HermIRES it’s a cross-platform hires bitmap (Art Studio 1 format) editor for the Commodore 64.

The format has some restrictions, here are the rules:

• The maximal resolution of the picture is 320×200
• Only 16 fix C64 colours can be used (no gradient either)
• In a 8×8 pixel-block only 2 colours can used to be displayable by C64 (this is detected in HermIRES, but .hbm files can be saved with clashes too.)
• On a real C64 the PAL will blur the screen-content a bit, should check on CRT, or at least VICE emulator’s CRT simulation.

Changelog:

Added:

• Color swapping fast-button – Tilde “`” button (BitBreaker’s idea)
• Show pen-diameter preview circle if diameter is bigger than the default
• *dense (pixel-scale) grid toggleable (in bigger magnifications too).
• *added ‘Deny painting’,'Reuse existing colour’ and ‘Set block colour’ mode to ClashTest – different settings on/off in case clash would happen…
• *showing zoomed area in the preview, allow going to area in zoomed mode when left-clicking on preview
• Showing ongoing progresses by text/graphics (loading/converting/drawing…)
• Selectable CRT emulation for Preview/Grid only… (for faster operation on slow machines)
• Undo step number displayed (should undo history also be saved?)

Fixed:

• Control/shift/alt stucked in Win7 with allegro devpak 4.2… -> using allegro devpak 4.4.2 version instead!
• Reduced overall CPU usage – refined timed and pixelling/detection events
• iI Windows it was slow (especially in CRT emulation) -> wrote optimized software CRT-emul.pixelling for GridDrawer, not relying on hw-acceleration
• *pressing F1..F4 fucked up (enlightens) toolbar sometimes – solution: timing stabilizer / thread safety check solved it
• Preview-zoom title-text was overwritten by Grid-Zoom-text in the smallest resolution mode with 2-digit magnifications
• *there was ‘allegro error #11′ and ‘segmentation fault’ at lower than required resolution – it was logical mistake in resolution-decider loop
• Made dithered and big-pendiameter filled rectangle/circle drawing faster (set the steps according to pen-diameter)
• *allegro filename-extension detection was wrong – if ‘.’ used in filename and no extension given, only the name before was saved to disk! -> used ustrcmp & strcat instead
• *C64-executable format name-tag (caption) now editable (deleting it disables it)
