes can be done. Once the game loads past the Boot Strap screen, the Memory Editor will appear.
The top word field is the location in Memory that you are currently viewing. Starts at 0x80000000.
The word field below that is your temp field to edit in a value to navigate to Memory or write in to Memory. Starts as 0x80000000.
Once you have navigated to a new spot, the top field will auto update. View the button keymap below for instructions on how to fill out your controller values.
Button Keymap:
XXXX = Controller Address
RRRR = Button to increase digit in temp field
SSSS = Button to decrease digit in temp field
TTTT = Button to move left on temp field
UUUU = Button to move right on temp field
YYYY = Button to use value in temp field to navigate to new spot in Memory
ZZZZ = Button to use value in temp field to write to Memory.
For safety reasons, you must release all other buttons when using a button in the keymap.
The code makes use of the follow memory addresses:
0x800003B0 thru 0x800003BF
0x80000DD0 thru 0x80000E7A
Make sure no other codes in your GCT/Cheat-Manager are using those addresses!

This code will allow you to view and edit any section of Memory. In regards to editing Memory, only word writes can be done. Once the game loads past the Boot Strap screen, the Memory Editor will appear.
The top word field is the location in Memory that you are currently viewing. Starts at 0x80000000.
The word field below that is your temp field to edit in a value to navigate to Memory or write in to Memory. Starts as 0x80000000.
Once you have navigated to a new spot, the top field will auto update. View the button keymap below for instructions on how to fill out your controller values.
Button Keymap:
XXXX = Controller Address
RRRR = Button to increase digit in temp field
SSSS = Button to decrease digit in temp field
TTTT = Button to move left on temp field
UUUU = Button to move right on temp field
YYYY = Button to use value in temp field to navigate to new spot in Memory
ZZZZ = Button to use value in temp field to write to Memory.
For safety reasons, you must release all other buttons when using a button in the keymap.
The code makes use of the follow memory addresses:
0x800003B0 thru 0x800003BF
0x80000DD0 thru 0x80000E7A
Make sure no other codes in your GCT/Cheat-Manager are using those addresses!
