CV1000 bank extractor.

[BarfHappy]

For those who don't know what that could be, sorry.
For the others, this will extract the gfx banks from CV1000 U2 flash up to mmp.

The full specification of Cave compression v2 is now implemented. Should work on ALL SH3-based games fully, SDOJ included (hurray).

Drag and drop the u2 on the executable and it will create 2 folders, suffixed by dat and tga, in DAT you will find data it couldn t extract (corrupted flash).
All games are now supported (and it should work on the more recent games, like DFK or AK).

you can use CV1000EXR u2filename from command line as well

Drag and drop an xbox360 CAVE BIN file on it and it will decompress as well.

Take care, and i love Cave <3

cv1000exr u2filename : decrypts the banks from a u2 flash
cv1000exr binfilename : decrypts the data from a CAVE XBOX360 game (tested with AKAI KATANA)
cv1000exr type filename : decrypts the filename of either CAVE type 1 (->mmpork) or CAVE type 2 (mmpork->)

Any chance I could get source for this?

Nope sorry, there is code that is CAVE property, i cannot share
(but PC code is easier than SH3 for dis-assembly )

Ah, I should have assumed so.

(but PC code is easier than SH3 for dis-assembly )

Maybe for you I find SH3 a lot easier than x86

[BarfHappy]

And now...

Muchi Muchi Pork is supported ! (it should work for later games as well, DFK/DFK BL and AK ... perhaps even SDOJ ? time will tell)

(updated, now with file-by-file support)

[BarfHappy]

I forgot, i have a small question, in fact a request... if anyone as a raw bank file from AK i d love to know if it works with it as well ! (it is type 2 !).
My japanese 360 is stock, and i don t want to hack, so i have no access to the real data of my games.
Thank you in advance !

Anyway, it works on xbox360 CAVE compression for the wallpapers

Which file has the espgaluda 2 wallpapers?

[BPzeBanshee]

Damn, nice wallpaper.

How would one get this raw bank file from Akai Katana anyway? Dump it from a PCB or view the 360 port's data with a JTAG'ed 360 like they did with Guwange XBLA?

That would be the second option~
I have no clue about the structure of xbox360 games :, All i know is that a friend extracted some xbox360 cave ports games files to play around with a year ago, and, i remembered about them. By magic, the algorithm for the arcade CV1000 games graphics decompression works on them as well (iei, hurray for costs rationalization).

[trap15]

Oh that's awesome. You should dump the wallpapers for me

[AntiFritz]

Also this seems to crash whenever i try using it on anything not a u2 file.


The correct syntax is "cv1000ex 2 filename" (or 1 for type 1?) right?

[Barrakketh]

Also this seems to crash whenever i try using it on anything not a u2 file.

My interpretation of the OP is that it is only supposed to support u2 files, not anything else.

[BarfHappy]

Ahaha, yes this tool is crash happy with unknown sources

So, your U2 must have no modification to its header (mess up with the banks table and my tool will die)
Or your extracted file must be a real CAVE compressed texture (forget a leading byte and my tool will die).

basically:
if you have a proper u2 file like, say, espg2_u2, and have the tool in a c:\wtf\ directory:
you open a command line to your u2 file (so you are under c:\somelocation\> prompt)
and type
c:\somelocation\> c:\wtf\cv1000ex espg2_u2

if you have a file extracted properly from a cave game (that means already extracted from its container, NOT the container),
then you can type
c:\somelocation\> c:\wtf\cv1000ex 1 dfk_bl_wallpaper_1
or
c:\somelocation\> c:\wtf\cv1000ex 2 muchi_dumped_bg

to be honest, the extracted file method is not to be taken seriously, i only made that to decompress things from more recent CAVE games through their ports.

example:


I hope you manage to use it finally ^^
It s been compiled in unicode using MFC through Visual C++ in visual studio 10, so you probably would need the runtime, but if you play games you should have them already

[AntiFritz]

How do you extract files from the container first? For example xbox0001.bin.

I remember doing it ages ago but have forgotten how since.

[BarfHappy]

Sorry, but i don t know how to do that ^^;
Never got into the thing of xbox360 data exploration, luckily i have friends who did, and from them i know that my algorithm works on these

Ok, so, new version, all my apologies, a previous bug made that unrecognised compression types in muchi muchi pork were not treated as raw but were made duplicates of the previous bank... silly me.
So, instead of just patching to make raws, i implemented the missing decompression routines.
There still lacks one... sob... for 3 banks. I ll see if i can dig the code for it, i only manage to extract the final stage (4 passes instead of 3), but i don t know how to go further... yet xD

[BarfHappy]

And an important update, the implementation is now finished for Cave compression 2.
This means that unless a BIG surprise, this should work on every CAVE SH3-based game, even the ones not yet dumped.



In MMP the last subtype that made me have white hair... was all for THIS

(and a few shadows)

This is the same principle as usual, a new compression is experimented on a few useless tiles, and then fully implemented a few games later, when the need is there for extra space (these decompression routines are CPU and memory-io intensive).

Take care.

[BarfHappy]

New Version,

support for XBOX360 games (tested successfully on DDP DFK BL and AKAI KATANA)

At your own risk (2 megs), DDP BL first bank:

[Icarus]

Gorgeous pic of Shuumeigiku in the OP, though I don't recall seeing it anywhere in the game. Was it display wallpaper?

[BarfHappy]

Yes that one is part of the 25 wallpapers

Are you able to get sound effects from the X360 games? I've been looking for a high quality clip of the ninja mode transform sound effect from Akai Katana Shin for ages. :/
Good job on the bank extractor, by the way. Makes sprite-ripping easier.

Ripping music (and i assume sound effects) isnt too hard. I used a program called dragon unpacker to extract the audio.

[BarfHappy]

Ho ... dragon unpacker still exists ?
we used to reverse engineer together elb and i (we are friends from the same uni), i made the bubbles-and-bubblebobble splash a long time ago if he still uses it
He is a dedicated man... we were playing together about 12 years ago. We used to have fun making complementary tools, him the ripping, me the injection... Delphi VS VC++ ... good times.

Sorry, i cannot help with the 360, this is not a platform i am very familiar with.

[AntiFritz]

Yeah, I've been using it for various things over the years. Still has that splash screen too and afaik the programs still in development.

[AntiFritz]

Thanks once again for this program but anyway



Musou?

Also looks like they once planned on including arcade mode in the dfk port.

I might be able to hook a brother up with this. The Cave Desktop Accessory CD-ROM Vol. 1 has a bunch of clean officially sourced sound effect and voice samples and I'm pretty sure Akai Katana is included.

I'll bring it along to the meet on a USB drive.

[Aurel]

Thanks a lot for this awsome software !!
Is there a way to rebuild the u2 rom back with customized tga files?
(It could be funny to exchange some sprites )

I'm hoping someone is homebrewing for the SH3 one day. BarfHappy I'm looking at you

For the TGA: Yes there is a way to put back your very own tga files in there I did it for deathsmiles, worked like a charm. Making the proper tools will take a while though.

Gosh THE, how do you know ?
I am in the process of purchasing the toolchain from Renesas xD It is a perfect match for CAVE platform, the SH7709s is a target for the toolchain (it is readily available as evaluation software).

[trap15]

You don't really need to purchase a toolchain. You can just make a cross-compiling GCC yourself and compile a libc. Free and takes pretty little effort.

I know Trap, but considering the renesas is what cave uses... it would be perfect
I asked for rates though, if it s too expensive i ll do it the old ways and all in assembly (aaah the c64 ...)
