Using the tutorial I managed to throw together a Danielpack of Rivervale + Misty Thicket upscaled 4x using gigapixel. I think they look pretty neat, but to each their own, obviously.
Link here, again just put the s3ds into your P99 dir. Backup your old ones just in case.
Big thanks for the tutorial bro, this is a really neat project.
Apologies if anyone already did Rivervale/Misty lol.
