 ## Play2
 
-In some particular instances, IDO requires the function argument `play` to be cast to a second variable of the same type to match. In these particular instances, the function argument should be renamed to `play2` and than this `play2` just assigned to a stack variable called `play`. This cast should occur before the actor `THIS` cast is made. For example in `z_en_firefly.c`

 ```
 
-In other places the cast is actually not explictly needed, but a stack `pad` variable is still needed. For this there should just be a stack variable called `pad` of type `s32` before the actor `THIS` cast. For example in `z_bg_goron_oyu`
