TM2 Converter

TM2 (TIM2) is a raster image format developed by Sony Computer Entertainment for the PlayStation 2 console, released in Japan on March 4, 2000, as the successor to the original PlayStation's TIM format. TM2 extends the TIM specification to accommodate the PS2's more capable Graphics Synthesizer (GS) GPU, supporting 4-bit indexed (16 colors), 8-bit indexed (256 colors), 16-bit direct color, 24-bit true color, and 32-bit true color with full 8-bit alpha transparency — a significant upgrade over TIM's single-bit semi-transparency flag. The TM2 container includes a file header with a picture count (supporting multiple images in a single file), individual picture headers specifying dimensions, color depth, mipmap count, and CLUT format, the CLUT data, and the image data arranged to match the GS's swizzled memory layout for optimal rendering performance. TM2 files support mipmaps (progressively smaller versions of a texture for distance-based level-of-detail rendering), a feature absent from the original TIM format, reflecting the PS2's ability to handle more sophisticated texture filtering. One advantage is the format's importance in game preservation: thousands of PS2 titles — the best-selling console generation in history — store their texture assets as TM2 files, making the format essential for game modding, texture extraction, HD remaster projects, and academic study of game art history. TM2 files are handled by specialized tools like Rainbow, noesis, and ImageMagick, as well as PlayStation 2 emulator debugging utilities.
