I am trying to extract the palette from Tomb Raider 1 for the PlayStation, but I'm not sure where to begin. Using Peops soft GPU with epsxe, I took a snapshot of what was in the VRAM. The snapshot is below, but I had to convert it into .png so it would load on the board faster and Photobucket shrank it to 800 x 600.
I am guessing the palette is the stuff I have boxed in green spray paint in the picture below:
Am I correct in my reasoning?
And would my palette be 768 bytes or some strange larger number?
I am assuming the "rainbow lines" at the bottom of the block I surrounded with green spray paint is the end of the palette (if that really is the palette).
However, I am having trouble trying to figure out the ending hex address of my "palette".
Using Tile Molester I was able to figure out that it begins at hex address 0009E978 but I am having serious trouble finding the ending address.
I found the beginning address by opening the file GYM.PSX and viewing it using the 16 bpp ABGR codec in 2-Dimensional mode. I scrolled down until I could see my "palette".
I then switched to 8bpp linear and went down line by line by going 128 bytes relative to where I was. I found that my "palette" begins around 0009E900 but the first dot was all the way to the right, so I shifted left 120 times. Every time I shifted left I added how many shifts I made to the hex address where I was. Of course when I was finished shifting I would then close the file and not save it, because it has been my experience that whenever I shift stuff Tile Molester does something weird to the file and puts the data out of place.
So 0009E900 is 649472 in decimal.
649472+120=649592
649592 is 0009E978 in hex.
"palette" begins at: 0009E978
I thought I could use that same logic in finding the hex address where my "palette" ends but I was wrong (in this case I went down line by line until I could no longer see the "rainbow lines").
I THOUGHT the "palette" ended at 000A1778. So I opened up GYM.PSX in Hex Workshop, went to Edit --> Goto and selected Hex and Beginning of File and entered in 0009E978. I then went to Edit --> Select Block and selected Hex and Ending Position and entered in 000A1778. I copied and pasted my selection into a blank file, saved the blank file, and opened it in Tile Molester using the 16 bpp ABGR codec in 2-Dimensional mode. Everything seemed fine, except that my "rainbow lines" aren't there!
So today I copied and pasted the “rainbow lines” into temporary separate files including extra zeros (due to blank space left behind by Tile Molester). Whenever I copy something, I make sure I copy it into a new blank file that uses the same codec I am using at the time.
I view the data using the 16 bpp ABGR and 8bpp linear codecs and the “rainbow lines” appear along with the black space left behind by Tile Molester. But after I remove the extra zeros the “rainbow lines” disappear. However, their bits of data can be seen in a hex editor.
What's up with that?
Can anyone find the ending hex address and teach me how they did it? I'm willing to send the file if need be.
