Have you tried going to options and see if the language is still set to English? Sometimes it changes it to Japanese without me asking to.

The only way to fix it is to update your card's kernel. In the case of a DSTT clone/YSmenu/anything that uses extinfo.dat and infolib.dat, just replace those files with the ones linked to in the first post and it should work. Alternatively you can try to get Retrogamefan's firmware 6.80 to work on your cart and replace the dats in the TTMenu folder with the ones in the first post.
