Pretty close to the original binary except for the first loop, which generates differently. (TODO comment added) There are also some questionable double address calculations, which hopfully clear up when the loop is fixed as well.
Also added enums `inv_body_loc` and `inv_xy_slot` to clean up a lot of magic numbers.
Now binary exact except for the usual `xor; inc` vs `push 1; pop` switch.
Updated the type of `_iIdentified` to `BOOL` as well (since every write to it actually is 0 or 1).
This is now as close as it gets without switching to enum types/parameters everywhere, so the compiler can optimize all accesses/checks accordingly. This is especially noticeable in the way the code for the switch is generated (line 775). In the original binary you can see it does weird stuff if c is not one of the classes' enum value (probably due to optimization since the switch should be exhaustive).
I've tried switching the type of c to _ui_classes, also removing the UI_NUM_CLASSES value to see if that'd be enough to let it generate the optimized code, but nope, seems like we need to change it all at once. Currently, _pClass is a char, but an enum value would fit there as well, size-wise (alignment).
That's also why I'm guessing there had to be another enum for player classes, without the UI_NUM_CLASSES value...
* Rewrote GetManaAmount to result in the same decompiled code as the original function.
Fixed the type of `PlayerStruct->pClass`. Thank you @galaxyhaxz for all the help getting into it :)
* Renamed everything back to their original names
