Part 2: Track IDs
Updated list compiled by @budadeth and @cyanfire 
 
All you gotta do is name the music file after the track ID that it's supposed to replace. (example: vermillion city is 313, so if you want to have All Star by smash Mouth play in verm, you have to name it 313.mp3)
And then drop it in the folder of its corresponding region.
 
If an ID is missing from this list, it is also possible to type the command /bgm while in the game, to get the ID of the track currently playing.
If you do this, please post in this thread so the missing ID can be documented.

Part 3: Loops
 
If you paste in a track, it will just play from beginning to end and then start over.
If you want to say, play the intro of the battle theme, and then loop from after the intro onwards, you'll need these meta messages.
However, they currently only work with MIDI files.
There's already a very detailed guide on how to accomplish this, so I will just share it here.

Hello. My name is Isabelle. I'm returning to this game because I heard gen 5 was introduced, and a lot of my favorite pokémon come from gen 5 and 4 such as Whimsicott Roserade Chandelure and Jellicent. I have a decent amount of free time to no-life this game, so maybe I can get to the endgame bits such as completing the pokédex and building competitive teams. I hope to see some new and old faces!

It wasn't easy, but, I did beat them all with a team of 6x0 neutral or harming nature pokemon from the storyline, it was costly sure, especially the elite 4, but it is doable.  If I can pull it off anyone out there should be able to.  Except maybe @Tranzmaster, I hear hes pretty bad,

Cause e4 is basicly end of the storyline. Why do u expect it to be easy? Staff want player to stay in game after finishing it. If they will set goals harder to achive as a part of story which is considered as tutorial people will not feel this huge difference when they enter competive area.

Use a Curselax.

I 100% agree. The storyline is hard as fuck. I had to use my OP comps like Ttar, Dragonite and such to beat them. If you are just playing for storyline its almost impossible to beat it.
 
Also revive's cost 3k???? xdxdxd

With comps is easily doable, tho I 100% don't know how they expect a new player to beat the storyline legitimately.

The price of healing items should be brought down a bit. It's ridiculous that I have to get anxiety to use a healing item in a battle just because I may experience a net loss by the end of the battle.

shiny stone = sandile
dusk stone = littwick
 
dont know where dawn stones are found yet tho.

Theres two kinds of people; those who dont mind sharing those information, because they dont mind sharing and / or have no interest in ripping people off and then theres those who dont want you to know, so they can sell those stones for absurd prices, altough they´re filthy rich already.

I think the idea is "harder PvE battles", so you actually have to use smart moves, type advantages and maybe items, rather than two-shot everyone.
I don't really think there are many other reasons for it. If there are, they are more minor.

dude if you want a easy game, play tick tac toe, it's more for you probably. The game itself is already ridiculously easy to beat, you have access to 3 regions, you're not bound to clear a region with pokemons from said region, use your imagination. Did you ever reach end game in any mmo in 2 hours? Let me give you an example, I was an avid GW2 player, took me 3 months to craft a legendary weapon. 3 months. IF there are people who do the entire story not using a single comp pokemon, so can you. Stop being lazy.

You do not need to spend if you train, I particularly pass the story without spending anything, obviously you'll take a little longer, but it's possible.

I like the obedience caps. Like before if your mon goes over the cap u couldn't use it. Now it'll stay on the cap till next badge which is cool. It's better this way cause you basically go out with a team instead of a fcking over leveled God mon from the previous regions. Made the gamplay fair for everyone imo.

super cute i love it

Update: 
Due to the recent update, I've had to completely rework this guide. NPC rematch payouts were nerfed so I've went through and rematched everyone again in order to get the new payout totals. Sorry it took me this long, but I wanted to finish Unova and get all the dex entries for the new mons first lol.
 
Previously, rematching all possible NPCs (NOT including Swimmers, Tubers, and E4) would net you around 975k. Now however, it will only net you around 665k. And that INCLUDES the new Kanto gym rematches. It took me nearly 12 hours to complete. Granted I was stopping to type up NPC names and totals and ofc took a few breaks but still. 665k most definitely wasn't worth that much time.
 
Additionally, my custom "Quick Run" use to result in 365k in a little less than 2 hours. Now it results in 333k. (That's with Kanto gyms added as well so it takes longer now for less cash than before.) So yes, bit of a nerf, but nothing major. I dunno how efficient it is anymore to rematch for cash. It comes down to personal preference I suppose. I will probably still do my quick run since I'm not big on relying on GTL sales because might get bad RNG while farming, stuff might not sell, might get undercut etc. I always liked having 100% reliable income thru rematches. Probably only gym runs would be the best route for anyone interested in it casually. 168k is the total from all gyms combined.
 
Nonetheless, I still got the new payout data for every NPC if anyone wanted it. It's in the OP.

Oh and the spanish translation of this is currently the old version before the nerfs so you'll have to wait for @NagaHex to update his translation if you want accurate data there. 
 

All data is up-to-date as of the August 2018 Update. I will update accordingly if/when nerfs or buffs happen.
Update Log FAQs

Welcome! This is that guide where everytime the devs change the payouts I want to die a little as I have to rebattle HUNDREDS of NPC trainers for the nth time. Originally I made this guide when it was extremely profitable to rematch NPCs for cash but nerfs have happened so that's unfortunate, but it's still a decent income. 
 
Data Collected
This is EVERY re-matchable NPC in the entire game across 3 regions. (minus the Elite Fours) Swimmers and tubers are NOT included though because they're poor and not worth it. Payouts differ slightly each time you re-battle an NPC. Example: Might pay 3,700 one time, but 3,820 another. These totals were gotten while using the AMULET COIN while REMATCHING after defeating all E4s. These are NOT the totals you'll get from battling 1st time or early game rematching. KANTO
TOTAL CASH = $ 341,744
SEVII ISLES
TOTAL CASH = $ 93,580
HOENN
TOTAL CASH = $ 229,265
UNOVA
TOTAL CASH = $ 681,390
But, obviously, not all trainers are worth battling. So I made this custom money run in the section below to help players efficiently farm money from trainer rematches in a reasonable amount of time. Money totals have been rounded up/down for a cleaner look and easier maths. Hope you enjoy!
 
Custom Money Run The most profitable trainers to hit for the time spent! 
This run makes 420k in 2-3 hours. It's basically just the trainers that give 3.2k or more (and aren't too outta the way), plus the gyms.

The nerf to these leaders was unintentional, it should be resolved in the latest update

I've got some bad news @Eggplant, tile modes aren't supported on new client yet.

Fixed untradeable evolution stones not invoking evolution properly Fixed incorrect 'Unobtainable' entries in the Dex Fixed a non-functional patch of grass south of Dragonspiral Tower Fixed French B/W ROMs not reading region names correctly Fixed several incorrect item descriptions Fixed an issue where players could become stuck in Sootopolis Gym due to lag compensation

Look man, a game, and more specifically an mmo, needs factors that grab the players' attention and thus allowing them to immerse themselves in said game in a fun way. What you want is to simply spam the same things over and over again. Maybe that's fun for you but it certainly isn't for everyone. Players play a game to have fun, not to do chores. As Kyu said, they want you to explore the new stuff they worked hard for, and who knows? Maybe you could find a better farming spot that's more efficient and has better gain. People sometimes need to adapt or they get left behind.
 
Fate leads the willing, and drags along the reluctant.

Nothing is permanent, please remember.
 
If becomes too much of a grind they'll notice and patch accordingly, note that they want this to be sucessfull as much as we do.

sometimes you have to sacrifice yourself for the greater good
