I have found several bugs with the Ruby Patch, using the most recent patch. Here's the two I've encountered
1. Torchic's sprite showed Ralts instead of Torchic.
2. Wurmple showed Nincada instead.
Not sure if this is the patch or the ROM or what, but here's a ss to at least confirm Wurmple as Nincada

I didn't screenshot the Torchic, however, but it WAS a Ralts. I'll update this to tell if any other sprites are all weird.
