I'm searching a GUI version of it, but the Modified 3DSExplorer (GUI) link of this thread http://gbatemp.net/threads/3ds-rom-tool-rom_tool.349314/ is broken (both), and the cmd version is a bit complicated for me. So, anybody has a link (I know that rom links are forbiden... but utilies links?) to spare to a GUI version of rom_tool? And there is any list of reference showing trimmable and non-trimmable games? (I know that CARD2 are not-trimmable-wise) Thank you very much. Edit: I know that 3DSExplorer (vanilla) can trimm to, but it doesn't show card-type (card1 or card2) of the rom.
