cv2r - Castlevania II: Simon's Quest Randomizer by BloodSweatAndCode. Come find me and the CV2R crew for chat on gameplay, racing, and development in the Discord!

Also, you can skip this repository entirely if you just want to generate a seed and play by going to the CV2R Website.

supported platforms

• NES console
• NT Mini
• fceux
• mesen

platforms with known issues

• bizhawk
  • There is bizhawk bug that causes a crash on the "game start" screen after a few seconds when using the QuickNes core. If you press start before the crash, gameplay will continue normally. You can avoid the crash entirely by using the NesHawk core, but your seed icons will still be glitched.

Difficulties

  easy                               The easiest mode for CV2R. Lots of hearts, reduced penalties, and a little more sanity
                                     around the enemization. A good place to start for brand new players.
                                     PATCHES: double-hearts, 100-hearts, lazy-river, penalty-reduction

  standard                           The most common way to run CV2R. Some heart buffs to keep the game moving, but that's
                                     all the help you'll get. Merchant prices and enemy HP are randomized.
                                     PATCHES: enemy-hp, 100-hearts, penalty-reduction, price-rando

  hard                               Ready for a challenge? No help with your heart grinds. Merchant prices and enemy HP
                                     randomized.
                                     PATCHES: enemy-hp, price-rando

  simons-quest                       Default Simon's Quest palette

Developer Flags

  --dev-force-enemy <devForceEnemy>  Spawn only one type of enemy, specified as "enemyId:tableId". For example, spawning
                                     only harpies would be "--dev-force-enemy 0x3B:0x7". Values for enemy and table id can
                                     be found in lib/object.js.

install

I plan to make executables so this installation isn't necessary, but until then, follow these steps:

1. Install node.js
2. Download the latest build of cv2r
3. Extract cv2r to a folder
4. Copy a vanilla cv2 rom into the cv2r folder as "cv2.nes"
5. In a command prompt:

cd /path/to/cv2r
npm install

# on Windows, "BSAC" is replaced by your seed (any string)
node --no-warnings .\bin\cv2r --seed BSAC cv2.nes

# on Mac/Linux (I've done ZERO Linux testing), "BSAC" is replaced by your seed (any string)
./bin/cv2r --seed BSAC cv2.nes

You can now find your new cv2 rando rom in the /path/to/cv2r/output folder
