I doubled checked, xtatu did one version of x-ray, and Hiei-YYH did another version of X-Ray. They are the only 2 hackers I've seen do it for the game, but I'm not sure who did what. If I had a guess at a glance, it looks like both of xtatu's versions are triggered by hitting an enemy and then they give full X-ray. Hiei-YYH's version likely uses the read operation for the x-ray value so it would constantly refill it to full every second rather than being triggered by hitting an enemy or other things. But I'm still not sure, I've never heard of Anxify before, so I'm kind of guessing even though most codes I ever see came from CMP/games24blog/bbs.duowanwhateverchinesesite/playgame.lebonforum.com or maybe a few other obscure places.
I've changed the credits. Thanks for the heads up.
