FNF B Sides looks like a simple palette swap of the original Friday Night Funkin’ demo, but it plays like a completely different rhythm challenge, because every chart underneath those new colors has been rebuilt from the ground up rather than just recolored.
How FNF B Sides Repaints the Original Weeks
The base idea is straightforward once you see it: take the original demo build of Friday Night Funkin’, keep the same week structure, and rework almost everything inside it — sprites, backgrounds, and especially the music, which gets full song remixes rather than simple pitch shifts or filters.
Boyfriend, Girlfriend, and the rest of the opponents all get new palettes as part of that overhaul, and in the mod’s original version that mostly meant color swaps — Boyfriend’s usual red and blue became pink and purple, for instance. It reads as a reskin at a glance, which is exactly why FNF B Sides catches people off guard the first time they actually sit down and play a chart instead of just watching a screenshot.
What doesn’t change is the underlying engine: four arrow keys, a scrolling note highway, and a health bar that swings toward whichever side is landing more hits. FNF B Sides isn’t reinventing that formula, it’s just proving how far new charts and a new coat of paint can stretch it.
Legacy Versus Redux: Two Different Versions
The mod has effectively existed in two eras. The original release, now referred to as Legacy or Classic, covered the base game’s first six weeks with the exception of Monster, adding up to eighteen remixed songs across that stretch.
About a year and a half later, the mod got a full overhaul called Redux, which didn’t just patch the old content — it replaced the color-swap approach with more original character designs and rebuilt the remixes to match the quality bar other remix mods had raised in the meantime. Redux’s initial release covered Weeks 1, 2, and 7 along with a dedicated Tutorial chart, folding in the rest of the Legacy content alongside it.
That split means two people can both say they’ve played FNF B Sides and be talking about noticeably different builds, depending on whether they first picked up the mod years ago or came to it after the Redux overhaul landed.
New Looks for Boyfriend, Girlfriend, Skid and Pump
Character redesigns are one of the clearer ways to tell Legacy and Redux apart. In Redux, Boyfriend keeps his role but gets a much more built-out look — longer pink hair, a purple cap with a red brim, a jacket over a purple shirt, and a pair of Soap shoes borrowed stylistically from platformer influences rather than just a straight recolor of his default outfit.
Skid and Pump get a simpler but instantly readable swap: their colors trade places, so Pump ends up white while Skid turns orange, on top of new hat and mask details for both. Senpai and Spirit get redesigned too, with Senpai wearing a white polo and yellow tie instead of his usual look, and Spirit rendered with a blue-hued palette in place of the original’s colors.
None of these redesigns are purely decorative — they also track which week’s chart got the Redux treatment first, so spotting a fully redesigned character versus a straightforward palette swap tells you roughly how recently that particular week was touched.
The Tracklist, From Bopeebo to Stress
Between Legacy and the ongoing Redux releases, the mod now spans remixed versions of songs from across the base game’s week structure:
- Bopeebo, Fresh, and Dad Battle from Week 1
- Spookeez and South from Week 2
- Pico, Philly Nice, and Blammed from Week 3
- Satin Panties, High, and M.I.L.F from Week 4
- Cocoa, Eggnog, and Winter Horrorland from Week 5
- Senpai, Roses, and Thorns from Week 6
- Ugh, Guns, and Stress from Week 7
Monster is the one notable gap, left out of the original Legacy set even though the rest of Week 2 got the remix treatment. The Week 7 tracks — Ugh, Guns, and Stress — came later as part of the Redux push, arriving as a set often labeled B-Side Redux in the mod’s own file names.
Hearing a familiar song like Bopeebo open the same way before twisting into a completely different arrangement is usually what convinces skeptical players that FNF B Sides is more than a simple reskin.
Why FNF B Sides Charts Hit Different
Because the songs are full remixes and not just retuned versions of the originals, the note charts built on top of them don’t map cleanly onto muscle memory from the base game. By the time a playthrough reaches Stress, the Week 7 track that arrived with the Redux overhaul, the jump in density compared to Week 1’s Bopeebo remix is hard to miss.
Players who’ve spent time with both versions tend to describe Redux as noticeably tougher than Legacy in the charting department, since the newer passes lean into denser patterns that match the more aggressive remix style rather than the gentler color-swap era’s charts.
That difficulty jump is also where the most common complaint about the mod shows up: because Redux rolled out week by week rather than all at once, players who want the full experience have had to wait for individual weeks to get their overhaul, and several of the original Legacy weeks are still waiting on their own Redux pass.
Awards, Downloads, and the Community Around B Sides Redux
FNF B Sides isn’t a niche curiosity within the mod scene — its page has racked up somewhere around 3 million views and 1.3 million downloads, numbers that put it among the more visible remix mods in circulation. It also won Best Remix Mod of the Year at the Gamebanana Mod Awards in 2022, which is generally treated as a meaningful stamp of approval within the modding community.
Fan content built around it hasn’t slowed down either. Spin-offs with names like a playable Girlfriend variant and various fan-made continuations of the Week 6 content circulate alongside the main mod, which is usually a sign that a fanbase outgrew the original release rather than losing interest in it.
None of that changes the core pitch, though: it’s still a remix project built on somebody else’s demo build, dressed up enough that newcomers sometimes need reminding that it started as fan content and not part of the base game’s official week lineup.
- Is FNF B Sides an official Friday Night Funkin’ release? No — it’s a fan-made mod that reworks the original demo build’s songs and character designs rather than an official expansion.
- Do you need to finish the base game’s weeks before trying B Sides? Not really, since the charts stand on their own, though recognizing songs like Bopeebo or Senpai underneath the remix does add to the experience.
- Which weeks got the Redux treatment first? Redux launched with Weeks 1, 2, and 7 plus a dedicated Tutorial chart, with the remaining Legacy weeks folded in as the overhaul continued.
FNF B Sides keeps pulling players back for a simple reason: a familiar intro like Bopeebo suddenly detours into unfamiliar territory, and the only way through is to relearn it note for note. That shock of recognition followed by a completely different chart repeats all the way through Stress, which is exactly why the mod still gets brought up years after Legacy first appeared in the community.
