Binary release v0.80.1 07/07/2024

New binary release for yapeSDL, the most notable novelty is comprehensive support for the Commodore VIC-20. Henceforth, yapeSDL supports emulating all three major 8-bit Commodore models in a single binary.

Overall

• 1-bit format and drag'n'drop support for WAV files
• remember last joystick keyset setting
• paste from clipboard with Alt+V
• cycle counter in external monitor
• VS2022, Mac/XCode & Linux compilation fixes
• serial IEC EOI improvement
• CPU halt bug fixed
• VIA improvements

Commodore plus/4

• TED sound fixes
• improved reading from open address space

Commodore VIC/20

• NEW! Commodore VIC/20 emulation with a rather decent compatibility

Binary release 0.71.2 21 Feb 2024

After a few years, finally a new binary (v0.71.2). The most important changes are as follows:

Overall

• SID (card) paddle support
• Optimized (unrolled) SID emulation core
• Added native un-ZIP support (via Minizip)
• Support for loading compressed TAP files
• Minor CPU regression for SHY fixed
• More robust error handling on startup in Emscripten builds
• Fixed transmitting of last byte after an EOI in IEC mode

Commodore plus/4 mode

• Implement Hannes 256 kb memory expansions
• ROM banking fix
• Unmapped memory read fix

Commodore 64 mode

• Somewhat improved VICII core (sprite, badline)
• Implement REU (256/512 kB)

UI changes

• Snapshot save menu item added
• Added menu item for attaching ROM images
• Added distinct soft reset and hard reset
• Fixed tape play/stop in the menu
• Better menu navigation with game controllers
• Lock Fn keys when run in a browser
• Fixed loading files of a relative path from the command line

External monitor improvements

• compare memory with command 'C'
• potential deadlock fixed on certain unices but there are still known issues with the monitor not functioning properly there

A binary for Mac is also provided with proper icon and signature. The emulator runs fine in a browser as well when compiled to Javascript using Emscripten. A working demo is available at http://gaia.atilia.eu/download/wip/YapeSDL.html.

YapeSDL (0.70.2)

The following changes were made since 0.70.1:

External monitor improvements:

• debuggable drive
• dump raster counters for Commodore 64 as well
• split functionality of the 'M' and '>' TEDMON commands
• hunt command ('H')
• repeating the last command on ENTER

Video:

• CRT emulation fix
• vsync option added
• adjust saturation & brightness
• hue offset option added
• CRT gamma correction added

Audio:

• better timing during frequent updates

Commodore plus/4 mode:

• TED emulation improvements ($FF1E writes, sound)

Commodore 64 mode:

• replaced palette with measured hues
• sprite emulation fixes
• improved serial IEC port emulation accuracy
• preliminary cartridge (.CRT) support

Overall:

• reduced static array initialization usage to reduce binary size for Emscripten
• isolated CIA emulation code
• various bug and compiler warning fixes
