What NEXXT is

NEXXT is a free Windows studio for creating graphics intended to follow NES display rules. It emulates the NES picture processing unit so creators can check graphics against those rules while working. Canvas tools support drag selection, moving, swapping, and cloning, with pixel and NES attribute grids. The maker documents importing a bitmap as a nametable with a chosen tile count and provides tools for creating and editing metasprites by placing and merging tile data. Canvas data can be exported as binary or as ASM and C header text, including nametable and attribute table information. Listed formats include PNG-8, PNG, BMP, CHR, NAM, and PAL. NEXXT also includes an animation timeline, indexed color tools, and tilemap tools. It continues Shiru’s NES Screen Tool and is described as portable. The linked nexxtporter command-line utility extracts CHR, nametable, and palette files from session files and can generate PNG bitmaps. NEXXT is public domain. The maker notes that cartridge hardware or clever programming can bend some emulated restrictions.
