Grid Idea - PS2 Campaign Grids?

[Rezdj]

Does the PS2 version have different campaign grids compared to the PSP version? If yes, it could be an application to your proof of concept grid addons !
edit : Belmondo's vision can open all of the Wads from the ps2 versions.

here are the grids of the ps2 version, i don't know how to pack a them in a wad so i leave these here if they pique your interest.

grids from the release ps2 version (not the padz2 which is also different)

Padz2

interestingly the other ps2 prototype has different grids and parameters

I wonder how different the psp proto's grid are

Thanks a lot for providing the grids!
Personally, I would not use them since it may make the game more unstable than it already is.
The Statistics crash, the disappearing HUD etc can all be encountered in the original game as well. I didn't know there were so many problems reported back then at WipEoutZone (Rob Foxx himself was very critical about this).
The grids and all their cells in the custom DLCs had to be renamed aswell, or it would cause these kind of issues (with 100% complete official PSP campaign saved in the profile):

Remember it makes permanent changes to the profile to store the campaign records, for that many grids it's possible it could potentially make Pulse even more unstable and mess up the profile, so that's why I think it's a bad idea. Although hardcoded to a limit of 5, the custom grid feature would be better suited as it won't alter the saves, it's saved in the custom grid instead.

Anyone can make their own packs for WipEout Pulse, using wadutil and packing a .wad renamed to .EDAT:
wadutil.py --create DLCPack.EDAT --zlib-compress DLCFolder
You can find the compiled .edat and original folders for the grids in the following .zip file (each separated for the two PS2 grid versions and the three known PSP prototypes (01/05/07; 31/05/07; 31/08/07)), only one of them should be used at a time: Custom DLC Grids.zip
All the file names from .wad files I could find are available in the Documentation folder at MEGA.

The WADSP and WADS2 .wad in Pulse PS2 are standard .wad files, so they can be extracted with wadutil like any other ones, same for F1 2006 (same studio, same container format but nothing else seems similar).
However, I found that Pulse PS2 uses a different version of the WAD format for the music tracks and race intros (PS2MUSIC.WAD (16 files) and PRERACE.WAD (32 files)).
They start without the WAD version number, just 4-byte for the number of files at the beginning. It seems to be structured like this for each index entry: uint32_t hash; uint32_t length; uint32_t start_offset. The hash calculation may also be different.
The tracks in these .wad are exactly the same as the .wav from PADZ2, but with the 44-byte WAV header removed.
I managed to reverse 5595 filenames out of 7200 in WADS2.WAD, and 175 out of 193 in WADSP.WAD. It may looks like a lot are missing, but it is almost certain that all remaining filenames are actually unused files, finding the rest may be next to impossible since we don't know what to look for but also not be really useful.
This version uses .twd (Tex Wad, exactly identical to .wad) files for environments and ships, they are texture containers for .vex files sharing the same name. But almost all file names missing are for .pct textures, but since the game uses instead TWD these .pct files are actually useless and wasting a lot of space.

For some of them yes, but I think the .idx were from an earlier version of the .wad files as they were missing a huge amount of file names.
What was more useful was 7zip with the list files command (7z l archive.zip > output.txt), with it I could reverse a lot of them and also by opening in HxD the executable (it's already unencrypted) to see the PS2-exclusive files the game looks for.
I think they (Spiral House) didn't care about wasting space like this since the game would be stored on a DVD, it's possible that by getting rid of all duplicated/unused files the game would take only something like 7 or 8 hundreds MB, but trying to improve in any way this port is a lost cause and a waste of time since it's just too broken.
For the "Half/Full Grid" option, its original purpose seems to modify the number of AI ships from 7 to 3 and vice versa.
I tried to restore it in Racebox, but it doesn't work anymore in the final game.

[Rezdj]

okay... interesting. Too bad the half grid option doesn't work anymore. Is there remnants of it in the PS2 version (it's to document it properly on TCRF (and my HDD containing the dump of the PS2 version is currently dying considering the noise it does)) ?
Thank you again for your mod !
Edit : By curiosity, what's the big changes for 3.0 ?

[NR74W]

Thanks! About the PS2 version, the only thing I know is that it still has the original PSP Concept ships left unused, but nothing else.
Considering how time-consuming the PSP mods were, I don't want mess with Pulse PS2. It was enough, and hoping to never touch modding again.

Among what's new in v3: supErphoniX2 font remade and now 100% accurate in WipEout Pulse; Added credits names from US version in WipEout Pulse; Restored menu layout in WipEout Pure; Some localization strings fixed; WipEout Pure and Pulse now available as separate patches; File size optimization (it may not be possible to decrease further the game size); Restored "Karbonis" name; Added the "Welcome to..." race intros for WipEout Pure DLC in Pulse; Rebuilt all DLCs; New DLCs; ...

[Rezdj]

ooh okay! nice ! can't wait ! To be honest pulse ps2 don't really need modding in the first place considering your mod being superior in every way! thank again !
Edit : sorry to sound like a broken record (again) but don't hesitate to join the AGRF discord, there are people as dedicated to WipEout as you are there (and if you sometimes play online on pulse, HD, 2048 or OC, there are online events) !

[Rezdj]

By curiosity, is 3.0 the theorically last update or there is still things (outside of bug fixes) ?
edit : do you still have the older version of your mod or these are lost ?
