I have yet to get the right tools, but I REALLY want to do this:
Romhack of: Pokemon Crystal(duh)
Story: You begin your journey as a Pokemon Trainer, 3 years after the events of the first Generation of games. To Collect all eight badges and beat the Elite for is the goal, but many challanges await. Team Rocket has returned, hoping to find the whereabouts of their leader. The Legendary Pokemon, Suicune, is out and about. Can you befriend it.
After all is said and done, you get to explore the Kanto Region, with all new-content never seen in the original second-gen games.
Most have to do with the Pokemon Themselves. I'm going to give them the same type of TM compatibility they have in Later Gens, Like Gyarados with Earthquake and Venusaur with Sludge Bomb(Seriously, they couldn't get those moves until 3rd Gen)
I'm also planning to add later-gen moves, but it's limited for this reason:
there are 256 Slots for moves in GSC, and 251 of them are used up already.
I'm planning to Fill up those final 5 and replace some moves with others:
Brick Break (I'll probably be unable to give it its secondary effect)
Fury Cutter with X Scissor
An Easy Replacement
Splash with Bounce
Pretty much everything that gets Splash can also get Bounce
Razor Wind with Stone Edge
The only way to get Razor Wind in GSC is to trade over a RGBY Pokemon that learned it via TM.
Snore with Bug Bite
Worthless move is worthless (Bug Bite won't have its Secondary effect)
Dragonbreath with Dragon Pulse
I'll have to change Clair's Dialouge, though.
Barrage with Sucker Punch
I'm pretty sure Exeggcute won't miss it's exclusive move. I'll have to make Sucker Punch work like a Dark-Type Extremespeed
Twineedle with Energy Ball
Detect with Aromatheraphy
Do we really need both Protect and Detect?
I'll also chang the TMs around, and add a few more Move Tutors
"But Dunsparce, how are you goign to make Space?"
Easy, by Getting rid of all of those worthless unused Beta Maps found in the coding taking up memory.
I'm also adding all the Pokemon that can only be found in R/G/B/Y/G/S to it.
I'll make a special Dungeon(s) for the Birds, Mewtwo, and Mew, add the G/S only version Pokemon to the locations they're found there, and a Special Cave with The Fossils and a Grass Patch with the six Starters.
Most Pokemon with also get a Movepool Facelift, like so:
Nice Dunsparce I also think that the 2nd Gen of Pokemon games should be apart of the hacking Community they have allot of Potential with extra space in the Rom and 2 Regions to fiddle around with I'm glad to see you are using this to your advantage with this Rom Hack I'm trying to make a unique 2nd Gen Rom hack currently I'm just undecided to do it with G/S or Crystal it all depends on which has the better tools lol
