Battle Summary Box Flashing Animation

This is unused code for WEST_FeLvUP (Special_LevelUpEvolve in the unofficial pret disassembly project) in the source code of Pokémon Ruby and Sapphire to flash the current Pokémon in battle's summary and experience bar, and play sound effect SE_W025,0 (SE_M_MEGA_KICK, 0 in pret).

(The unused parts are commented out using the /* and */ tags)

WEST_FeLvUP:
	SEPLAY_PAN	SE_EXPMAX,0
	ADD_TASK	LvUpGaugePaletteSet,PRI2,0
	WAIT		0
	ADD_TASK	LvUpEffColorFade,PRI5,2, 0,0
/*	WAIT_FLAG
	SEPLAY_PAN	SE_W025,0
	ADD_TASK	LvUpEffColorFade,PRI5,2, 1,5
	ADD_TASK	LvUpEffTask,PRI5,0
*/	WAIT_FLAG
	ADD_TASK	LvUpGaugePaletteRecover,PRI2,0
	SEQEND

Note a simulation of the animation was ported to the final versions of Pokémon Emerald by Flametix using pret, requiring a one frame delay using delay 1, however this adaption was written by Flametix and isn't the original.

Since the viral video by BlueBoyPhin there has also been speculation in the comments that this code was intended to indicate that an evolution is going to occur, because both Flametix and BlueBoyPhin's video played the animation before a Caterpie reached Level 7 (Caterpie evolves into Metapod at this level). However, there doesn't seem to be any evidence that this was its intended purpose. This commented out code was also introduced in the source code of Pokémon Ruby, not Pokémon Emerald.
