features

• implemented MIF 85 music interface
• sound driver enhanced to stereo
• command line arguments (full description here)
• configuration and command line option to use software renderer instead of accelerated
• trace messages enabled by default

bugfixes

• reduced lags and cracks in sound driver

GPMD85Emulator v0.10.1801 beta

screen rendering:

• upgraded SDL library to version 2.x and simplified screen rendering
• dropped custom OpenGL hacks (SDL2 is internally driven by OpenGL)
• massive refactoring of screen and user interface processing and rendering
• implemented custom surface blitter to fix an icons in the status bar
• scalers replaced with scanliner texture overlays
• every byte stored into VRAM memspace is projecting into union rectangle
• screen redraw will trigger only if union rectangle isn't empty
• fixed menu and keyhandling issues after migration to SDL2
• fixed critical issues with window/renderer/screen (re)initialization
• fixed x4 scale-function illegal memory access

emulation core:

• latest improvements into i8080 emulation
• implemented 256k memory expansion!
• all new memory features introduced into menu
• fixed updir-path related bug (deadloop) in file-browsers
• stripping of long filenames right on file-browser items in menu
• ChipMemory init splitted into separate child classes appropriate to each model
• PMD 32 emulation never depends on ROM file (because it was emulated by control commands) so all references to PMD 32 ROM file removed

bugfixes:

• fixed labels/shortcuts in menu 'FILE'
• added warning about wrong file extension for ROM modules
• fix disk image saving problems
• fixed cracking in sound output when sound driver processing for the first time
• fixed missing callback on some menu entries
• fix for narrowing conversion, unused variable in unfinished debugger

configuration:

• Booter2 for PMD 85-2A ROM module updated to latest version
• configuration changed, Booter2 will be default ROM module for model 2A
• default settings updated to version 3, extended to all new features
• rom directory slimmed down by removing of obsolete or unusable roms
• app will store own window position

GPMD85emulator v0.9.1402 beta

• fixed ANI/ANA instruction (result of AC flag)

GPMD85emulator v0.9.1206 beta

• optional OpenGL screen rendering (less CPU load)
• fast search in file-browser dialogs (thanks to @mikezt)
