Many people have been getting anxious for an update and trying to make their own unofficial updates.
lol I hope you're not referring to me!
Anyway, I was about to post more about what I found while testing the GCT but it seems like you guys already beat me to the draw with most of it, especially with Red. He still appears in the background and throws pokeballs when they try to do their down B. I'm using PM's most recent module files, too, so there's probably a different file that removes Red.
Anyway, as far as gameplay goes, I'll just wait until PM:DIY is finished since I'm having trouble fully transferring just PM. I'm making a PSA, so I've really wanted to use PM's debug mode to actually see the hitboxes.
