40 sound effects created using FamiTracker.

Most of the sounds are suitable for a NES-style 2D Metroidvania game but can be used for platformers or whatever genre of retro game being produced.

All of the sounds are available to you royalty-free, they can be used in a personal project or game jam, but if you use them commercially, I would appreciate credit (for example: Sound Effects by Lazy Nerd 204) especially for games that have themes that reference autism or neurodiversity.
