Japan-only manual translations would be a good idea. There's still a lot of games being translated, and many of them I'd like to put on neohucards or have pressed properly. Having manuals to accompany them would be perfect. I know a few people that would be able to do the translation.
On a related note, I'm still looking to have new hucard armtray inserts made. Haven't invested much time in this project yet though, but as soon as my wife and I get moved outta this shack in Isabela, I'll be looking into doing all of this.
