Anciennement connu sous le nom de bsnes, il s’agit d’un émulateur de NES/SuperNES/GameBoy/GameBoy Color/GameBoy Advance/WonderSwan/WonderSwan Color/SwanCrystal, (et anciennement Nintendo DS) mais aussi les sous systèmes Super GameBoy, BS-X Satellaview et Sufami Turbo. En fait bsnes existe toujours mais n’est qu’un module de Higan (concernant la Super NES) tout comme bnes (non disponible séparément) avec la NES, bgb (non disponible séparément, et sans rapport avec BGB) pour la GameBoy N&B/Color, bgba (non disponible séparément) pour la GameBoy Advance et BWS pour la WonderSwan N&B/Color/Crystal. Il émule également toutes les puces d’améliorations supplémentaires: Super FX/FX2, CX4, DSP, SA-1 et beaucoup d’autres et se paye le luxe d’ajouter le module MSU-1 qui aurait pu être ce qu’aurait donné un SNES-CD si celui-ci avait été rendu public.
A présent, il n’y a plus qu’un seul binaire orienté sur la stabilité et l’absolu précision (il sert principalement aux développeurs ou à ceux qui cherchent une émulation Low Level de référence). A noter qu’un pack de shaders est disponible ici.
Les changements:
– SFC: balanced profile removed
– SFC: performance profile removed
– SFC: expansion port devices can now be changed during gameplay (atlhough you shouldn’t)
– SFC: fixed bug in SharpRTC leap year calculations
– SFC: emulated new research findings for the S-DD1 coprocessor
– SFC: fixed CPU emulation-mode wrapping bug with pei, [dp], [dp]+y instructions [AWJ]
– SFC: fixed Super Game Boy bug that caused the bottom tile-row to flicker in games
– GB: added MBC1M (multi-cart) mapper; icarus can’t detect these so manual manifests are needed for now
– GB: corrected return value when HuC3 unmapped RAM is read; fixes Robopon [endrift]
– GB: improved STAT IRQ emulation; fixes Altered Space, etc [endrift, gekkio]
– GB: partial emulation of DMG STAT write IRQ bug; fixes Legend of Zerd, Road Rash, etc
– nall: execute() fix, for some Linux platforms that had trouble detecting icarus
– nall: new BitField class; which allows for simplifying flag/register emulation in various cores
– ruby: added Windows WASAPI audio driver (experimental)
– ruby: remove attempts to call glSwapIntervalEXT (fixes crashing on some Linux systems)
– ui: timing settings panel removed
– video: restored saturation, gamma, luminance settings
– video: added new post-emulation sprite system; light gun cursors are now higher-resolution
– audio: new resampler (6th-order Butterworth biquad IIR); quite a bit faster than the old one
– audio: added optional basic reverb filter (for fun)
– higan: refresh video outside cooperative threads (workaround for shoddy code in AMD graphics drivers)
– higan: individual emulation cores no longer have unique names
– higan: really substantial code refactoring; 43% reduction in binary size
Note: The major change is that, as of v099, the SNES balanced and performance cores have been removed from higan. Basically, in addition to my five other emulation cores, these were too much of a burden to maintain. And they’ve come along as far as I was able to develop them. If you need to use these cores, please use these two from the v098 release.
I’m very well aware that ~80% of the people using higan for SNES emulation were using the two removed profiles. But they simply had to go. Hopefully in the future, we can compensate for their loss by increasing the performance of the accuracy core.
If you want to know more about the removal of these two profiles, please read this article for a more in-depth explanation.
