Ok:
-Pokecommunity didn't complete all new Gen V icons, so I found a link for you:
https://drive.google.com/drive/mobile/folders/1xxOEbLr1mD-RDqWS9g1t7bOas-QeUrGE?usp=drive_open
-I guess your Emerald hack will have 85-90% of pokemon that have second frame sprites in the first release version, right? and is it hard for you to create some custom second frame sprites for some pokemon that don't have it yet?
-I prefer the design of Pokemon & stats menu to stay originally as it is instead of HGSS and/or BW styles (like in Radical Red, Theta Emerald Renev & maybe Unbound), and for pokedex, well maybe a new PokedexPlus from this site but with Emerald design, but it's up to you.
-Are May & Brendan's pokemon teams different (aside from starters)?
-Does it have a rival battle inside the Pokemon League before battling the E4? (Like Barry/Sinnoh rival battle in the Pokemon League (DPPt))
-Does Scott from Battle Frontier have some battles in this hack to demonstrate players?
-I know it's obvious, but I want to say that I'm sure that in this hack, trainers in the Victory Road have mega evolutions like in EXWY, RRSS, & PSPM.
-Does this game have Medal challenges like in B2W2, or maybe a challenge like this in Pokenav?
-Will there be some mirage spots/places like in ORAS, maybe with some legendary encounters?
-Will there be some Item/Money sidequests like in Alola games?
-Does Safari Zone have 6 areas before E4/Post-game, or still 4 areas?
-I hope we can revive prehistoric pokemon by giving fossil items, instead of catching them as wild pokemon (Theta Emerald Renev).
-I wonder if you can add some new trick house puzzles.
-Is Soothe Bell available earlier in the game so we can evolve Pokemon that requires friendship easier, and because to evolve it, it takes a long time in Gen 2 & 3, longer than the next generations.
-What was your hardest part when your were working on your Emerald hack, and what will be the hardest part when you'll be working for some next versions?
-Before the release of ORAS, fans were listening to RSE soundtrack with some excitements, this year (or these days), I'm doing it the same but for your Emerald hack, listening to some Hoenn songs before playing the first version, or the version with Gen 8 Pokemon. (Crazy, I know ^_^)
-Are you working on your hack too much, or are you working on it sometimes and have some important and free moments like work, other hobbies, family & friends, going out...etc ?
Too many questions, I know, if you can't respond to all of what I wrote, that's okay.
