Hey guys,
Recently I've taken in interest in what I think is one of the greatest PSP games ever made.
It's Mobile Suit Gundam Ghiren's Greed Axis no Kyoui V. Picture Romance of three kingdoms
or Nobunaga's ambition with a Gundam overaly.
The Cool thing is I'm fluent in Japanese, and I've taken the liberty of extracting and translating
the majority of the Menu's, major decisions and pilot data(This is all stored in images,
the game has very little text and most of that is in the EBOOT.bin)
A ton of text still remains untranslated (mostly pilot dialog etc.)
The issue is I used a program that I found on a Japanese site to extract all of the images.
The program has no option to re-compress and insert the images I've translated.
Here is some of the technical info I've figured out:
The Game major storage system are large MKD files, this is where most of the images and game data are found and inside everything is stored in SD0 Containers The other major file is the MIF file which keeps track of all SD0 containers spread over all the MKD files. It does so in a weird way that I dont fully understand (yet) but generally, it keeps flags to tell you which file is in which mkd file... and where in the mkd file its located. It stores that value as a block number (2B) that gets multiplied by 2048 to get the actual offset, from there it jumps into the mkd(SD0) files...
The SD0 Files inside the MKD start with a 4B "SD0-filesize" And another 4B that I can only assume at this point to be some kind of descriptor. Followed by a 1B flag that tells the filetype that follows... and then the actual payload which again, branches into several other subtypes.
At this point I'm fresh out of ideas of where to go next
if anyone is interested in assisting let me know.
I've attached an image of the SD0 hex dump.
also upon request I can send the program I used to extract the images
