• another new emulation level (VHA, very high accuracy)
• started implementing exact video shift register emulation in VHA mode
• improved PAL-NTSC switch artifacts
• oversampling now also for the SID card
• selectable sound replay frequency
• more fullscreen mode options
• added support for test mode
• bug in the FIR filter fixed
• TED border flipflop check was 1 cycle off
The new emulation level implements support for the emulation of the video shift register and also better support for demos that mess with the horizontal counter (about 3 of them exist at the moment). Since about 99.9% of the available programs don't require these to be emulated, it has never been a priority, as they do have a rather high performance hit (about 20 percent but your mileage may vary). The new mode is still experimental and therefore it may not work perfectly in all cases, so please report if you encounter problems. Most users won't have true benefits from this new mode, as it is mostly meant for demo coders or as means for watching the few available demos that require these to be emulated.
