When you start a new game in Tomba Special Edition, the front-end will load a default save state which begins at the intro cutscene (after the first loading screen in OG) these replacement stt files will start from the same point but have AUTO text option activated (which allows for much faster text mashing than the default option of FAST)
this is (on current patch) the only way to activate AUTO text unless another way is found to access the original Tomba title screen, you can also downpatch on steam to access it again, hopefully this is temporary til a patch gives us the option to change the text speed again in the front-end menu.
included is an STT file for each language option
right click game in steam and go "Browse Local Files" open assets\game and replace all stt files with the ones in this archive
