Would it be possible to fix the Replay unpacker

[OshidaBCF]

A friend wanted to make a TacView integration for the replay system, i can make one that would work off the "web map" but i'm missing informations.

So i was wondering if i could make one from a replay file, but i would need the unpacker to work for that to happen

Do you have an exemple of already "extracted" replay, i want to see if there is data that i can use or if everything i would need it missing?

File wrplu.bin is an unpacked replay stream.

I get an error if i use either normal or _ng, is yours different than mine ?

[OshidaBCF]

strict_blk doesn't change the error

What is the value of the byte pair at offset 0x04c4 in the replay file?

[OshidaBCF]

0x04C4 is 0A

I re-downloaded the vromfs files and format, but error is still here.

[kotiq]

Okay. I will ignore this pair as a constant.

Here's the replay in case of

That single line fixed it.

I can extract the files correctly but now i don't know what to do with the .bin, it seems to be encoded

[kotiq]

The file contains a list of nodes.
I can extract from it what I know partially, such as the blk sequence of the decals or decorators location.
I haven't dealt with the wrpl format, I think it would require a lot of reverse engineering.

[OshidaBCF]

Hmmm, what i would need would be positions of planes and missiles, i can probably link each plane with a name using the blks. Thanks

How it looked six years ago.

[OshidaBCF]

Jesus...

Also what does the "replay_db" folder do ?

Make a database from a replay ?

I think at the time I was calculating the battle rating range of opponents participating in battles based on a set of replays. I'm not sure if this works in the current version.
