NDS Rom Regions

How can I tell if Roms are in English?I have downloaded ones which are Europe, most have been in English, but I have had a couple where everything has been in a different language, so I have had to download the USA version.Is there a way of telling?Thanks in advance.

USA and Europe regions are mostly if not all are in English

After the ROM name, it says a tag such as (E) for Europe, (U) for USA, (J) for Japanese etc. For more tags explained, go here. https://www.romulation.org/forum/index.php/topic,1359.0.html

Some also ive heard may be Spanish due to where they were released and the defualt settings on your DS/R4. Most, if not all (E) and (U) have some way of selecting ENG as language.
