HalfNES Version Notes:
Fixes a couple of very noticeable bugs - reset command works and Gradius works right again.
-The Reset command didn´t do anything, now it does.
-Gradius and Devil World work properly again and Back to the Future works better
(I used && when what I meant was ||).
-I now realize that file loading doesn´t work very well on a Mac
(and the file dialog is terrible too!), so I´ll work on that.
A new release of HalfNES for a new year. Fixes too many graphics and sound bugs to list here and adds second controller support. See the readme for details.
Wow, it´s been a while.
Added Player 2 controller support, can remap the buttons in the settings.txt file.
Improved rendering: Gauntlet runs full speed on my computer when it didn´t before,
the status bars of Zelda II and Ninja Gaiden now look right,
in general performance is about 20 percent better because the drawing code is more efficient.
Back to the Future works but has random unexplained glitches.
Made a few additional tweaks to the MMC3 code, now Might and Magic works but SMB3 is unchanged.
Also eliminated a potential crash after attempting to load a game with an unsupported mapper.
Changes to the audio code: Excitebike and a lot of other early games that
used the sweep feature on the square wave channels should be correct now,
Super Mario Brothers finally sounds right.
Also, this works. http://kkfos.aspekt.fi/2010/11/14/4-bit-pcm-on-nes-using-the-pulse-channel/
