Editing Zelda 3 Blade Beam
So I've been doing some mods and edits to my ALTTP and I've always wanted to edit the blade beam to be the things the Wizards shoot out. That or remove the function all together. Though replacing that swirl with what the wizards shoot would be great. Thanks for the help.

Disabling is rather easy:
pc 03/9c7b: b0 -> 80
giving it another appearance: you can try changing the tile with zcompress, but you need to know some asm to disabling mirroring and flipping.

I was afraid of this but I was going to have to cross this bridge eventually. How would I even apply this code to the rom? I have the program to add ASM patches to a rom but have never made a ASM patch myself. Can that be converted into HEX? Or be presented in the form of a patch so I can look at it and copy the precise coding?

Re: Editing Zelda 3 Blade Beam
Do you really want to go that road then? Without any asm skills you won't get much far to adjust the rom to specific needs. But people already made some nice hacks only using HM. Much luck.
You need to open the rom in a hex editor. I use ultraedit, but there are also free ones available (Google, I think hex editor MX can be recommended).
Then go to the address I told you:
Line 00039c70, byte b, change b0 to 80 just as you see in the pic. You could make then an ips out of it.

Oh I hex edit things all day, it's ASM patches I know nothing about. Well rather, I can apply a pre made ASM patch but do not know how to make one myself.
Edit: I can open pre made ASM patches with a notepad and edit that, and I've tried that, copying and pasting a code from here, but it wouldn't work.

Well that's the paradox then. If you hex edit all day, than you obviously should be able to hex edit this one byte. In a hex editor go to address 039C7B and change the byte B0 to 80. No ASM here, no patches, no applying ASM. Making a patch out of this is useless, since the patch would change only this one byte. And you constantly speak of ASM, yet there is no ASM involved in this one byte change.KonaXKona wrote: How would I even apply this code to the rom?
And where would you paste the code to. The ASM code can not be "pasted" into the Rom. The ASM is assembled into the Rom using an assembler, such as xkas, where the command lines are translated into the machine code: ie bytes. Thus every ASM will essentially result in a number of bytes for the SNES CPU to read.KonaXKona wrote: Edit: I can open pre made ASM patches with a notepad and edit that, and I've tried that, copying and pasting a code from here, but it wouldn't work.
On the other hand, you can copy paste series of bytes into the rom, as this code already is assembled, and is thus regarded as hex, rather than asm. In the upper case only the byte 80 gets copy pasted, if (for some unknown reason) you don't wish to type it out manually at the given address.

From the moment he put it up as a hex I had already edited it into my rom, the thing is this rom is pre patched with the IPS Zelda remaster thing I got from Romhacks.net so sometimes converting a ASM address to a hex doesn't work since there may already be coding in values in that spaces provided. Anyway, thanks alot for the code to Stop the blade beam. I wouldn't mind a code or two for the first question, how to turn it into the wizard projectile, but this is good too~

Re: Editing Zelda 3 Blade Beam
I think nobody ever tinkered on that projectile. The asm math for it must be complex and immense (circular and forthgoing).
I can only advise to search this tile in zcompress. Then you know how many tiles are there for this beam, and if it is possible to mirror/flip it to the wizrobes beam look. ~If~ it is possible (number of tiles etc.) you need to nop out much of the native circulating code, and mirror/flip it in dependence of the direction you stand.
But honestly, this is way too much work for almost zero gain. I'd rather think about another nice circling graphic/effect.

Re: Editing Zelda 3 Blade Beam
Good to know.From the moment he put it up as a hex I had already edited it into my rom.
Yes, however this location should be the same in all ALTTP roms/hacks.the thing is this rom is pre patched with the IPS Zelda remaster thing I got from Romhacks.net so sometimes converting a ASM address to a hex doesn't work since there may already be coding in values in that spaces provided
Basically to achieve that, you don't turn it directly, you edit the gfx for the projectile, to still be swords projectile. However now it will look like Agahnims magic projectile due to gfx edit.how to turn it into the wizard projectile
But like said, sword's projectile is most likely using only a quarter of the beam, which then gets mirrored to form a circle. If the game uses only quarter, than not even ASM will help, as you will have gfx space shortage. Best is to draw another circular beam, like Agahnims blue circle beam.

I had already suspected it was a quarter of a circle that was just flipped to make the blade beam projectile and I think I can locate it in the sprite sheet, what I'm looking to do is replace the projectile with:
But so far removing the blade beam funtion works also, looks nice, so on.
I Have another burning question, I found this somewhere and never took it down but I remember there was a method to make gannon able to be damaged with the Lvl2 sword or the normal blue master sword? Do you guys know of how to achieve that?

