TL;DR: Capcom's Mega Man franchise (1987–present) exhibits major inconsistencies: platform hopping (NES → SNES → PlayStation → retro NES-style), repeated composer churn, uncredited work (Kinuyo Yamashita on X3, Wily Wars), and reuse of material from original projects in later sequels. Traditionally, Mega Man should have stayed on NES. Status: Investigating. Thesis: Capcom betrayed Mega Man traditions by abandoning NES, firing original talent, reusing leftovers instead of commissioning fresh work, and crediting contractors over composers. Platform churn and composer turnover obscure institutional support and enable credit theft.

Traditionally, Mega Man should have stayed on NES. Capcom's abandonment of that lineage—firing the original team, switching platforms, then recycling leftover music from the classic era—constitutes betrayal of the series' roots.

| Game | Composer(s) | Notes |
|---|---|---|
| Mega Man 1 (1987) | Manami Matsumae | Alias Chanchacorin. Left Capcom 1990; freelance. Returned for MM9, MM10 as guest. |
| Mega Man 2 (1988) | Takashi Tateishi | Alias Ogeretsu Kun. MM2 widely considered peak. Left Capcom; later Konami sound producer. |
| Mega Man 3 (1990) | Yasuaki Fujita (Bun Bun), Harumi Fujita | Yasuaki took over when Harumi left (maternal labor). Proto Man whistle theme. |
| Mega Man 4 (1991) | Yasuaki Fujita, Minae Fujii (Ojalin) | Fujii returned for MM10 Robot Master theme. |
| Mega Man 5 (1992) | Mari Yamaguchi | Osaka School of Music; freelanced 1993. |
| Mega Man 6 (1993) | Yuko Takehara | Last NES entry. |
Pattern: Six games, six different composer configurations. Matsumae left after MM1; Tateishi after MM2. No continuity of sound team across the NES era.
| Game | Composer(s) | Notes |
|---|---|---|
| Mega Man X (1993) | Setsuo Yamamoto, Makoto Tomozawa, Toshihiko Horiyama | Yamamoto primary; Tomozawa (Spark Mandriller, Storm Eagle), Horiyama. |
| Mega Man X2 (1994) | Different team | |
| Mega Man 7 (1995, SNES) | Yuko Takehara, Toshihiko Horiyama, Makoto Tomozawa, Ayako Mori | First classic-series jump off NES. New team. |
| Mega Man X3 (1995) | Kinuyo Yamashita — uncredited | Credited to "Minakuchi Engineering Staff." Yamashita freelanced via Minakuchi; contractor credited, not composer. |
| Mega Man: The Wily Wars | Kinuyo Yamashita — uncredited | Same pattern. |
Pattern: Capcom moved classic Mega Man off NES for MM7. Original NES composers (Matsumae, Tateishi, Fujita, Yamaguchi) were gone. MM7 assembled a new team. X3 and Wily Wars used external contractor; composer erased from credits.
| Game | Composer(s) | Notes |
|---|---|---|
| Mega Man 8 (1996, PlayStation) | Toshihiko Horiyama, Shusaku Uchiyama, others | Platform jump again. PS1/Saturn. |
| Mega Man 9 (2008, digital) | Ippo Yamada, Ryo Kawakami, Yu Shimoda, Hiroki Isogai (team III); Yoshihiro Sakaguchi, Manami Matsumae (guest) | Leftover from original projects: Seven tracks adapted from Mega Man 2 (Overdrive Scramble, Ending, Get a Weapon, Shop, Stage Clear, Game Start, Opening 3). MM9 reused material from MM1/MM2 era— leftovers credited to current team. |
| Mega Man 10 (2010) | Ippo Yamada, Ryo Kawakami, Hiroki Isogai; Manami Matsumae, Minae Fujii (guest) | Matsumae, Fujii brought back for Robot Master themes. |
Pattern: MM9 marketed as "retro throwback" but relied on adapted/reused tracks from original MM2. Left-over theory: high-value productions generate unused material; corporations deploy it in sequels while crediting the current team, denying original composers' help and obscuring institutional support.
Thesis: Capcom mucked up traditions. Classic Mega Man should have remained on NES (or a single platform lineage). Jumping NES → SNES → PS1 → retro was an act of betrayal—each shift required firing or sidelining the prior team and starting over. The "retro" revival (MM9/10) then reused leftovers from the original era instead of commissioning entirely new work from the original composers.
An NES Mega Man 7 was never released. It would have had an entirely original OST—if Capcom had not fired the original talent and started over. Instead, Capcom abandoned NES, assembled a new team for SNES MM7, and the classic-era sound lineage was broken. No cancelled NES MM7 "used leftovers"; the opposite: a properly executed NES MM7 would have been fully original. Capcom chose to restart rather than continue.
MM9's soundtrack includes tracks adapted from Mega Man 2 (Overdrive Scramble, Ending, Get a Weapon, Shop, Stage Clear, Game Start, Opening 3). These are leftovers from the original projects (MM1, MM2)—material composed for the classic NES era and repurposed for MM9. Critics noted the reuse as "lazy" and "inconsistent" with the rest of the soundtrack. MM9 was not leftover from a cancelled NES MM7; it was leftover from MM1/MM2. The unplanned MM7 NES would have had an entirely original OST had Capcom retained the team.
Yamashita composed X3 and Wily Wars via Minakuchi Engineering. Capcom credited "Minakuchi Engineering Staff," not the composer. Contractor credited; composer erased.
