Frank Snow made his newly developed Chatta Sangayana Tipitaka v.4 very accessible. Especially when it comes to the dictionary. Here you can find a zip archive containing Buddhadatta’s Concise Pali-English and English-Pali dictionary in the correct format for the CST4. Just unzip the file and remove the number at the end of the dictionary file you are going to “activate”. Start the program and it will automatically access the new dictionary.
