[Holy_Diver]

The points that movement becomes slow:
* Waterfall Area
* The fountain of Thedeck
* Central Forest Area
* Near the King Harvine
* Entrance to underwater area in Lost Lagoon
* Library (very very slow)

Maybe, because my PC is powerless.

These are Todd's (the author's) fault. A game should be more consistent about it's system requirements.

I am interested in it.
(But I am worried whether my poor English is useful for the project.)

You can do like most game companies and just make things up as you go. At least if done by a native speaker it will feel correct. The translation can always be made more accurate over time. It's actually best if you could just get it done quick as possible however that is easiest for you.

When my environment can be prepared, I will.
Maybe I can do it soon.

When Todd does dump the text, I think he will find many writing errors he will want to correct first. That may take longer than he expects.

If Mr. TheYellowBrickRoad does it, it may be quick.
When I do it, very takes time.
If you accept it, I will do it.

He could do it fast, and you could correct his mistakes. Unfortunately I have not been able to contact TYBR in a long time. He did email the Nekomimi project once for information. He has disappeared from the internet however. I can give you guys his email in case you have more luck. He might be more sympathetic if Japanese people begged him to help. I will email him again also.
