Hex tweak submission

[begrimed]

I figured this was a better place than completed stuff, but if someone else feels otherwise, go ahead and move it there if you want.

As the name of this topic implies, stick any hex tweaks you find in this topic instead of PMing them to me. Since I'm a bit slow at updating the site sometimes (hahaha, a bit?), posting them here for all to see right away will get them out there faster until they do appear on the hex page.

In the meantime, here's some that Sadi found and sent me the other day:

$241D2 - 06 00 33 A8 to 24 87 B1 C4      (Green Right)
$24231 - 06 00 63 A8 to 24 87 E2 C4      (Green Left)
$24290 - 06 00 93 A8 to 24 87 13 C5      (Green Down)
$242EF - 06 00 C3 A8 to 24 87 44 C5      (Green Up)
$24351 - 06 00 F3 A8 to 24 87 B1 C4      (Red Right)
$243B3 - 06 00 23 A9 to 24 87 E2 C4      (Red Left)
$24415 - 06 00 53 A9 to 24 87 13 C5      (Red Down)
$24477 - 06 00 83 A9 to 24 87 44 C5      (Red Up)
   Above changes make missile doors change to standard blue doors after being unlocked. They require an extra hit to open (as a standard blue door)

[Lunaria]

Even better would be if made a hex tweak map in the site in the same manner as a ROM and RAM map. :P

[snarfblam]

Wouldn't the wiki be the ideal place for these kinds of things?

[Quietus]

Logically, yes, but since a lot of the basic info is missing / not done, then I can't see people using it as it should be, and that may in turn mean that the hex tweaks are missed.  We'll then have a bajillion new topics asking about things.

[snarfblam]

Well, then putting this stuff in the wiki would be a good start. If the wiki's ever gonna get going, somebody's got to start it rolling. A forum is a poor substitute for this kind of stuff. A wiki is an ideal place for this information to gather to allow the documentation evolve in an organized, useful, manageable manner.

As you see, there are two address. First one used when loading the game with non-zero ammunition of certain type. Second one -- when collecting ammunition of certain type for the first time.

These ones were found by DC long ago and they are working (but still not in the tweaks):

**Initial load of HUD during game load**
-- This is needed so the top row is sent to RAM when you load a game.
Change this (load): 1AA3, [ BD CB 98 ] To -> [ BD 8B 98 ]
Change this (store): 1AA6, [ 9F 08 C6 7E ] To -> [ 9F C8 C5 7E ]
Change this (counter): 1AAC, [ E0 C0 00 ] To -> [ E0 00 01 ]

**In-game DMA transfer**
-- This is needed to transfer the extra row of the HUD to VRAM.
Change this (source address): 1CB4, [ A9 08 C6 ] To -> [ A9 C8 C5 ]
Change this (VRAM destination): 1CC1, [ A9 20 58 ] To -> [ A9 00 58 ]
Change this (number of bytes): 1CAD, [ A9 C0 00 ] To -> [ A9 00 01 ]

Note to existing tweak

824F5 - AD D0 0C to EA EA EA
Disables the pseudo screw attack, which happens if Samus does a spinning jump during a beam charge (found by Crashtour99).

This one is having very interesting side effect. You can't perform a pseudo screw attack with charged beam, but you can do this if no charging beam at all. It means, every spin jump will cause pseudo screw attack, but without yellow shining of Samus.

And since then...
82504
Change 8D 6E 0A to EA EA EA
Disables the Pseudo Screw Attack completly.

[begrimed]

137779 - 90 to 80 = no screen shake at all when escaping Ceres.

I can almost guarantee that 99% of people here will have no idea what those do JAM, as in Vanilla SM you have only 1 chance to perform the code, and by that time you should have more than what it gives you, so it's inherintly useless. Plus what's the chance of someone holding the few buttons it requires to activate?

To actually make the code useful for most players would be to have it always run, which presents the problem of making item collection up to that point entirely useless.

[Quietus]

For those into speedrunning the game, the code actually allows you to beat the world record speedruns, but it's not accepted due to it's game breaking nature.  You basically get to GT's room via the back door asap, using the Green Gate Glitch, and use the code.  It gives you enough equipment to then complete the game, as no more equipment is required.

[JAM]

I can almost guarantee that 99% of people here will have no idea what those do JAM, as in Vanilla SM you have only 1 chance to perform the code

Yeah, I think, I should explain it better.

by that time you should have more than what it gives you, so it's inherintly useless.

