For this release: SPC7110 emulation speed has been greatly optimized, massive improvements to HDMA timing have been implemented, Multitap support was added, and the user interface was polished a bit more.
Changelog:
- SPC7110 decompression code updated to latest version by neviksti and converted to a state machine; SPC7110 overhead is now identical to S-DD1 overhead (eg ~5% speed hit over standard games)
- Fixed a major bug in SPC7110 data port emulation that was crashing Super Power League 4 [Jonas Quinn]
- HDMA trigger point corrected to H=1104, bus sync timing corrected
- All illegal DMA A-bus accesses should now be properly blocked
- DMA state machine rewritten, greatly simplified
- Major corrections to HDMA run timing; fixes flickering bugs in Mecarobot Golf and Super Mario Kart
- Emulator now defaults to 2/1/3 SNES (CPU/PPU1/PPU2 revision numbers)
- Multitap emulation added, can be attached to either or both controller ports; user interface updated to reflect this
- Status messages (cartridge loaded / unloaded, UPS patch applied, etc) now appear in status bar
- Added advanced configuration option, "input.analog_axis_resistance", to control gamepad analog stick sensitivity
Also, the SPC7110 emulator download link below was removed: if you are looking for this, please download the bsnes v034 source code, which has the most up-to-date version in the src/chip/spc7110 folder.

|
|
General:
|
|
========
|
|
|
|
bsnes is a Super Nintendo / Super Famicom emulator that began on
|
|
October 14th, 2004.
|
|
|
|
The latest version can be downloaded from:
|
|
http://byuu.org/
|
|
|
|
Please see license.txt for important licensing information.
|
|
|
|
==============
|
|
Configuration:
|
|
==============
|
|
|
|
bsnes has two configuration files: bsnes.cfg, for program settings; and
|
|
locale.cfg, for localization.
|
|
|
|
For each file, bsnes will start by looking inside the same folder where the
|
|
bsnes executable is located. If said file is not found, it will then check your
|
|
user profile folder. On Windows, this is located at "%APPDATA%/.bsnes". On all
|
|
other operating systems, this is located at "~/.bsnes". If said file is still
|
|
not found, it will automatically be created in your user profile folder.
|
|
|
|
If you wish to use bsnes in single-user mode, be sure that both files exist
|
|
inside the same folder as the bsnes executable. If they do not, you can simply
|
|
create new blank files and bsnes will use them in the future.
|
|
|
|
If you wish to use bsnes in multi-user mode, simply delete these two files from
|
|
the bsnes executable directory if they exist.
|
|
|
|
If you wish to have multiple configuration profiles for the same user, you will
|
|
need to make copies of the bsnes executable, and use each one in single-user
|
|
mode.

Known Limitations:
|
|
==================
|
|
|
|
S-CPU
|
|
- Multiply / divide register delays not implemented
|
|
- "Glitch" when reading joypad registers during auto polling not implemented
|
|
|
|
S-PPU
|
|
- Uses scanline-based renderer. This is very inaccurate, but few (if any)
|
|
games rely on mid-scanline writes to function correctly
|
|
- Does not support FirstSprite+Y priority
|
|
- OAM / CGRAM accesses during active display not supported correctly
|
|
- RTO flags are not calculated on frames that are skipped when frameskipping
|
|
is enabled. This provides a major speedup, however it will cause in issues
|
|
in games that test these flags, eg the SNES Test Program Electronics Test.
|
|
Turning frameskipping off will allow RTO flag calculation on every frame
|
|
|
|
Hardware Bugs
|
|
- S-CPU.r1 HDMA crashing bug not emulated
|
|
- S-CPU<>S-SMP communication bus conflicts not emulated
