Ah My Goddess (PS2)

This game's models and textures appear to be stored on GRP.bin and there's no script/tools made to extract its content. It seems to have a list of names of its content at the beginning and the data it contains has a 'PKv0' header and they may have some kind of compression. I can find vertices of characters in Model Researcher but they come out flat probably because of that compression. I get better results on the vertices when I open the eeMemory with Model Researcher but I couldn't seem to find the faces. Would it be possible to make some script to extract the model/texture files from the eeMemory and at least get the meshes displayed on Model Researcher? It would probably be harder to get the models/textures from GRP.bin though because of some compression it may possibly have. I have also taken a portion from the eeMemory that I think contains some mesh data and I have made a list of offsets, counts and paddings where I can find some possibly proper vertices.
Here's the portion of eeMemory:
eememory_part
Code: Select all
for eeMemory_part
offset: 0x12a2c4
count: 19
padding: 84
offset: 0x12ac48
count: 15
padding: 84
offset: 0x12b44c
count: 15
padding: 84
offset: 0x12c394
count: 16
padding: 84
offset: 0x12cbf8
count: 28
padding: 84
offset: 0x12d8dc
count: 17
padding: 84
offset: 0x13fb00
count: 8
padding: 84

The entire
eeMemory and
GRP.bin
There have been a few mentions of this game here a long time ago but they didn't really got anywhere and nobody had taken a deeper look at it.

i made unpacker 'GRP.BIN'
(I'll look at the unpacked files later)

Sorry for bumping but, any news on this?

I managed to extract 3d models from pcsx2 memory dumping.
And wrote a simple maxscript to build 3d models without weight data.
Searching old disks atm,,not sure if i still keep the scripts..
I posted it on mariokart's forum,,which was closed.
what i remember is,,before the header,,there are few values need to be saved as array..
then you have to add those values into your polygon face index read from raw data..
That will be the real vertex index to generate 3d models.
ripped model.

do you remember what the forum was called? maybe its archived somewere?
anyway I think it would be better to go for the memory dump or eememory because the files in the grp.bin appears to be compressed (unless someone is willing to figure out the compression)
anyway hopefully you'll find the script

Also,,I remember there was Dreamcast version,,I had few samples remaining,,if you want to analysis them too.

Thank you very much for sharing, I'm really glad you found it
anyway how do I get the memory dump that will work with the script though...

I remember some hexeditor had ability to do it.

to rip the hex data for pcsx2,,you can use cheatengine.
https://cheatengine.org/
my OS got reinstalled lots of times..3dsmax is not installed atm.you have to wait a bit when i have time to check the scripts line by line later after i reinstall it.but file structure should be correct since i used it construct the models.

try to use maxsript cutsume2 import.ms
in the sample file i sent,,excute it and open cutsume2 import.dat
lots of things i don't remember it well now,,b/c it's ripped hex data,so it's file structure is not compelete..have to set a correct location to start reading the file,,,sorry,,it was done more than 10 year ago,really don't remember it well.

Its fine if you don't remember everything since it was a long time ago, I understand that.
I highly appreciate your help and I'm really grateful for that.