Re: Editing Zelda 3 Blade Beam
Basically it is easy:
06/b8f9: 00 -> 01 (makes Ganon vulnerable to L1 attack class)
06/b901: 00 -> 02 (makes Ganon vulnerable to L2 attack class)
but it is bug affective,
- if you enable l1 sword you can also hit him with sword beam/cane byrna and so on. I'd not recommend to make him vulnerable with l1 sword (you need 95 hits to get his life energy down to stage 2 anyways)
both enables have the problem that antifairies and peg switches can be destroyed now too.

Re: Editing Zelda 3 Blade Beam
It's pseudocode, so people know what to do.
If they have some minimal skills at least that is.
For example, know how to convert addresses, pc to snes lowrom, expanding a Rom, give offsets make a smicolon before clamps.
Here's the converted asm that you can use

Re: Editing Zelda 3 Blade Beam
Obviously it doesn't, since the XX,YY,ZZ need to be filled with the SNES/PC address of your choosing, while the assembled bytes are not even NOPed with the ; simbol. Thus the code is not "official" like in the bottom green frame. But it is easy convertable to its official state to be applied with Xkas.So this stuff is a ASM code right? How would I apply this, I tried copying it into a .asm and saving it then trying to patch my rom but that doesn't work.
What you need to do is first expand the rom from 1MB to 2MB, by adding 100000 bytes in hex with value 00 to the end of the rom, or use Lunar Expand. So again even applying the correct ASM will then probably not work in emus, since they usually require an even file size, ie 2MB in this case.
Then do this hex edit:
at 36DC0: change
BF F1 B8 0D
to
22 00 80 26
This is a jump to 130000 for instance, since 00 80 26 reversed is 268000= snes address= 130000 hex address (using snestuff for calculation). You can choose any free location.
if/when the rom is expanded to 200000, go to
130000, and write new code:
Conn was kind enough to actually also assemble it, so no need for xkas:
your code is this (this is what you indeed copy paste at 130000 using a hex editor):
BF F1 B8 0D E0 08 F0 05 E0 10 F0 01 6B 48 AD 20 0E C9 D6 F0 04 68 A9 00 6B 68 6B
Of course running the upper code (in the green frame) through XKAS will do the same. Note, in this case you need to first copy paste the code into the TXT/ASM file (for instance) pegswitch.asm and then run Xkas with this file using command line order. This is why I then always do the hex compare, so the upper hex info can be extracted to be able to quickly insert the code into any rom with just a hex editor (since Xkas is DOS based). But not neccessary in this case, since the ASM also has the bytes written aside the commands.

Re: Editing Zelda 3 Blade Beam
I took my time and applied everything and it all seems to work fine.
Info: I think the ISP patch expanded the rom because when using the program it told me the rom was already the right size, I applied the patch no problem and tested my attacks against Gannon and the peg switches~ So all of that works out.
Thank both of you for the break downs. I'm going to keep an eye on this thread still incase anyone cooks up a asm script or something to stop the spin of the blade beam and replace it with the projectile above, the slash things the wizards shoot. As much as I'm satisfied the idea of blade beams being more akin to A Link Between worlds would be AWESOME.

Re: Editing Zelda 3 Blade Beam
Conn: what about taking the approach seen in your Mothula fix, where you modify a monster's entry in the 7F/6000 structure at start-up? that should be smaller and simpler and risk less side effects, unless Ganon mucks with this RAM data in real-time.

You are speaking about the native bug fix, right?
Guess you are right, but... as said I am retired (just waiting for the conker 1.2.3 playtest), so I do not move another finger on patches that actually work (this approach surely is better and less risky but the current patch also has been tested bugfree.mothula_l4.ips (by Conn)
This patch fixes that the boss Mothula is immune against the Golden Sword and the spin attack from the Tempered Sword.

Well, the dw means that a word (2 bytes) are written from the asm.

If you look into my asm you find
- Code:

db $02 ; Ganon vulnerable to L2 sword
I do not know which asm you got this from, neither the address these two words shall be written to, so I can't help further.
Thanks But I am not irreplaceable. Euclid is a professional and he's also checking the forums daily (however he mostly checks the admin forums only I think). If something burns, a pm to him surely will help I guess.Same here, such people with ASM skills are rare, since this is somewhat specific and complex.

I got that little line from Orochimaru's Zelda 3 hacking compendium, it's the special sprite routine for the sparks that come out for the lvl2-4 swords. I was thinking posting that would help you guys find where that is located.
I know in Parallel worlds the sparks are disabled, I could remove them from the sprite sheet if I knew where they were.
