SAE v0.7.0 Changelog:
*Common
- Chaned the project-name from 'Janus' to 'SAE' (Scripted Amiga Emulator).
- This step is necessary because i did'nt enough research before the initial release.
- There is already a project with that name in it. (janus-uae) I'm sorry for that, that was kinda stupid :)
- Separated the GUI form the core and rewrote most of it.
- Simplified the whole code. This means, that functions are called faster.
- Ported new Copper-, Blitter-, Audio-, Disk- and event-handling code from WinUAE 2.5. 0
- Moved all "beam-functions" to events.js, for faster access.
- Added "CPU-usage" to the GUI.
- Added "Hall of Fame".
*CPU
- Added support for exact cycling. The CPU have now 7.09 MHz on PAL and 7.16 MHz on NTSC resp.
- Added option for "Original"- and "Maximum"-speed.
*Audio
- Added a ring-buffer before output. No more "bagpipe"-like audio.
- Added a option to just emulate the hardware, but not to play any sound, e.g. "Agony" was not starting, if audio was disabled.
*Display
- Switched from the RGB to the 565 texture-format-encoding in WebGL, which gives a little more speed.
- Added support and a option for 4x scaling.
- Fixed screen-draging in lo-/hires-modes.
- Added a option to disable the output. Can be used to better play music-demos.
*Disk
- Added support for different speed-modes.
- Added support for extended ADF-files.
- Enabled write support. (to memory)
*Input
- The F-keys does work normaly now, i.e F5 does'nt reload the emulator, backspace does'nt go to the last page, etc...
- Fixed bug in the joystick-emulation.
