bsnes v073 released - 模擬器

http://byuu.org/

This release marks a major step forward, offering full low-level emulation of
all four DSP coprocessors based on the NEC uPD77C25 processor core. Many
people were responsible for this milestone: Dr. Decapitator for the actual
decapping and extraction; Lord Nightmare for the cartridges and some special
analysis tools; myself, Jonas Quinn and Cydrak for the uPD77C25 emulation;
and all of the donors who raised the necessary $1,000 for the necessary
hardware and equipment needed to pull this all off. To say thanks to the
donors, I am releasing the uPD77C25 emulation core to the public domain, so
that everyone can benefit from it.

All four DSP emulations will be improved by this by way of having realistic
timing; the DSP-4 will benefit further as the high-level emulation was
incomplete and somewhat buggy; and the DSP-3 will benefit the most as the
high-levle emulation there was not complete enough to be playable. As a
result, most notably, this means bsnes v073 is the first emulator to fully be
able to play SD Gundam GX (J)!

As bsnes' primary goal is accuracy, the LLE DSP support renders the old HLE
DSP support obsolete. Ergo, I have removed the 166KB of HLE source code, and
replaced it with the uPD77C25 core, which comprises a mere 20KB of source
code. As this LLE module supports save states, this also means that for the
first time, DSP-3 and DSP-4 games have save state support.

On the other hand, this also means that to run any DSP game, you will need
the appropriate program ROM. As these are copyrighted, I cannot distribute
them nor tell you where to get them. All I can do is provide you with the
necessary filenames and hashes.
