I just pick from whatever games have been posted in the Eroge discussion subsection.
For kanji that I don't recognise, I use the Google Translate app on my Android phone. It's handy as it comes with a handwriting recognition feature so you can try copying the character into the app and if it's close enough out pops the kanji as text - and just tap the translate button then voilà!
Personally I find this method quicker and more accurate than using optical character recognition tools, and helps with learning how to write kanji as well
