Submission #4067: Robert_Ordis's GBA Castlevania: Harmony of Dissonance "Simon, Hard, Boss Rush" in 07:51.27

This Bossrush mode is an addition which is playable after clear this game "Castlevania: Harmony of Dissonance" . Player defeats many many bosses (in "Hard" mode, number of bosses is 18)

You can play this as Simon Belmont if you input "Konami Code" (↑↑↓↓←→←→ＢＡ） while showing Konami's logo. If you clear "Hard" mode as Simon, you can see the special picture with ending music.

This run used the SRAM which has Hardmode Bossrush. To play Hardmode, you must clear "Easy" and "Normal" mode. The movie that generates SRAM of this run is here.

It is started from SRAM of this run.

In this run, Simon performs this glitch in the following way.

1.Attack by "Subweapon:Cross(ID:0x09)" and "Midair whipping(ID:0x02)".

2.Attack by "Land whipping(ID:0x03)" while two invulnerabilities are remained.

Total damage is here. 138 (by midair whipping) + 103*M (by the cross) + 138*n(by a glitch) M is the number of times of hit by cross. n is times of multiple hits.

1 is substituted for M normally, but in case of using "Powerful" method as stated below and enemy's hitbox is already enabled when Simon entered the room (like Living Armor), 2 is substituted for M.

In 2nd step, Simon uses 2 different hitbox.

The first case is that if the enemy has a little of HP like Dracula Wraith (1st).

In this case, Simon uses a behind hitbox to perform the glitch quickly.

However, since the hitbox moves from behind to front in 12th frames from starting whip attack, the multiple hitting time length in this case is only 11 frames.

So, enemy's damage that is caused by this "quickly" method is 138*11+138+103=1759 (no critical hits).

The second case is that if the enemy has a lot of HP like Living Armor. In this case, Simon uses a front hitbox to perform the glitch maximally. Max length of Simon's multiple hit is 20 frames (invulnerability of cross). If Simon doesn't draw any critical hit, max damage is 138*20+138+103=3001 or 138*20+138+103*2=3104. Although this "Powerful" method can inflict great damage upon the enemy, "Quickly" method can defeat the enemy 11 frames faster than it if enemy doesn't have a lot of HP.

But when you fight with Living Armor or Talos, you must be careful to avoid excessive multiple damage. Because death effect of them are started when them hitbox stopped reacting to attacks. And Legion Saint's shells doesn't take damage by this glitch because of them special invulnerability.

In Simon mode, going up/down the stair is different from Juste/Maxim. If you released left/right button while moving on the stair, the coordinates of Simon will be modified to next/behind the step. To go up/down the stair quickly, release the button on where Simon's position will be modified to next step. The speed of running method is 1.6 pixels/frames

Simon can't perform the multiple hitting glitch quickly continuously because he has no way to cancel his any

motions. So, in either case of using "quickly" or "powerful" method, drawing critical hit is very important.

In Simon's Bossrush, you have to do these action to consume the Random Number.

1.Jumping

2.Breaking candles

3.Appearing Magic Crystal after defeating enemies

3 consumes Random Number very fast. But it consume some frames too. Since of this, 1 and 2 is used for luck manipulation basically.

Critical hit detection depends on lower 2 bytes of Random Number (0x02000008:4 bytes). While performing multiple hit glitch after luck manipulation, Simon can draw 2～3 critical hits normally.

In this run, I used high-density critical hits area to the enemy whose HP is over 3001 or 1759 preferentially.

gochaism:for her(?) RNG Simulator.
gstick:for his precognition method for critical hits.

To make this movie, I used this lua script that shows status of enemies and player, hitbox and precognition for

critical hits(method by gocha and gstick). [dead link removed].

Watch Simon Belmont the great old vampire hunter !!

Simon Belmont Forever!!
