create a rom hack to turn on level select on the title screen

• press up and down on title screen to select level
• changed some colors on the title screen, but also changed the game color in general (just for fun)
• infinite continue because it's a practice rom

automatically set the right power up when selecting a level

• level > 2 --> high jump
• level > 4 --> slash
• level > 9 --> high slash
• level > 10 --> low slash
• level > 13 --> berserker
