The game was later converted and published to Sega Master System (which is the version most people are familiar with) by Sega and to the Nintendo Entertainment System (which stayed in Japan) by Tokuma Shoten.
Captain Silver provides examples of:
- Adaptation Expansion:
- Sega Master System version cuts the final stage into two separate levels, with the pirate ship part fleshed out.
- NES version received even more expansion, including new purchasable spells at the shop.
- Antagonist Title: The titular Captain Silver is the Final Boss of the game.
- Fake Longevity: You have to play the whole game twice to see the ending.
- One-Hit-Point Wonder: A single blow is enough for Jim to send him back to the checkpoint.
- Platform Hell: Captain Silver rarely throws you a platforming section, but when it does, it's really dreadful. This is not so much for the platforming itself, but rather for its glitchy hit detection, which may decide you didn't step on the platform properly and make you fall through it.
- Rock Me, Amadeus!: The first stage's music interpolates two movements of Edvard Grieg's Peer Gynt suite: "Anitra's Dance" for the main BGM, and "In the Halls of the Mountain King" for the Pied Piper miniboss theme.
- Super Drowning Skills: Wasn't really notable case in the 1980s, but it's still hilarious because Jim can drown in a water fountain, of all places.
