Castle Escape (SEGA Master System)

Wee Knight must escape the haunted castle collecting gold coins and dodging the castles deadly inhabitants as he goes. Due to the enormous weight of his armor, Wee Knight cannot jump very high unless he consumes the magenta eggs found within the castle. But beware, the anti-gravity effects of the eggs do not last long leaving Wee Knight at risk of missing out on the castles many treasures. Prolong life by collecting the hearts and don’t let Wee Knight fall too far or he'll be crushed by the weight of his own armor. |

interesting audio technique for the title song (basically a 1bit-pwm) | |

That's relatively common in modern ZX Spectrum homebrew, but pretty rare on SMS. |

Beeper music

The music is by Rich ‘Tufty’ Hollins. He has a couple of beeper albums out on the Speccy. Lookup ‘I Beeper Tufty’ or ‘On and Off Tufty’ on YouTube. He also does a lot of music for the Speccy home brew scene. I believe this is the first time it’s on the SMS. |

You could take a look at this: There is source code for various 1 bit beeper routines here: https://github.com/utz82/ZX-Spectrum-1-Bit-Routines |

I remember Tim Follin doing something like that on the Speccy when I was a kid. Agent X, I was amazed by it. | |

1tracker by Shiru is another tool. It’s interesting because he uses a scripting engine to generate Z80 source code which makes it possible to easily port over from the Speccy to the SMS. I’ve ported the phaser1 and phaser3 engines, there are many more. |

Castle Escape uses phaser1 for the title music and WYZTracker ported to the SMS for sound effects and game PSG music, and Chibiwave for the samples. |

Does any of the SMS ports of these audio engines are open source and available somewhere? It would be nice to have them in our selection of options :) |

Happy to share what I’ve done, but I need to do some cleanup. The below link is for Shiru’s 1tracker It has many beeper engines for the Speccy. Because he uses a scripting language it’s possible to add a new (or port existing) beeper engines without modifying the sources for the tracker. https://shiru.untergrund.net/software.shtml Here’s WYZTracker, I don’t have the SMS player integrated into the repo yet. https://github.com/iratahack/WYZTracker Here’s the Chibiwave stuff, looks like there’s already an SMS version, lol. https://www.chibiakumas.com/z80/platform4.php#LessonP38 IH. |
