VirtuousRage was asking me for a while to do a Translation Patch for Insmouse No Yakata (インスマウスの館). A week ago I decided to give it a go. After starting to analyze the ROM I remembered that HorvatM already did all of this: http://matejhorvat.si/en/vboy/insmouse/
Based on that data I wrote a tool that allows me to freely change every image inside of the ROM. I actually found allot more (very disturbing) images that had not been mapped by HorvatM yet as well. While the tool works for my needs it’s not in a state that allows a release quite yet. There is not too much work left though. Maybe in a week or so.
Attached you will find the patched ROM, some screenshots and a (too fast) video.
