Thanks for your kind offer! I gladly accept it. =) It took a while to figure out the font, but it is the "Myriad Pro" Family, I'm 99.9% sure. I also managed to archive/dump some more text files (PNGs), but it seems, if you change the language, even the equal text PNGs (English & German) get another filename at each language. First I thought all the PNGs (just not the buttons) are working in the German version. But I must say, nope they didn't worked at all, I had to rename almost all (even grass and bush textures).
Many text PNGs are already in the released package from post #1 in this thread, but I couldn't find the file "SX4P01_82f43be6_2.png" [= p s t x] in the German version, as an example. So I renamed some of those PNGs with many letters in one file, to get them work in German, because they are 1:1 the same, in better quality. I left some other English words PNGs out - makes no sense to rename them, would result in German to English texts. The good thing is, I found some of them in German! I checked all menus and made some fights. Some text PNGs I couldn't get are "Level Up", "Skill Learnt!", "MAX" etc.
So here are the files.
More complete, but still incomplete German text Dump:

Would be nice, if anybody who is more at the end of the game, could dump some missing German PNGs. I'm at the very beginning with one dude (girl died) on the next big field. I don't want to use a endgame savegame or something like that. =)
Maybe some find it useful for themself, my German "Renamed" Package - Incomplete!:

Caution, there are also all my button configuration files included, which will most likely don't fit for anyone else but me. Delete them if needed! In total it's the main Retexture package + the PS3 buttons (+ my L1 button), just renamed for PAL German and my controller configuration, which looks like that:
With that, everyone could rename them to the desired button configuration or even get to know which name it uses. Just copy them as known and they should work if you check "Load Custom Textures".
If it matters, I use the 30 FPS patched version. I got a bit asleep with 25 FPS. This reminds me of a long forgotten time. The very first Metal Gear Solid on PSX.

I firstly played the NTSC version (which came out some month before PAL) a long time on a friends PSX. Later I got the PAL demo from a magazine and from the beginning on I was on my search for the running button, but a bit later I found out, I already was running. It just was a crappy PAL version as we know it, everywhere slower than NTSC. That's why I like to play NTSC games if I can. Even if PAL games are now a bit better with some tricks. ^^
