Do you want us to break it?

as a tekken player i know you lot over here are a pretty technical bunch. you don't really bother about storylines and shit.

Anyways,with the help of noman(T4 EU champ) , I've managed to write a small program that takes a tekken 4 replay save and decode the moves made by both players and shows them to you on a frame by frame breakdown.
it also lets you edit the data anyway you wish
www.claka.pwp.blueyonder.co.uk\bobjf.avi
you can if you wish build your own fight from the ground up. test or recreate any set/combo/punishment you want, and yes you could make combo movies with it.
I wondered how much interest there would be for it in the VF community.

 

link did not work

 

wow, how the $%$&@ does it work? That'd be GREAT. I'd be interested.

It'd be more useful for a game like VF2 where there are combos well beyond the abilities of humans. In VF4 any combo that IS possible looks like it's been done, though editing a replay file to be absolutely sure on the tough ones would be neat.

 

Your program sounds interesting...

 

I would certainly be interested in seeing the results of a VF based proggy like that. Any larger examples of it in action as concerns Tekken?

it works

the more I think of this, the more I think it would fantastic to see. Please break it.

Actually, it would be more interesting for Evo. Imagine the insane stuff you could create in "Hyper Battle Mode"(hopefully it's an unlockable option). /versus/images/graemlins/smile.gif /versus/images/graemlins/smirk.gif /versus/images/graemlins/grin.gif /versus/images/graemlins/blush.gif /versus/images/graemlins/shocked.gif /versus/images/graemlins/tongue.gif

 

I can't say that i can do it yet, the tekken 4 one was quite easy (noman cracked the input data damn near str8 away.).
hopefully the vf game save doesn't carry a checksum (if it does, i'm dead cold then and it's game over, it's to hard for me to crack checksum data.)
If we can crack the replay data for player 1 and 2 it shouldn't be that hard to modify the editor i've done for T4. It's nearly done, it has multi-line cut and paste, and all strings can be saved to a database.
i've added an overall running count of the frames so that you can synch p1 and p2 time times to together ( the data structure for vf will prolly be different, but the T4 way is very logical and simple, it would be stupid to do it in a massively differnet way)

when i've finished the T4 project, I'll take a look at evo,
i used to have a programmable stick which i mucked about with vf4 when it came out, i know the timing of controller input is frame by frame cause i was doing some crazy akira stuff (you know, the type of stuff that breaks your wrists)

 

VF4 Evo replay files saves the input data for both players already. When you play them back, you can set the game to display the inputs made by both players.

I assume then that this should be fairly easy to extract that data. /versus/images/graemlins/laugh.gif

 

by the way, if it's possible to hack into replay data, what about ... character edit files? Items etc?

 

Check the action replay thread, there seems to be an all item code /versus/images/graemlins/smile.gif

 

It would be more difficult for us to crack the item data and i dont see it being worthwhile. The difficulty comes from the fact that its one big system file (whereas replays are independent files). Also, you can just get someone to upload a complete save... No need to crack it...

Im probably gonna have a look at the evo replay files tonight, see if its something similiar to tekken 4 or maybe a different approach (like frame by frame reading)...

 

A "Complete" save is a bit harder in VF4E than most games. It requires you completing the Quest mode, Trials, and Training Modes with every character. This can take more than a week per character. Just saying.

 

The program that you wrote, it only allows you control over the character's move sets? can it affect position in the ring or--to any extenxt--control the camera?

There's lots of potential for something like this, I feel.

actually, all their program do is to extract the input data from a saved replay file on the memory card. It doesn't interact with the game in anyways, just files from the memory card.

one theory I thought would make for mild entertainment is to hack the replay file and give incorrect characters for P1 and P2, then see how the fight plays out with completely different moves

 

the reason i have shown you that vid was to prove i could edit atleast edit data (what other way can I show?). I doubt sega would bother to include enuff data to give chars moves of others. What you saw in the vid was a simple skin change.

you assumptions about the editor are correct in what is does and your correct in the basic format of a save game.

run the editor and load in a saved T4 replay.
see what you think.
hopefully i'll get started on the vf4 version soon
