Default WinUAE 1.6.2 Beta 9

A new beta release of version 1.6.2 of this Amiga emulator for Windows is available. These are the changes.

Beta 9:
  • vsync automatic frequency switching is now optional ("autovsync")
  • 100Hz/120Hz supported in vsync automatic switching mode
  • "Disable powersaving features" is now "Disable screensaver" (when not active) Screensavers are always disabled when active. Programs shouldn't override "real" powersaving features anymore (and Vista and later will ignore these requests anyway)
  • 68020 CE mode all instructions now need at least 1 CPU cycle (1/4 bus cycle) to finish (+any slow chip/custom memory fetches), previously all instructions were instant when accessing fast ram. Better than nothing..
  • CPU frequency configuration added (CE-modes only). Fast RAM (and ROM) is always considered wait-state free, chip ram speed does not change. Pre-defined values use main clock as CPU clock source (=includes PAL/NTSC difference), manually typed frequency basically emulate CPU card that has separate CPU clock crystal. For example pre-defined "7MHz" is 7.093790.. if PAL mode) Not very useful in 68020 mode. yet. (see earlier beta change log for explanation)
  • copper woke up 1 line too late (and never woke up if waiting for line 255) if wait ended on NTSC long line (this was the real reason for NTSC jumping, b8 hack removed)
  • added "cycle_exact" configuration entry, quick way to switch CE on/off with uae-configuration
  • wrong/missing display sometimes in "too fast" CPU modes (b5)
Download it at the English Amiga Board. It'll be later available here.
