You could make the sleep turns counter double up as a freeze turns counter while keeping the freeze status bit to differentiate between when the mon is asleep or when it's frozen.

Actually it'd be easier if you used a different address to keep the freeze turns counter so that you don't have to worry about modifying how other stuff checks for the sleep status. Not a big deal but should be a little easier even though it takes up an extra byte (you can always pick up an unused one like the stats to double / halve addresses that are unused).

Basically initialize a freeze counter at https://github.com/pret/pokered/blob/ma … .asm#L7457 to whatever value you want, and make sure it's decremented on every turn like the sleep counter is (https://github.com/pret/pokered/blob/ma … .asm#L3396). When the counter hits 0, defrost the pokemon as if it had taken a fire attack (https://github.com/pret/pokered/blob/ma … .asm#L7526)
