This fully adds Cliff Cave itself. The rest of the route isn't there, but you can access the cave via the Debug Room, featuring a crudely made cave structure.
I've also modified the Rock Smash wild data to feature some additional Pokemon. The Beach has a 20% Corsola, and Dark Cave has a 20% Phanpy, among other bits. Level scaling has also been applied.
The Cliff Cave music isn't right, I believe...but I don't know what it's actually meant to use, I haven't played HGSS since it was current gen.
New Pokemon have been added and distributed across the region.
Leafeon
Glaceon
Sylveon
Coinpur - Night time on early routes over Rattata. I want to make an argument for branch evolving into Moibelle at night or if female.
Perrserker - Unobtainable for now.
Gentlarva - Ilex and Viridian Forest.
Pupal - Evolve Gentlarva.
Carapthor - Evolve Pupal.
Kotora - Mt. Mortar outside, Viridian Forest.
Gaotora - Evolve Kotora
Gorotora - Evolve Gaotora
Raitora - Evolve Kotora
Bittybat - Union Cave and other early routes.
Paraspor - Ilex & Viridian Forest

Annihilape - Trade Primeape
Pupperon - Route 36, Route 37, Burned Tower B1F
Increases frequency of Phanpy encounters to be morning/day and replace Geodude in that time span. Adds 5% Jigglypuff from Silver that was removed (you'll see a lot of silver additions, it was a very based game)
Still need to fix the Headbutt trees and fishing groups, but this is a great start.
At a glance:
- Houndour and Slugma are now in the Burned Tower. Magby is also now featured as well as Magmar.
- Ilex Forest now uses mostly Johto Pokemon, including Yanma, Ledyba, and Spinarak.
- Larvitar is now in Mt. Mortar, and Marill is now an all-day encounter.
- Sneasel is now an all-day encounter in the Ice Path.
- Misdreavus replaces Gastly outside of Sprout Tower at night. That's Routes 31, 32, and 36.
- Murkrow is now a 10% encounter on all the routes near Ecruteak City. That's Routes 38, 42, and 37.
- Route 38 also has the all-day Snubbull encounters from GS, and uses Silver's data to have a Meowth-Moibelle dichotomy later.
- Route 42 also uses Gold's wild data, featuring Mankey, Flaaffy, and Girafarig. With Murkrow at night, this route is now very Johto-y.
- Route 43 also has Gold's Flaaffy and Girafarig, but keeps the presence of Furret from Crystal.
- Viridian Forest now has wild data built from Ilex Forest.
Markers for unimplemented Pokemon to be used have also been added. Buu as a nighttime Jynx replacement, etc.
