Frogger 3D PSX MWD

Post by Miles2345 »

I think this file is uncompressed unlike the PC version. I see tons of headers in it. Thanks in advance.

I just realized I've posted this like 5 times on other sites over the last three years or so. I guess I'm desparate :roll: I'm almost certain this can be done, even without filenames. I just really want the files themselves.

I should really be learning how to write BMS scripts for myself so I don't have to keep bugging everyone else about it, I feel really bad for that.

When I try to download it my browser locks up upon trying to load the link. Could you try uploading it elsewhere?

Perhaps try right clicking the link and saving as?

If that doesn't work, there's also this:

I don't see a table with information about the files like offset and size.
There is just a simple header and then from offset 0x800 there are just the files (2GRV, pBAV and so on).

So... there's no way to just split up the file whenever it finds a header, or something along those lines?

I should've tried that before, worked perfectly was really quick :P

I personally can't see a good way to split the files up unless we knew all the header magics. Even then I'm not sure how well it would go, there seem to be big null chunks in between some of them (not sure what for but probably some sort of padding).

Are there any smaller files near this one? Maybe some sort of index file containing names and/or offsets and sizes?

The only files in the game are musics in STR format, the MWD, and the executable. I took a look at the executable and I couldn't seem to find any sort of file index at all. I found some strings "PACKEDRESOURCE", but still no sign of a file index. This game is evil.

However, I did some time ago find a file index in the PC port of the game, however I think the PC version is compressed or stored differently, and nobody had any luck with it on any places I posted it.

Perhaps someone can find something in the executable? There's TONS of filenames, everything in the game. I don't know if there's any info relating to offsets and sizes, but it must mean SOMETHING. The MWD in the PC version is compressed. http://puu.sh/eL5kH.zip

I've been at this game for now like three years and I really hope this can be figured out some day :s

"MWI ACOSTABLE", yes the table is in the exetable.
Can you upload also the psx executable?

Script created:
http://aluigi.org/papers/bms/others/frogger.bms

Notes:
  • The PC version contains names, the psx one doesn't.
  • The PC version uses files compressed with powerpacker, the psx one doesn't use compression.
  • Powerpacker (PP20) currently is not supported in quickbms or the version implemented (comtype
    amiga_powerpacker) doesn't work with these files, so I will add support for it in the next version.
  • Only the files in the PACKED folder are compressed
Don't worry, there is a stand-alone unpacker that you can use from command-line:

With QuickBMS 0.6.2 being released, is PowerPacker support available?

Thanks for the bump, I forgot this thread.
Yes powerpacker is now available and I have just updated (and tested) the script :)

Did something break? I get this error now:

Code: Select all

-error in src/file.c line 243: fdnum_open()
Error: No such file or directory

Last script line before the error or that produced the error:   8   open FDSE "SLUS_005.05" # PSX

Other scripts work just fine, so...

The game executable (frogger.exe or SLUS_005.06) must be available or the script can't extract the archive.

Ah, I had not realized the need. Thanks!
