This glitch is intended to give you the max number of metals in the game in just one pause during gameplay. First you need to have a life tank and make sure its not completely full, recommended half full. Second you need to have less than 50 metals. Go to the the R&D development room and get a life charge for the life tank which costs 50 metals to obtain, the game will glitch out and your metal counter will disappear from screen. go to any level and go find a single metal anywhere on the level, the metal counter will increase insanely. Now press start to pause and bring up the player menu screen, your counter will read 9999999, the maximum number of metals possible in the game!

This move appeared in Megaman X2 as an ultimate move (like the Hadoken in Megaman X1). It's not powerful at all, but a fun easter egg.
