HermIRES is a popular, cross-platform graphical editor used to create and modify high-resolution (hires) bitmaps specifically for the Commodore 64 (C64) vintage computer system. Developed by a prominent retro-scene programmer known as “Hermit,” the software allows modern PCs running Windows or Linux to design artwork that complies with the strict hardware limitations of the C64’s VIC-II graphics chip. System Restrictions & Capabilities
When using HermIRES, the canvas enforces the authentic limitations of a real Commodore 64 running in standard High-Resolution mode:
Resolution: The canvas is locked to a strict 320 × 200 pixel layout.
Color Palette: Artists can only use the official, fixed 16 C64 color palette with zero modern gradients.
The “Attribute Clash” Rule: Within every 8×8 pixel grid block, only 2 colors can be used simultaneously. HermIRES features built-in “Clash Testing” to identify when an artist accidentally attempts to use a third color in a single block. Core Features
Cross-Platform Portability: It is distributed via SourceForge as a lightweight package containing binaries for both Windows and Linux.
CRT Display Emulation: The software includes a toggleable CRT filter that simulates old-school television hardware. It replicates the horizontal scanlines and PAL signal color blurring to let artists see how their art will truly look on a vintage monitor.
Flexible Painting Tools: It features customizable brush diameters, symmetric pen shapes, color-swapping shortcuts, and localized zooming.
File Compatibility: It natively saves and edits files in the Art Studio 1 (.hbm) format, which can be transferred directly to real C64 hardware or run on modern PC emulators like VICE. HermIRES download | SourceForge.net
