The changelog for this release(Part 1):
Quote:
For this release we spent much time rewriting, porting, improving many internal
subsystems. ZSNES is a program with over 200,000 lines of source code and in this
release, over 25% of that has been modified. Also around 15% of assembly has been
ported to C. The upcoming list while large can't fully describe the amount of
work and the amount of improvements made. Make sure to see the readme to find out
how to use all the new features.
Subsystem Additions/Updates/Rewrites/Fixes/Improvements:
----------
- Ryan C. Gordon's ManyMouse support added. [Nach, pagefault]
This allows the systems compatible with ManyMouse ((Windows XP, Linux via
evdev if read permission set, Mac OS X) to handle each mouse plugged into
the system separately. So now games with two mice using devices can be played
with 2 player (or 1 player controlling both) on a single PC.
Left Handed Mouse Support. [Nach, Deathlike, Jonas Quinn]
So lefties can have the buttons for a particular mouse swapped if they so
desire.
- Rewrote directory handling system. [Nach, Jonas Quinn, grinvader, Deathlike]
The old system dubbed "ZFile" only kept track of files in a limited manner
allowing for many many bugs. The new system dubbed "ZPath" now tracks files
and paths in a clean systematic manner to eliminate all file/path related
bugs that have made previous versions annoying. All file handling code is
now done in C and has many functions to make it easier for anyone else to
jump right into this bit of development. This also allows for many new
features to be written, and we wrote quite a few. A debug system has also
been added making it easy to track file issues regardless of the operation
system in question.
- ZMV Rewritten - Movie Support. [Nach, grinvader, ipher]
Added support for subtitles while playing a ZMV. [Nach]
Can now load movies via command line parameter. [Nach]
Added parameter to close ZSNES when movie is closed. [Nach]
Our movie subsystem - ZMV has been completely rewritten from the ground up.
Now features such as rerecording (via states and rewind), appending, mouse
recording, Super Scope recording (buggy), chapters, start types, frame count,
input compression, among other things is now all supported. Note ZSNES can
still load old ZMVs, however it should be noted that ZMVs are somewhat version
reliant and may desync on a version it was not recorded with. Also most of
the new features will not work when using an old ZMV.
- Can now dump ZMVs to AVI and WAV. [Nach, Bisqwit]
For years users have requested being able to convert a ZMV to something
else, it is now possible.
- Added IPS multipatch support. Goes from IPS, IP0, IP1, IP2, ..., IP9. [Nach]
So you can have IPS autopatching apply more than one to a game loaded.
IPS files now loaded from save directory then ROM directory. [Nach]
Making it easier for a user to auto patch.
Fixed silly mistake with size adjustment of IPS patches. [Nach]
So now the very rare broken IPS should work.
- Rewind and ZST code fully merged rewind should now work where save states do
(Fixes rewinding in Super Bomberman games). [grinvader, Nach]
Can now use 100 save states instead of 10. [Deathlike, Nach, Jonas Quinn]
SRAM is now stored in save states and can be optionally loaded from them.
[grinvader,Nach]
Can now select how many rewind states you want. [grinvader, Nach, ipher]
Can now select how much time is in between rewinds. [grinvader, Nach, ipher]
Our state saving subsystem has been completely rewritten (although another
rewrite is planned) to fix many bugs that used to be present. With the ZST
and rewind code merged, it also means no more issues where one works but not
the other. This is also now all done in C making it easier to deal with, as
well as allowing many new features as listed above.
- Parsegen invented (thanks grinvader, gladius). [Nach]
Binary and text config files merged into one and heavily updated.
[Nach, grinvader,Deathlike]
We invented a new programming language (PSR), and a compiler for it (parsegen),
which allows one to keep track of variables in a simple manner for both
developers and end users. Developers can just declare a particular variable
to be tracked and forget about it, letting the system manage everything else,
making it easy to add as many configuration options as one likes. For the
end user, the config file is all in text, making it easy to modify any feature
they like or features for advanced users not changeable from within the GUI.
It also provides a level of future compatibility so users should normally
not have to delete config files between versions. It also allows partial
config files, so users can delete certain settings and have them restored
to their defaults. All this is possible while maintaining a high level of
flexibility.
- Netplay, Modem, IPX code removed. [grinvader, Nach. ipher]
As much as we hated to do this, we had to remove all computer to computer
playing options in order to fix up the other subsystems since the code was
spread throughout ZSNES. We hope to in future versions to reimplement it
and also provide new features.
- Created new macros and greatly eased GUI development and cut down on size of
GUI code. [ipher]
Cleaned up GUI and reorganized it.
[ipher, Nach, grinvader, Deathlike, Jonas Quinn]
Added tab support to the GUI and made good use of it. [grinvader]
Rewrote the load game menu, it can now handle thousands upon thousands of
ROMs at a time. [Nach, grinvader]
Added a custom font system. [ipher, Deathlike]
Nach input boxes (video, path) now have a normal blink rate. [Nach]
Now using our custom GUI should be easier and more straight forward. Almost
everywhere you look you should see a cleaner design and new features, and
less bugs. See below for more specifics.
- New unified ZSNES loader which is also less buggy.
[Nach, grinvader, Deathlike, Jonas Quinn]
Now command line options are handled in a more efficient manner, as well as
making it much easier for us to add more.
- Committed the ZSNES development toolkit. [Nach, grinvader]
Code is now always in executable sections, fixes NX and many other issues. [Nach]
Added utility to auto detect best -march option to compile with, SDL port
uses it automatically. [Nach, grinvader]
For various developers, we now added many utilities to make working on ZSNES
much easier. Some of these utilities should be built into the assembler but
aren't. These new utilities have also allowed us to easily track down several
critical bugs and fix them effortlessly. We also have a utility now to aid
the person compiling to get the best optimization out of their build perhaps
now allowing them to use HQ4x or other filters that weren't possible before.
- Updated build setups. [grinvader, Nach]
Added file dependency utility. [Nach]
All the build setups have been updated to make it easier and more flexible
for one to compile ZSNES and encounter less bugs along the way. File
dependencies can now also be calculated automatically (most notably for SDL),
so one updating ZSNES doesn't run into weird issues with only half of a fix
being compiled.
- Ported much assembly to C.
[grinvader, Deathlike, Nach, Jonas Quinn, theoddone33, pagefault, byuu]
Removed dead code. [grinvader, Nach, pagefault, Jonas Quinn, Deathlike]
Lastly on our big rewrite, a lot of old junk went, and many complex are
annoying features are now in C meaning if you know C, now is a good time to
start helping out ZSNES development.
