UPDATES ON STARK CHALLENGE:
Update 1
I did all of the introductory stuff on Emerald. Started with Treecko and played up until I got my Pokeballs. I went on to catch a Poochyena I named Robb. I boxed Treecko and made Robb my Starter. Afterwards, I generated a Murkrow I called Bran and a Sneasel I called Arya. I also picked up a Zigzagoon to use as an HM Slave.
I made my way up to Petalburg City, catching a Seedot along the way. My Seedot was named Ned. I did the whole Wally story and made my way through Petalburg Forest into Rustboro City. I level grinded in and around the area until Ned evolved into Nuzleaf. I picked up Cut, taught it to Zigzagoon, and made my way to the Rustboro Gym. Ned made short work of Roxanne. I saved Peeko from Team Aqua, rescued the Devon Goods and accepted the tasks set for me by Mr. Stone (Steven's letter and Captain Stern's Goods).
I made my way back to Mr. Briney and set off for Dewford Town. I arrived in Dewford Town and delivered the letter to Steven in Granite Cave. I quickly went back to Devon Corp in Rustboro to collect the Exp Share and went straight back to Granite cave to level grind. I got all of my Pokemon up to Level 20, evolving Robb in the process and Bran made easy work of Brawly. I healed up, went back to Mr. Briney, made my way to Slateport and saved the game on the beach there.
Update 2
I trained up a little on the beach, beat Team Aqua in the Museum and delivered the package to Captain Stern. I level grinded until I met May underneath the Cycling Road and beat her in battle. I then fought my way up to Mauville City, beat Wally and trained in and around the area. Once I had all of my Pokemon up to Level 30, I took on Wattson and I beat him, though his Manectric almost killed Robb (Robb survived).
I picked up Rock Smash, made my way to Verdanturf Town, and helped Wanda and her Boyfriend. I picked up Strength and made my way up to the Fiery Path. I then fought my way up to Fallarbor Town, met Lynette, and did the event with Professor Cozmo in Meteor Falls and Teams Magma and Aqua. I then made my way back through the Fiery Path and up to Mount Chimney to fight off Team Magma. I beat Maxi and his goons with relative ease.
I made my way down to Lavaridge Town and saved the game.
Update 3
I trained up a little bit and took on Flannery's Gym. I beat her easily enough, though I accidentally sent out Ned and almost lost him. He lived though. I healed up at the Pokemon Center, collected the Go-Goggles from May before training up a little bit more.
Once all of my Pokemon were at Level 40, I made my way back to Mr. Briney and he took me back to Petalburg City and the Petalburg Gym. I beat the trainers in Norman's Gym and took down dear old Dad. Although, his Slaking was a tad bit difficult to brake down. I then picked up Surf from Wally's Dad taught it to Zigzagoon, and trained in all the new areas now accessible to me. I picked up Ice Beam from the Abandoned Ship, made my way back to Mauville and did the New Mauville event. I saved the game from there.
Update 4
I trained and level grinded all the up to the Weather Institute and did that event. I beat Team Aqua, collected Castfrom (which I immediately boxed) and started to make my way up to Fortree City. I fought May, collected Fly, picked up a Leaf Stone hidden around the area (for later use) and finally got to Fortree City. I met with Steven, picked up the Devon Scope, caught an Absol just on the outskirts of Fortree City who I named Sansa. I trained up my Pokemon a bit, made sure that my Pokemon were each level 45 (Sansa was Level 35) and took on Winona's Gym. I beat her with relative ease and fought my way down to Lilycove City.
I healed up, made my way to Mount Pyre, beat Team Aqua there, and collected the Magma Emblem. I made my way to the Magma Base near Mount Chimney, beat all of the Magma Grunts, and made short work of Maxie. Groudon was awakened and took off.
I flew to Slateport where Archie stole the Submarine and I followed them back to Lilycove City. I infiltrated the Aqua Base there and beat all of the Grunts. Unfortunately, Archie was able to escape. I healed up, surfed to Mossdeep City, got to Shoal Cave, I caught a Spheal I named Manderly, and got back to the Mossdeep Pokemon Center to heal up and saved the game.
Update 5
I trained up a bit (Manderly especially) until Manderly evolved into Sealeo and took on the Mossdeep Gym. I beat Liza and Tate no problem and made my way up to the Space Center. I took on the Magma Grunts there and helped Steven to defeat Maxie once and for all.
Afterwards, I visited Steven, picked up Dive, taught Dive to Manderly (I already taught him Surf) and followed the Underwater Path until I caught up to Archie and Team Aqua at the Seafloor Cavern. I beat the Grunts and made my way to Archie. I beat him, but not before he woke Kyogre. I met with Steven on the surface and made my way to Sootopolois City where Groudon and Kyogre was wreaking havoc.
I met up with Wallace at the Cave of Origin and set off for the Sky Pillar. On the way, Ned learned Extrasensory and I used the Leaf Stone I got earlier to evolve him into Shiftry. I finally got to the Sky Pillar, trained up a bit (Manderly evolved into Walrein and I went back and forth from Pacifidlog Town)) and got to Rayquaza in time for him to put an end to Groudon's and Kyogre's rampage.
I healed up, took on Juan's Gym and Ned made short work of most of his Pokemon (Manderly took care of Kingdra). I healed up and saved the game.
Update 6
I made my way to Ever Grande City and Victory Road. I beat Wally easy in there and made my way to the Pokemon League. I trained up a bit more until all of my Pokemon were in and around Level 60 and and I finally took on the Elite 4.
My whole party beat Sydney.
Robb and Sansa beat Phoebe.
Ned and Arya (w/ Brick Break) beat Glacia.
Manderly soloed Drake.
Ned, Robb and Sansa took down Wallace.
I made the Hall of Fame.
Immediately after the game restarted from the end credits, I flew to Victory Road and trained all of my Pokemon up to level 70.
Afterwards, I flew to Fallarbor Town, made my way up to Meteor Falls, and found Steven. I fought Steven with my entire team (bar Bran) and I won without losing anyone. I am the King of Hoenn.
