Yes.First of all thanks for this awesome piece of software.
Secondly I am trying to get the boxart working on the latest (yesterdays') release. I downloaded this pack:
https://www.gametdb.com/download.php?FTP=GameTDB-ds_box-US-2019-09-04.zip
And extracted it in the desired location (sd://_nds/TWiLightMenu/boxart) but my DSi just displays some jagged lines for the games that it find the boxart for. Am I using the right source?
