First of all, I wanted to thank you, I usually play Emerald and never done Ruby before, and your hack got me into this game for the first time :) Sure sometimes there are some bugs of textures and it can be really odd, but I see more than this, to me, there is the passion behing the hack and you sure have it, I know people may criticize your work but don't let them discourage you, what you've done is amazing really, believe in yourself you can do it to the very end and this will be the moment where you'll be proud of you, and you have to because you deserve it very well for all your hard work :)
Truth is, not many people can say they've done things you've done, rom hacking is for yourself too, not only for others, and that's why the fact it pleases you in itself is a great thing, furthermore, I'm sure it please lots of people too, so believe in yourself, you can finish it ;)
Now, for the playing part, I'm not used at all with the new mons but great work for implementing them, and the Johto part is a really good addition to Ruby (RSE in fact), I'd love to play it from start to finish :)
