The primary hurdle for the Switch version was the inherent power disparity between the hybrid console and its more powerful counterparts, the PlayStation 4 and PC. Bloodstained was built on Unreal Engine 4, an engine that requires meticulous optimization to run smoothly on the Switch's mobile-focused hardware. At launch, players encountered frequent crashes and a "muddy" visual quality that obscured the intricate character designs and atmospheric environments. The community's response was a mix of disappointment and a demand for better performance, leading the developers at ArtPlay and WayForward to dedicate months to rebuilding the game’s rendering pipeline specifically for the Switch.

: Introduced further performance tweaks and content updates. Version 1.6

Early Bloodstained NSPs had regional quirks (e.g., Japanese NSPs missing English voices). A "fully patched" NSP usually includes a fix to unlock all languages and the “Curse of the Moon” bonus content.

Patches moved the game from a blurry sub-720p to a much sharper image.
