Cracking Nintendo Entertainment System (NES) for Shovel Knight Implementation
Shovel Knight: Redefining the 8-bit Era with a Modern Twist
Shovel Knight, hauntingly reminiscent of NES classics, but undeniably unique when delved into, was lovingly crafted with a dose of modern flair by the gang over at Yacht Club Games. The devs, instead of blindly emulating the NES, leaned towards creating a rose-tinted facsimile of an 8-bit adventure—one that would give us a glimpse into how an 8-bit game might feel and play in today's world.
Ever wondered if NES development continued through the ages? What would an 8-bit game look like if developed in today’s day and age? That was the intriguing thought stirring in the minds of the Yacht Club crew. They envisioned that the advancements made in cartridge technology would have allowed for the techniques displayed in Shovel Knight. Furthermore, they decided to discard any limitations hampering the gaming experience, such as sprite flickering (a classic yet garish visual issue on the NES), making the gameplay clean, simple, and reminiscent of the hallmarks of a great NES title.
The game runs natively on modern hardware, a stark difference from the NES. This revelation surprised some players wishing to relive the glory days by playing Shovel Knight on a homebrew NES flash cartridge. The reality, though, is that it's a complex game, boasting various hardware platforms and configurations. On the latest Nintendo platforms, Shovel Knight makes use of Nintendo's Miiverse and Streetpass functionality, third-party middleware like FMOD audio, and SDL controller support, among others.
Some of the modern upgrades included extending the viewable screen space, resulting in the 16:9 resolution display (or 5:3 on the 3DS). Shovel Knight, despite having a wider screen, retains its pixel resolution identical to the NES, ensuring the gameplay feel remains intact. The background parallax scrolling, a feature more characteristic of the SNES, was also intensified to provide an average of 5-6 layers of backgrounds to scroll by, lending it a more readable gameplay layer.
Compromises were made in adhering to the NES's limited color palette of 54 colors. The devs added a few extra colors to display gradients that fell short on the NES. However, sticking to the restricted color spectrum was a priority for them, as it preserved the game's distinct visual style. The beige cloak, deep red hue, dark purple details, and light brown face color were created to serve this purpose.
Innovations were also made in regards to sprite color limitations and simultaneous color palettes. Unlike sprites that were confined to four colors (or three colors + transparency) on the NES, Shovel Knight sprites were given four to five colors to work with, allowing for more detailed and colorful sprites. Gameplay design decisions were informed by the concept of sprite flickering, making the game poor in onscreen objects and limiting the use of particle effects.
All these creative choices combined result in a Shovel Knight that, while stepping out of the NES boundaries, still resonates the spirit of the 8-bit era with great success.