Like Quietus said. Also, if enter GT room with minimum amount of ammo and energy and then enter the code, you can jump over 100% or items (if collect all remaining items) and finish the game with maximum 325 Missiles, 65 Super Missiles, 65 Power Bombs, 2100 Energy, 700 Reserve Energy and 135%.

Excellent timing. Just so happens I'm currently working on making an awesome Torizo battle for my hack, and these hex changes will really help out in making that happen. Thanks for these!

On a funny note, I tried modifying his walking and turning speeds to half of the standard numbers, and now Torizo is an absolute speed demon because he closes in VERY quickly no matter where I am. :lol: Might have to slow him down a bit again because of that.

[uzqap]

I found an interesting side effect in one of the HEX edit

84F71 - 02 to 01
Allows Samus to fire beams while the ice beam SBA is in effect (found by Flamestar666).

if you eliminate X of the ice SBA [by letting them hit enemies], but not all four and shoot.

this shot will be multiple shots
[5(max beams)-4+X]

noticeable when shooting at enemies and
at high vertical speed those projectiles will be separated and can be seen

DSO pointed me in the right direction of these; I just noted them in more detail. Some values handling Samus' animation speeds. Will probably find more later.

8B298 - 0A 0A 0A 0A = Standing, not moving.
8B29D - 08 08 08 08 = Standing, not moving, low health.

8B2A3 - 0A 0A 0A 0A = Crouching, not moving.
8B2A8 - 08 08 08 08 = Crouching, not moving, low health.

8B384-8B38C = Spinjump animation speeds.
8B494-8B49B = Spinjump animation speeds (after walljumping + holding jump).

8B392-8B399 = Space jump animation speeds.
8B49E-8B4A5 = Space jump animation speeds (after walljumping + holding jump).

8B39F-8B3B6 = Screw attack animation speeds.
8B4A8-8B4BF = Screw attack animation speeds (after walljumping + holding jump).

8B326 - 03 04 04 04 04 = Normal jumping.

8B22D - 05 02 = Landing from jump, facing right.
8B231 - 05 02 = Landing from jump, facing left.

8B236 - 05 02 = Landing from spinning jump, facing right.
8B23B - 05 02 = Landing from spinning jump, facing left.

8B3ED - 02 02 02 = Turning right to left, aiming down (L).
8B3F2 - 02 02 02 = Turning left to right, aiming down (L).

8B433 - 02 02 02 = Turning right to left, aiming up (R).
8B438 - 02 02 02 = Turning left to right, aiming up (R).

8B33A - 02 = In the air, aiming straight up.
8B33E - 02 = In the air, aiming straight down.
8B342 - 02 = In the air, moving left or right (not spinning).
8B346 - 02 = In the air, aiming up (R), down (L), or firing a shot.
8B34A - 08 06 06 = Falling off of ledge or de-morphing in the air.

<DSO> $90/82F0 BF 10 B0 91 LDA $91B010,x[$91:B044] < breakpoint on this
<DSO> Whatever it loads into A is the pointer to the timer for next animation
<DSO> And then it loads that timer right after that, which will tell you where it is
<DSO> For any animation

And some more. A few of these are more like cheats than gameplay mechanic edits.

82474 - D0 to 80 = Enables space jump without having the item. Uses normal spinjump animation.

8F6BD, 8F71E, 80450 - D0 to 80 = Uses space jump spinning graphics for normal spinjumps.

8F6B8, 8F719, 8044B - D0 to 80 = Enables screw attack without having the item collected.

82471 - 89 00 20 = Check for which item enables space jumping, but not faster spinjump animation.

8191C - 89 00 20 to EA EA EA = Jumps gain some extra height if Samus is running, even without speed booster.

125BD - 80 00 10 to EA EA EA = Pressing any button will unpause the game; effectively disables equipment screen use.

840AB-840E6 = Stuff for 5-bomb spread. Checks Samus' equipment for bombs, if beam is being charged and beam charge timer.
840AB - AD to A9 = Disables use of the bomb spread.
840B3 - AD to A9 = Always use bomb spread in place of normal bombs.
840BB - AD to A9 = Disables bomb spread, and as well as morphing while beam charging.

8178C - 89 to A9 = Samus runs faster even if speed booster isn't collected or equipped. No sound/blue echoes until Samus has the item.

84669 - F0 to 80 = Alternate arm canon graphics never trigger when selecting missiles or super missiles.

