In the EXTRA07 folder, there are three demo files and the original title.demo file. The counter.demo is one-hit-kill mode where every attack is the counter. The water.demo file always gives you the level 2 beam, and hard.demo is one-hit-kill where you immediately cum if you're touched. To use any one of those, rename the file to title.demo and overwrite the file in the main game folder. The title screen will slightly change to denote the mode you chose. The bchara file in EXTRA07 is the unused enemy characters like the nurse, P.E. teacher, fighter, soccer player, and pink girl, but the sister was used. The update is supposed to be the final version of all the regular enemies since people complained about random glitches.
