if u are talking about the parts i translated already, they are all inside the executable.
To find the ingame text was easy by studing the files name and drastically rename the files on the pc version till the game crashed/freezed or just not continue on the first dialog of Hiro.
Then look inside that file to see that (like the whole serie), every file has many more sub-files inside of them and all the pointers at the beginning of the file (some have even 2 pointer tables if i saw it right). So i started put some zeros on each pointed part inside the file till the text gliched.
Latelly (and probably for the next 2 months) i will be pretty busy in rl but if u could compile your decompressor for window, we could try on the file part that I have pointed out. If it's working, i will give u more details about the file format so that u could complete your decompressor in decompressing all sub-file inside a file by reading the pointers. Like that it will be faster to find the rest of the text and other texts/graphics that need translation.
