Stella v3.0 Alpha 3 changelog:
- Added rewind to the debugger. This is only active inside the debugger *after* you´ve done a step/trace/frame/scanline advance. Up to 100 such actions are
currently buffered, but I´m looking into increasing this (and compressing the state info) for a future release. There´s a button to do the rewind, the ´Alt-r´ key
combo, and a prompt ´rewind´ command.
- Added ´Fixed Debug Colours´ option, which can be toggled with ´Alt-Comma´. This is similar to the functionality in the no$26k emulator. Right now, the
colours are only optimized for NTSC ROMs. Also, shared colour registers aren´t separated (so P0 and M0 are drawn in the same colour). These issues
will be addressed in a future release.
- Fixed bugs with enable/disable of graphical objects; sometimes the entire object wasn´t disabled.
- Fixed display and timing issues with ROMs that generate many more scanlines per frame than a real system can handle. This fixes slowdowns and
graphical trash in Q-Bert and the recent Playaround Adult ROM.
- Added support for 6K version of Supercharger ROMs (currently, only Cubis exists in this format).
- Added ´-joyallow4´ commandline argument and associated UI item. This allows all 4 directions to be used on a joystick (which is required for the Bumper Bash
ROM). Be careful, this can cause strange problems with other ROMs like Berzerk.
- Added ability to completely disable fullscreen mode. The ´-fullscreen´ commandline argument (and associated UI item) is no longer a boolean, but has three
possible values (1/0/-1 for on/off/disabled).
- Changed NUSIZx descriptions in the debugger to be much clearer.
