Setup for star icon invalid slot :
- make a new save1
- load progressed save and make 1 glitched slot
- use VOS and load save1 (see <https://youtu.be/nEOoSrMviHI>)
-> you will respawn on SOR cliff
- climb down and pick up a material (the closest is under a rock)
-> so now we have a undiscovered tab but the following should depend on 3 tab alignment, those instructions try every tab alignment to be sure it works
- open inv and go to item section
- press dpad left
- close, open inv and go to item section
- with the right joystick, press left
- close, open inv and go to item section
- with the right joystick, press left
-> you should have a star icon invalid slot
- go to system tab, try dpad left to make sure you have a invalid slots on star icon
- load progressed file

Now how to create a invalid slot with it (on any tab, col 5, raw 1;2;3) :
- go to the tab to the right of the target tab, col 5 and on the raw you want to get + 1 (for example if you want raw 2 you need to be on raw 3)
-  move left with the right joystick
- quick tap, dpad up
- quick tap, move right with the right joystick
- quick tap, dpad left (to get on the slot)

Then the you will follow the usual instructions to move the invalid slots to any column and use hpe with the usual 3 tab logic
