Vectorman 2 - Intro A https://chiptune.app/?play=Sega%20Genesis%2FVectorman%202%2F...

Sonic 3 - Ice Cap Zone https://chiptune.app/?play=Sega%20Genesis%2FSonic%20the%20He...

I still listen to all of the following regularly. Castlevania IV and ActRaiser in particular have pretty incredible arrangement and sound design for being so early in the system's life.

From the Super NES:

  - Super Castlevania IV
  - ActRaiser
  - Axelay
  - StarFox
  - Gradius III
  - Teenage Mutant Ninja Turtles IV: Turtles In Time
  - U.N. Squadron
  - Final Fantasy VI (III in the US)

From the Genesis:

  - Sonic 2
  - Sonic 3 & Knuckles
  - Ranger-X

From the Unreal Tournament Soundtrack:

  08 - Botmca
  11 - Enigma
  17 - Skyward Fire
  28 - Foregone Destruction

Note: I think there's something up with chipplayer.js' tracker playback because some of these Unreal Tournament tracks were definitely playing slower than they should.

Lizardking’s stuff is great, e.g. Triton Theme: https://chiptune.app/?q=lizardking

Thunderforce III - Stage 1 / hydra on the Sega Genesis / Megadrive is probably one of mu favorite game music ever. But really the whole playlist is nice.

Also on the same console I like a lot of soundtracks from games that were ported from Amiga: Lemmings, Lotus, James Pond II, they all have some kind of cert different character to traditionnal consoles music.

Well...

GB

  - Pokemon crystal

SNES

  - Tales of Phantasia (It's probably top 5 in best OST for SNES)
  - Donkey Kong series
  - FF Series
  - Terranigma   Some good tracks, like:
    - Evergreen
    - Sanctuary
   - Earthbound (not recommended but I do enjoy some tracks)
    - In winters there is a genius
    - Heartless Hotel
    - Megaton Walk
     Some notes, Many of the tracks here are actually pop music, (Even the Beatles!), but its been mashed so much its indistinguishable. theres a nice youtube video about it.
   - Super Mario RPG (And my name bookie is fantastic)
   - Street Fighter 2
   - Kirby
   - Sim City    (City is just 5/5)
   - Anything Mario really     (Kart, Bros)
   - Spider man Maximum Carnage
   - Tetris Attack ("Forest stage" is super chill)
   - Uchuu Race Astro Go Go
   - Tetris & Dr mario (I've listened to this so much, I'm 
  unsure if its good)
  - Tiny Toon Adventures: Buster Busts loose (A little zany 
  but I like a few)
  - Zombies Ate My Neighbors
    Last but not least is ZAMN, which has one of the best tracks for the SNES, Mars needs cheerleaders (and also Pyramid of fear). It is genuinely good

I could make a bigger list, but I think after PS1 and N64 costs too much CPU and you're better off getting nonchiptune.

Some Mentions

  - Layton (DS)
  - Saga Frontier 2 (PS1)
  - dot hack (PS2)
  - Megaman Battle Network Series (GBA)

Its strange, you have to dredge through so much chiptune to find some tracks so recommendations list are always nice.

Ah yes, Donkey Kong Country, Mario, and Terranigma are already in my playlist. Thank you!

Thank you all for all the recommendations! Will listen through them when I have time. :D
