There should be a checksum on the RHDN page though. Does it match up with that?

I just checked it, and it does not.  The filename is exact, too.  Someone must have messed with this one, or just labeled it wrong.   :bah: :lame:

I just checked the source of my download link.  It was jce3000gt.com.   :laugh:   I'm intensely curious what's in that chest now, in the unmodified ROM.  Going to play for 3 minutes and find out.  :)

EDIT: Yup!  The RuneAxe was in that chest!  Someone's been messing in my ROM.   :finger:

Is that a joke... or did that actually happen...? If so I had no idea there were so many bad dumps of FFIV out there. There's only supposed to be 300 GP in the chest.

It definitely happened.  I'm sure JCE was in the ROM at some point and just didn't realize that he had edited that version.  Funny coincidence that it ended up giving me Thor's Hammer after applying a hack patch.

I'm uploading my streamed videos directly to YouTube now, as they retain much better quality than when you archive them from Twitch.  I'll start streaming again in a few minutes, while I wait.  :)

Looking forward to it, From what I've seen of your video thus far it seems it will be an enjoyable watch.

Okay, Cid's Tackle is ready to go!
Couple of things to note:
  • The command is still called "Peep." I figured Pinkpuff should get to rename it to whatever she feels is appropriate
  • The spell I replaced was "Something happens to Adult Rydia," A.K.A. "y    ."
  • I made the command unperformable when critical, and thus had to make it so Kick can be executed when floating
  • The attached patch should be applied to an Unheadered ROM

For those of you interested in what's going on under the hood...
Code: [Select]

Just for fun...
I was playing around with some of those subroutines that I don't really know what they do. When you EA out the one at $02/FFC4, this is the result:

Wow, that looked fantastic! (Aside from the running in circles for ever) I have to wonder why FFIV kept it so basic. That idea has so much potential! Granted it wasn't until FFVI where Square really started experimenting with battle animations and all of that.

If you watch that video closely, Cid also runs backwards.
That doesn't happen in the actual animation.

The patch actually can be applied to any ROM (as long as you don't plan on running the "Adult Rydia Returns" battle, of course), if you wanna see the real command in action.

I can't wait to try it out! Thank you  so, so much for doing this for me, Chillyfeez!

And just in case it got lost in the discussion, was the damage display the only obstacle to having Lancet deal half of Kain's missing HP? Or was space an issue as well?

In Lancet's case it would turn out to be space. A simplified routine of giving Kain Drain and dividing his attack by 2 and jumping to the Fight routine wasn't so bad but adding a failure message took up a fair amount of remaining space.

The way that hypothetical would be drawn up is tricky

It would require basically writing the Remedy/Absorb routine and then having that deal damage at the end of it. Quite a few bytes really.

Oh ok no problem as it is, just wanted to check ^_^

Thank you both for this. The plain fighters should be considerably more interesting in the next version.

Hey, Pinkpuff, Am I correct in assuming because you haven't said anything else that the tackle command is working as planned?

... I have to wonder why FFIV kept it so basic. That idea has so much potential! Granted it wasn't until FFVI where Square really started experimenting with battle animations and all of that.
My guess would be that the pretty much just ran out of room. Vanilla FFIV only has about four lines of empty space in the 02 block, and that seems to be where every single bit of visual assembly is for battle (as well as some other situations). Command visuals are actually pretty simple - it's just making adjustments to x-position, y-position and pose sprite - but it can take quite a bit of coding space to do anything interesting, as I learned firsthand with this tackle command. If I had to guess, I'd say that's exactly why they nixed whatever plans they had for Cid's "crash" command.
