Please remove leading zeroes from the size value. Also applies to all other encounters in this file.

Not sure if this comment is necessary, but if you want to keep it, add spaces after the opening and before the closing.

If it's 0, remove it. Might be useful to set it to 16 though, as this memory easily gets corrupted on reboots.
