If user has been bought professional license of
IsoBuster, he can use custom signature script engine to be used as Memory Card and Saves finder. In attachment You can find
Save Data Crawler which can be used to find
all PSX and PS2 Memory Cards formats,
all PSX saves (PS2 saves doesn't have signatures) and PSV containers. Script can be used in none-commercially and even commercially; You are totally free to use it whatever purpose You want. ^^
1. Run the app and go to "Options" > "File System settings" > "SIG".
2a. Check option "Limit the size of found files to:" and write "65536" value.
This is because largest VMC created by OPL cannot be larger than 64MiB but of course if You know that used virtual memory cards are larger or smaller, increase or decrease this number (i.e raw PSX memory cards cannot be larger than 128KiB, so if You looking only those, write "128"). Engine trying guess the file size but technically it is not possible to always automatically determine proper size so found saves or virtual memory cards can be larger than they really are, because there are other data between their signatures and next found signature.
2b. Check option "Use custom defined rules" and choose file "Save Data Crawler.rules" from Your disk (which You must of course download and unpack from this post). To eliminate possibility of false positive scan results, also check option "Only custom defined rules".
2c. Click "OK" to save changes. ;p
Note: if You always want to use this script, in addition, without any limitations on demand like size etc., put *.rules file in "Plugins" dir where You have installed IsoBuster. It will be automatically read on application start.
3. Open disk image (by "File" > "Open Image File ") or real device like connected disk, pendrive etc. (by clicking on "Select a drive"). IsoBuster will interpret image/device logic. If it is unknown or beyond repair You can scan only whole file/device, but if it understandable, it will show partitions/areas and user would be able to choose scan only selected part of data.
In example below, it is disk image comes from PS2 HDD. Knowing that only on "__common" partition I have PSX memory cards, I selecting this specific partition to shorten scanning time. Under right mouse menu, I choose option "Find missing files and folders".
4. After scan is done, under rectangle symbolizing file system type, appears rectangle with "SIG" letters. This is place where You can find all found files by signature scan and under right mouse menu on files, be able to extract them. On example below, there is PSX memory card image and several PSX saves.
Note: none of the files have original file names because those are not part of files but file system tables which aren't used for signature scan. Also file size could not be true (some can be larger than they should). It is totally normal behaviour.
Note2: if looking data was fragmented, recovered files can be "damaged" because algorithm doesn't know where another parts of data are. Signature scan always works best on not fragmented files.

\% Place this script inside Plugins dir where You have installed IsoBuster then use on selected track or partition "Find missing files and
\% folders". After signature scan end, new square "SIG" should appear with found data. None of the files will have original file names and
\% will be duplicated with already visible data. That's the normal behavior and nature of file seeking by value patterns.
