Emuera-Rikaichan
Emuera-Rikaichan is Emuera-Anchor modified to show a dictionary popup for words as you hover on them. A much better alternative to machine translation, as long as you know basic grammar.
Right now it is a part of EvilMask's EmuEra fork: https://gitlab.com/EvilMask/emuera.em
To enable popups, download and extract File:Emuera-Rikai-dictionaries.zip into the same folder with exe, then go to Help -> Settings -> Dict -> Enable popup dictionary, then click Save and Restart.
Dictionary files are taken from the JMdict-EDICT Dictionary Project http://www.edrdg.org/wiki/index.php/JMdict-EDICT_Dictionary_Project , only EDICT format is supported at the moment, not the EDICT2 format.
