SSE pour « Steven Seagal Edition » est un émulateur d’Atari ST basé sur le STeem original v3.2 de 2004. Il emprunte également des améliorations en provenance de Hatari.
Les améliorations sont les suivantes :
Features
– Can copy from the ‘readme’ texts to the clipboard.
– Can use Steem on a second monitor (D3D).
– Optional borderless window fullscreen mode for even more compatibility (D3D).
– ‘Laptop’ fullscreen mode renamed ‘Max Resolution’, now with correct aspect ratio + optional ST aspect ratio (DD).
– Sound: more sampling rates are managed, up to 384Khz. Higher rates depend on your hardware. They can reduce aliasing in some cases (Star Trek, Union Demo).
Emulation improvements
– Hardware Expansions: Support for MonSTer alt-RAM.
– Blitter:
*Further improvements of blit mode bus arbitration.
*Note that those improvements increase overhead while having no practical use (game, demo…), but that’s the price of more precise emulation.
*Thx Cyprian for good test programs.
– YM2149: If option’C2′ is checked, an alternative, lower level YM2149 emulation inspired by MAME is used. Thx Couriersud.
– Timings: NTSC clock for the Mega ST, PAL clock for the STF and the STE.
Refactoring
– Former options ‘Interpolated Scanlines’ and ‘PAL Aspect Ratio’ have been merged into a new option ‘ST Monitor’.
– MFP: Timer B tick better following the ‘DE’ signal.
*More precise timers when the CPU is accelerated (sound routines).
*Some timing changes.
– CPU: 64bit cycle timers (Win64). This makes older memory snapshots incompatible.
Bugfixes
– CPU timing destination = .W (-An).
– GUI crash on select MIDI in (Win64).
– DC offset: sound is now centred on zero, start/stop shouldn’t click.
Note: PSG emulation produces positive-only values, DMA sound samples are signed.
– 2.5MB memory setting was forgotten at second cold reset.
– More compatible, less trashy fullscreen GUI (DD & D3D).
– Some other Fullscreen bugs (trash, wrong size…).
