Conquest of the Crystal Palace: Matendouji - Weapon Select 3-Round Mode

It's not a very famous, but rather interesting game. It's also quite difficult, especially on the second "round", which is normally available after completing the first game round. But the hack allows you to choose second round from the start. In addition to this the new playable round was added. Also, the weapon-select mechanics was added and the sword hitboxes were fixed.
- After pressing "start" button in the main menu the "sound-test" and the "round-choose" menu appears. Use "left/right" buttons to choose BGM, "A" to play, "B" to stop. Press "down" and then "left/right" to change game round. Press "start" to begin game.
- In the 3rd game round the player's invincibility period after taking damage is reduced, and the HP of the enemies is 1.5 larger, than on the 2nd round;
- The standard game mechanics requires you to press "A" button while sitting to summon guardian dog, equip sword, magic or use Moon Mirror. In addition to this the hack allows you to press "select" button to quickly switch between sword and magic.
- There is a problem in original game with the sword hitboxes, which doesn't allow you to hit certain enemies (example is on screenshot #4 - the rightmost "fly" cannot be hit as long as it's flying on this height) - this was fixed.
- The great healing item now can heal the guardian dog, too.
- The magic mirror, given by the Moon Princess is no longer lost on GameOver;
- Logic of the 3rd boss was changed: you can no longer wait idly for it to appear and go away)
