Do you have the latest Temporal Flux? That sounds like a bug that was fixed in 3.04.

Assuming that's the case, you can fix it pretty easily.

1) In Hi-Tech, open up *Life and *Lightning2. Note the animation index under the Graphics Header.
2) From the File menu, select Export. Choose Hi-Tech and Player Tech Animation.
3) Export the animation indexes you noted to individual files.
4) Under Window -> Strings, select Tech Descriptions. The last few will be corrupted. The last three are Single Tech, Dual Tech, and Triple Tech.
5) Save your ROM.
6) Import the files you exported earlier. This may not be necessary, but we don't want to corrupt your animations in the process.
7) Save your ROM again.

While you're at it, you should check any other string groups not marked (FL) for signs of corruption. It will always be in the last few of a group that hasn't been edited.

Let me know if you have any problems with this.

Also, you can swap your animations by changing the graphics header animation index, and the import/export feature can create duplicates or similar techs.

Seems like any time you try hacking a new game, there is a heck of a learning curve! :)

Thanks for the tips--I'll try this tonight!

Hey Mauron, thanks to you I got things working without a hitch.

I had a question about how to toggle single techs as usable or not usable from the menu, but I found a super helpful post from you on Chrono Compendium that answered it for me.

Thanks again!


Glad it's working.

I'll add the usable in menu toggle to the next version of Hi-Tech. I realized there was a fairly easy way to handle it just now.

Hi-Tech Beta 24!

- Fixed a save issue corrupting animations.
Mauron wuz here.

- Fixed bug with updating enemy effect headers.
- Added option to change which single techs are usable in the menu.

I'm working on investigating the layer 3 effects, such as *Lightning's bolt, or *Luminaire's green orb, to see what editing can be done with those. There will some kind of functionality in the next version.
Mauron wuz here.


Well that would explain why the mist dissapears on Mt Woe when you cast a spell.


Hi-Tech Beta 27!

- Added list of battle sounds (Thanks to xcalibur)
- Added list of Layer 3 packets
- Added editing of Layer 3 packets
- Added list of Layer 3 subpackets
- Added display of Layer 3 palettes.
- Updated Graphics Header.
- Simplified some loading code.
- Fixed issue with move up/move down commands

Assuming no bugs pop up, this will also be a stable release.

And a bug pops up.

Hi-Tech Beta 29!

Important: If you have changed animations in a prior version, save an animation in that group  (player attacks, player techs, items, enemy attacks, or enemy techs) again.

- Updated Enemy Tech and Super Command Descriptions

I'll probably have a few more improvements soon. I've almost decoded a couple new animation commands, but wanted to get this out first.

Quick patch from beta 28. The above notice still applies.

- Fixed a remaining issue with miss animations.
- Fixed an issue with detecting unfixed enemy attack animations.
- Tech animation command 0x69 decoded as set object palette.

So I was trying to modify Mune's X Strike because the current version of it is quite buggy and breaks the game when used on certain maps, however the editor doesn't seem to be saving my changes. What should I do to make it work properly?


Just to make sure, are you clicking Save Animation (or Save Control Header/Graphics Header/Effect Header), followed by File -> Save in the main Temporal Flux window?

There's probably a better way to label those buttons.

Edit: Hi-Tech Beta 30!

- Fixed bug with some animation commands being loaded incorrectly.
Mauron wuz here.



I'm having trouble finding a version that doesn't have problems with updating tech reqs. Earlier versions will save changes, but it's buggy and often the incorrect values are loaded and the game file will become corrupt. More recent versions seem to just prevent saving changes (it will appear to save, but it won't.)

Is this a known issue, or do you have any recommendations for getting around it?

One other thing I wanted to ask about is if there was any way with this tool to change the names for the ages displayed on the Epoch's Hud when you travel through time? It doesn't seem to be drawn from the string values located in "ages" or "years".



New, quick question - are there any existing maps (not locations) in the game that are unused that can be modified or built on?


Oh, sorry I missed this!

I'll double check the saving of tech requirements.

I haven't worked with the Epoch's HUD data much.

There probably are some unused maps, but I'm not sure which ones of the top of my head. You can also cheat the way they did and use one map for multiple locations, like the villages.

Edit: I found a couple issues with the tech requirement saving. One's fixed, the other will be addressed shortly. I'll have a new version out soon.

Hi-Tech Beta 31!

- Animation Command 5E decoded as hide caster or target variant
- Animation Command 5D decoded a draw caster or target variant
- Fully decoded Circular Sprite Movement
- Animation commands C4 and C5 decoded as vertical sprite movement.

- Animation Command A2 decoded as Move forward until collision
- Fully decoded Move Forward.
- Fixed bug with changing set angle variants
- Merged draw and remove copy commands in editor.
- Fixed saving of Tech requirements.
Mauron wuz here.


Is it possible to have a condition for learning the last tech in the list, like say killing Magus at the cape?


Nothing like that exists, but it might be doable as a hack, similar to the magic requirement.

Hey Mauron,

I was wondering if it's possible to tweak the animation objects without moving huge chunks of code.

This is my Ayla's Charm changes that makes it stop one enemy and remove the last Play Animation and Move to effect animation objects:

    db 80     // Base

As you can see, the animation objects change is quite significant and makes it much less portable. In fact, I had to write a script to compare all modified bytes, dump and format them into ASM.

Is it possible at all within the game to make this more portable? I still need to do the same for Twin Charm, making this doubly uglier.

Thank you!


Depending on your exact changes, most of those might be unnecessary. Chrono Trigger's default code only allows player tech animations to be loaded from bank $CE, and some objects are shared between multiple techs. Player Tech animation pointers are at 0x0D5EF0, with Cyclone at index 1. The data starts with the following format:

Hit object flags (2 bytes) Miss object flags (2 bytes) Object pointers (2 bytes each). The data starting at each object pointer is what's displayed in Hi-Tech.

Depending on what your new Charm and Twin Charm do, you may be able to work within the limitations of the original code.

Just those two commands removed.
According to Hi-Tech, 0x0E2D7C (02 03) and 0x0E2D7E (98 00 09).

I believe it's safe to leave the Move to command in without the Play Animation command, but I haven't tested yet.
I am fairly sure other animations don't use this object. I even checked Twin Charm and it uses different effect objects.

Would it be safe to just dw $0E2D7C to 0?


Definitely no on the that change, but there is a simpler change to remove two commands. db $35, 0 at $0E2D7C. Actually, db $71 at $0E2D77 might work better (Drawing Status: Show Effect to Drawing Status: Hide Effect). 00 works as an object terminator, so any commands beyond it would be ignored.
