It's said that right now it's best to be played on an Emulator I also have it on Rhea will test it and see if that happens here too.hey great work on the grandia English translation. I am playing on real Saturn hardware and have come across a bit were the game is not going into the battle like it should and wont move forward. I have tried restarting and booting it from my last save point but it got stuck in the same place again. it happens in the lost world section, when gadwin comes you challenge him to a fight but the fight doesn't begin and the game wont allow you to press anything. the music still plays and puffy is still circling the Cauldron but apart from that its like it has frozen. apart from that the game has played excellent up until that point. I have it on video but the file is too big to upload it here. again the work you are doing is fantastic and hope the information I have provided will assist you in the beta testing.
Upload the file to something like Dropbox, Google drive or Onedrive
