Shadow of the Ninja: KAGE - WeaponSelect Both-player 5-in-1 Mode

The hack allows you to play this good old game on greater difficulties (if you are up to it), or on standard one - which is, in fact, can be challenging enough. It also adds the ability to "store" shurikens and bombs with "Select" button, so that you can use them later (for more tactical approach).
In addition to the standard 1-player and 2-player modes the hack presents the third playable mode - where you play for BOTH characters at the same time! This mode will require new tactics, giving an opportunity to play this old game like a new one)
- Just push "Start" on the title screen to start the game with normal 1x damage multiplier;
- Use "Left" or "Right" buttons to increase or decrease difficulty (2x, 4x, 8x damage multiplier or "instant-death" mode). Each press is followed with a special sound;
- During a game press "Select" button to store or re-equip your consumable projectile weapons (the feature also works in two-player coop game and on "both-mode");
- On "Both-mode" use the "start" button to switch between characters (remember that "pausing" won't work on "Both-mode"!), hold down "start" to simultaneously move both characters (up-down-left-right);
- There is a single change in 5-th level, which doesn't make it easier, but allows you to pass without damage on "Both-mode". For the same reason the room in 2-nd level, where "snake" attacks, is remodelled a little, too;
- HP-consumption of a Special Ninjutsu lightning-attack (which is used holding the B-button) is lesser now, allowing the use of two special attacks with max HP;
- In addition to this the player becomes invincible, when the Special attack's charge is at 50%. You can release the B-button to use only this "invincibility effect" (this will cost 1HP instead of 7).
