ByteLoom Werx

Create, edit, animate, and export Atari-style 8×8 fonts, tilemaps, and POKEY music—all in one creative suite.

ByteLoom Werx includes an experimental NTSC artifact-color preview with selectable NTSC and monochrome display modes. It may not perfectly reproduce every Atari, television, or emulator configuration, but it provides a useful approximation of how artifact-colored graphics could appear.

Features:

• Edit complete 128-character, 8×8 bitmap fonts
• Load and save raw 1024-byte .FNT files
• Use four independent, animatable font banks
• Stop animation on any bank and continue editing
• Flip, shift, rotate, copy, cut, and paste characters
• Select multiple characters using a rubber band
• Preview pasted characters before placing them
• Create normal and inverse characters
• Merge four font banks into one 4096-byte file
• Build 40×24 tilemaps with pencil, eraser, line, box, and filled-box tools
• Select, move, copy, cut, and preview map regions
• Pick characters directly from the map with the eyedropper
• Show or hide tilemap grid lines
• Undo and redo font and map edits
• Export maps as .DAT files or PNG images
• Export fonts and maps as BASIC DATA
• Compose music with a multi-track piano roll
• Draw sustained or individual notes and audition chords while composing
• Create reusable instruments with envelopes, distortion, arpeggios, vibrato, slides, retriggering, and custom-drawn waveforms
• Preview POKEY-style instruments and music
• Import compatible SAP/RMT note data
• Export music with a relocatable background player for FastBasic
• Export selected font banks as FastBasic data with animation support
• Generate a FastBasic DrawMap procedure
• Combine fonts, animation, tilemap, music, instruments, and the background player into one ready-to-test FastBasic program

Some raw 8×8 fonts from other systems, including certain Commodore 64 fonts, may also load when their byte layout is compatible. ByteLoom Werx is primarily designed around Atari 8-bit graphics and sound—the system I grew up with and know best.
