Hey, sorry to necro a thread.. but I was curious if you could share more details on how you came across the button combo? It was awesome for me to find out something I didn't know about a game I loved as a kid. After seeing your post on another site, I tried to find the source of the combo and finally found you lol. Then i looked into info for the original 3 x games to find if there was such a combo for the others as well. Seems x1 and x2 have these combos, and I'd like to try to find something similar for x3. Thanks in advance, and awesome work!
