PsyKo has updated CTR, a small PC utility designed to read and display basic info from Nintendo DS, DSi and Nintendo 3DS ROM dumps.
Changelog
v1.5.2 - Accepts 3DS homebrew ROMs - Small bugs fixed in NDS/3DS header reading
v1.5.1 - Few new "Maker codes" added/edited - Accepts 3DS ROMs with ".3dz" extension
+ Notes: - Trimmed and ripped ROMs are both working on the Gateway flashcard (tested with launcher v1.1) - Since every tool got its own way to trim ROMs, we advise you to only un-trim the 3DS ROMs that you trimmed with CTR. - If you RIP updates, remember that the update partition will be deleted permanently and can't be restored.
