Sorry for the delay, I had a lot of stuff going on in my life so I had taken time off for a bit.
Here is 19-28 of Jikuu Tantei Genshi-kun as XVID AVI's
There are some typesetting errors like different font's on each episode but its a minor problem and
has nothing to do with the subtitling of each episode, which is has been translated.

More Jikuu Tantei Genshi-kun will be done soon. The Earlier episodes I may try to seed sometime but I have to balance it between the new ones and these as well.
Hope you enjoy them as I have done!
Have a nice Day!
