I scanned my Battle Saga Field Ver.1.0 and working on cleaning it up in Photoshop. My goal is to overlay text in English so we can print them out. Since I have a Colosseum, I'm planning to make a playmat like you would use with Magic the Gathering.
After I get the board done, I'll move on the rule book and dice explanations.
If anyone wants to help me translate, post in the comments. I'll post my work in progress and final downloadable images here.