8427B - 0A 14 = Speed that missiles can be fired. 0A = missiles. 14 = super missiles. Missiles can be changed to shoot faster or slower without any real problems. Super missiles can be changed to fire slower without issue, but to fire super missiles faster, you need to first apply Kejardon's super missile fix ASM so that more than one super missile can be shown on-screen at once.

84EF7-84F27 = The 4 rotating pieces of ice beam SBA no longer disappear after touching an enemy.

845FB - D0 to 80 = Ice beam SBA lasts forever.

845FB - D0 to F0 = Ice beam SBA disperses immediately after use.

8F464 - 28 00 = Distance from Samus that ice SBA starts dispersing from. 28 to 01 and it disperses from her body instead of from the ice circle.

And finally, here's a .txt file that lists animation frame speeds for almost every enemy and boss in the game. With this info you can alter how they behave to an extent. For some enemies the differences are as minor as how long to display a few colors. Other enemies have many animation sets and can practically be made into new ones. The document is still slightly unfinished, but most of what hasn't been added to it are a couple of bosses and some boring enemies that you wouldn't get much out of changing the animation speeds for anyway.

What item closes the door in Bomb Torizo's room. Bombs by default.

That gives me an idea for a nice little hijack piece of code SMILEuser :P.

ie. making the stay open doors more useful.

Not entirely a hex tweak, but could be useful information.

Addition to RAM map:

Correcting and addition to existing tweaks.

81E98 - 02 to ?? [air]
81E9C - 00 to ?? [water]
Adjusts how quickly you can repeatedly use space jump. 00 = more frequently, 02 = standard, 04 = less frequently, etc. (found by Black Falcon)

81E9A - 05 to ?? [air]
81E9E - 05 to ?? [water]
Adjusts how long Samus must fall before space jump no longer works. The value differences are pretty radical, though. 04 = barely have to fall before you can no longer jump, 05 = standard, 06 = seemingly no limit to how long you can fall and still use space jump again, etc. (found by Black Falcon)

All these values depending on falling speed. Since default terminal velocity is 05, you'll never fall faster. That's why values above 05 allows to use Space Jump even after falling in any amount of screens.

If terminal velocity [at 81110] is increased, you can set higher value here and give Samus more time to perform Space Jump. If values at 81E9A or 81E9E exceeds 81110, time will be unlimited again.

If gravity is decreased, you'll have more time to perform Space Jump with default values because you'll reach terminal velocity slower.


And maximum falling speed is measured in 1/256 pixels per frame in these 2 tweaks. Well, Samus' speed is a 32-bit value. Values here are compared with middle bytes in the middle.

So, in general, first pair of tweaks is minimum falling speed when Space Jump can be performed and last pair is maximum falling speed when it can be done. And values are actually 16-bit and should be tracked like this:

81E97 - 80 02 to ?? ?? [air]
81E9B - 80 00 to ?? ?? [water]

Minimum falling speed required to use space jump.
Decrease values to be able to start using space jump earlier.
Increase values to be able to start using space jump later.

Increase gravity to be able to start using space jump earlier, but have less time to perform space jump.
Decrease gravity to be able to start using space jump later, but have more time to perform space jump.

81E99 - 00 05 to ?? ?? [air]
81E9D - 00 05 to ?? ?? [water]

After reaching this falling speed space jump is unavailable.
Reduce values to have less time to use space jump.
Increase values to have more time to use space jump.

Values greater than terminal velocity [at 81110] like 05.01 and greater allowing to use space jump after falling from any height but not earlier than values at 81E97 and 81E9B.

Increase gravity to have less time to use space jump.
Decrease gravity to have more time to use space jump.

Increase terminal velocity at 81110 to be able to set values above 05.00 and have more time to use space jump, but not infinite.

D0 to 80
Prevents Samus from losing speed by turning left/right during a spinning jump. But more smootly, without entering "about to walljump" pose for a few frames.

Same effect.

B4 00 to ?? ??
Shinespark timer in frames. Higher values works, but "ready to super jump" sound will be clipped before flashing ends.

New one that only took me a few minutes to find.

$84/8972 (020972) = change 8D C2 09 to EA EA EA to make energy tanks not refill health when collected (still expands health capacity as normal).

Since you were kinda looking at that area, would it also be possible to actually just have it add the quantity it grants you?  e.g. If in your hack they grant 50, it'd just add 50, or in the original game it'd add 100, rather than refilling?
