It is recommended to add a bubble in the function area to explain how to use the selected function

If you don't look up other users' experiences on the web, you don't know how it works
These include Execute every and VBLANK Check and DEADBEEF

Well also in the original tool it was in that way but I think that we can add some information.

Execute every it is used to execute the trainer code at every tick (as I can remember), vblank check to execute it if there is a cleaning of the memory, deadbeef is for debugging purpose to fill the rest of the rom with a placeholder value.

Why would My use of DEADBEEF result in my cheating code Malfunctions and causes serious game problems

[Mte90]

Deadbeef is used for debugging, just adds to the ending of the rom in binary used a fake filler value, it is used to see if the rom has space to inject the trainer.
