1 Get a small sample of the RAW image data
You can do this by loading a non-compressed emulator save-state in nana. Emulators may differ a little, but pSX v1.13 saves the Video-RAM near the end of the save. This V-RAM is best viewed at 'raw:byte' 2048 wide. You want to locate a sample of the text-graphic from it's middle, and NOT just blank-black pixels. It should look something like this, note the location:Copy RAW data segment
Open the save-state in a Hex Editor and go to this location and copy a SMALL segment of hex data from the location. This data should be segment from a line of pixels. Copy it:Search CD image for data segment
Next, open the BIN disk image in the hex editor and search for the copied data. If all goes right you should find it:Calculate which file
Next, you need calculate which file this data is in. To do that, take the location in the CD image and divide it by 0x930. Example: 0x7b37d48 divided by 0x930 = 0xd695 = 54933.
This result (54933) is data's LBA. Open the CD image in a program like CDmage and sort the files by LBA. Look for the file whose starting LBA is just below the data's LBA:Locate RAW segment in file
This is the file where the image is located. Open that file in a Hex Editor and search for the same hex data. Note it's location:
Now, open SIGE_TIM.BIN in nana and go the noted location. The text you're looking for is there.
Luckily for you, these text-images are standard TIMs but missing a header tag. You could extract them 1 by one with RawToTIM, but it would take quite a lot of patience. So I have a suggestion: "Search and Replace" in a hex editor.
First search for 10000000 08000000 2C000000 and replace it with 12345678 12345678 12345678. This replaces existing TIM headers with a byte sequence not found in the file.
Next search for 08000000 2C000000 and replace it with 10000000 08000000 2C000000. This will add the missing tag to the text-graphics TIMs which should make them show up in TIM-viewer:
When you are done with your edits, reverse the procedure.
Search for 10000000 08000000 2C000000 and replace with 08000000 2C000000. Next, search for 12345678 12345678 12345678 and replace with 10000000 08000000 2C000000 to restore the original TIM files.
