Castlevania II English Re-translation (+Map)

Hack of Castlevania II: Simon’s Quest


This is an English re-Translation of Castlevania II: Simon’s Quest. In additon to translating the ROM, an in-game map is added, and the Japanese staff credits were re-added to the game. The patch is for the NES version.

The translation is based on the original Japanese text. According to the author, extensive research was performed on the meaning of the sometimes cryptic original Japanese text in the game, and special attention was paid to make sure that all the translated text makes sense and is understandable, without undermining the loyalty in translation to the original Japanese game.

Features include:

  • NTSC version (there is also a PAL option)
  • MMC1 chipset (there are also MMC3, MMC4, MMC5, UNROM and VRC6 options)
  • Added dialog in select locations - Small changes that will improve the game experience without changing the nature of the game.
  • Reintroduced some features that the English releases removed from the Japanese version - Includes the extended ending text, as well as Konami-style Start text on the power-on screen.
  • Map function - An in-game map is included. It helps understand the layout of the game world, and to know the name of whichever place the player currently is in. It compensates for the lack of actual game manual, which in the Japanese releases included a map. Press the select button to view the map in the game.
  • SRAM save function - Game can be saved at any time into internal battery-backed memory and loaded later.
  • Advanced password encryption - Passwords that are encrypted with extended functionality, can be decoded by the original (unhacked) versions of the game. The function expands the repertoire of passwords.
  • Language - English.

There is also a document that lists in detail all the dialog in the original English and Japanese versions of the game, explains their meaning, and takes educated guesses on why certain lines were translated the way they were:

Huge Improvement But Not Without A Few Quirks

Reviewed By: Eldrethor on 26 Feb 2018

Castlevania II is an example of a game that’s fun but had its share of annoyances that cut into the overall experience, This hack strives to correct a lot of those flaws, and while the overall finish is a bit rough in a few places, the numerous quality-of-life improvements are a welcome change over the current state of things in the original game.

The improved translations and dialog speeds are a refreshing change over the cryptic and slow-paced dialog in the original, streamlining the day and night transitions to no longer stop everything you’re doing makes for a much smoother experience, being able to save your game instead of writing down a password is a huge improvement, and the in-game map is also a welcome addition in lieu of a physical strategy guide or Nintendo Power magazine. The new cinematic opening is also a fun spectacle that really shows how much went into this hack.

The downside is that this hack isn’t without its flaws, and some do cause a bit of a problem at times. The new map option has the unfortunate side effect of causing any monsters on your screen to respawn, which means that if you kill a monster and stand in its spawning location when you open the map, you’re going to take a hit as soon as you leave it. That and the new opening cinematic, while stunning to watch, also comes with a bug in which the game goes to a black screen if you either watch it all the way through or hit Start at certain points, which can be circumvented via a hard reset but is a problem that should be buffed out.

One minor quirk is a link to the author’s website appearing on the title screen, which isn’t unacceptable, but is a bit jarring to see, since most consoles games generally don’t put web links on their title screens. It’s handy but I think I was expecting a simpler “Retranslated by Bisqwik” line.

Despite its quirks, it’s a solid 8/10 hack that brings so much to the table. It makes the game a much richer experience than the original without overhauling it in its entirety, but it’s hard to ignore the respawn bug that’s currently attached to the map, and the post-prologue black screen should be addressed for sake of a clean finish.
