Drag & Drop on Trb2xlsx.exe to convert TRB to XLSX and back to TRB. Add text replacement/translation at column C. Check 'lookup.txt' for supported characters, for instance '?' is not supported, use '？' instead. Either use ALT+ENTER or paste the ◙ symbol to create a new line in the game. Make sure you close XSLX before you try to convert file back to TRB. For edited textresource_jpn.trb file to load successfully use included code.bin plugin and also add the modded textresource_config.trb in (NLP+)**\SystemData\TextResource**.
