Amiga emulator for macOS: vAmiga V3.0b1
Starting with version 2.6.1, developer Dirk Hoffmann made changes to the internal architecture of his Amiga emulator vAmiga for MacOS with the aim of porting the new emulator architecture of VirtualC64 v5.0 to vAmiga in order to enable features such as Run-Ahead (background article). Now he has released the first beta version of version 3, which introduces this feature. He writes about it:
"When run-ahead is enabled, two emulator instances run side by side: the primary instance and the run-ahead instance. The primary instance emulates the Amiga as usual, while the run-ahead instance runs several frames ahead and generates the image texture. Both emulator instances stay in sync with a time delay, and any changes in the primary instance, e.g., triggered by a joystick event, forces the run-ahead instance to be recreated. Run-ahead mode is meant for gaming as it considerably decreases the lag between an external event, e.g., a gamepad or keyboard event, and its recognition inside the emulator.
Accommodating this feature required significant changes to vAmiga’s architecture, resulting in a major update to the codebase. While these improvements have streamlined the internal workings of the emulator, they’ve also introduced some bugs - an expected outcome with such a substantial change."
The author therefore asks for feedback in this regard. He has also implemented the following improvements, among others:
- Snapshot compression
- Loading and saving memory contents
- Improved Headless app
- RetroShell as as serial port device
- Beamtrap debug feature
- RetroShell commands via the command line
The minimum system requirement for its emulator is macOS 11.0. (dr)
