This is a homebrew Sudoku game cartridge for SNES, programmed for fun as part of the March 2019 RetroChallenge (project log here). One of the very few, if not the only game to support the NTT Data Keypad, besides the original JRA PAT online horse race betting system. (more info on this here)

Features:

  • 4 Difficulty levels, 100 unique puzzles each. (Total of 400 puzzles!)
  • Simple Hint engine. Detects sole cell candidate, unique row candidate and unique column canditate.
  • Invalid entry detection.
  • Auto-solver (please use it after giving up)
  • Supports the NTT Data Keypad for direct number entry!
  • Also supports standard SNES controllers: Use L/R to cycle through valid values for a given cell

Also available in catridge format for PAL and NTSC systems! https://www.raphnet-tech.com/products/super_sudoku/index.php

The source-code is now available on github: https://github.com/raphnet/super_sudoku

Just downloaded, looking forward to trying it out.  Thanks!

Thank you, I hope you like it! Are you using it on real hardware with a NTT Data Keypad?

No, I wish!  I have a SNES, but emulation is convenient.  I'm also a little surprised more games didn't use the pad, seems like it had potential.  

I have a question:  Is there any way to change the background, either to stop the scrolling or just make it a solid color?  It's a little hard to play for any extended time because the scrolling background causes me eyestrain.  Is there a menu I maybe missed?  

There is no way to do this at the moment, but hold on, I'll try to make a new build. I think I'll simply stop the scrolling once the puzzle is displayed.

Thank you for responding!  I look forward to any further developments.

Hello,

The grid in version 1.1 has an opaque background and uses softer colors. As the scrolling background is no longer showing through, I decided to keep the scrolling (for now) but I also slowed it down in an attempt to make it less distracting.

What do you think?
