NINTV-DS

What's New:

- .int files are now auto-detected as either .bin(+cfg) or .rom files. This allows you to rename .rom files or .bin files to .int and let Twilight Menu++ auto-launch Nintellivision.
- Slight improvement to the Intellivoice driver to give a minor boost in performance (mostly for DS-Lite/Phat).
- Added new keyclick enable option in Configuration (page 2) that produces the typical Intellivision keyclick when you press the 12-button keypad (on the DS lower screen).
- Added a new level of sound quality 'Ultimate'. The default for the DSi and above is still 'High' as 'Ultimate' consumes significant CPU time but you can enable it on a per-game basis for some of the more simple games (e.g. Astrosmash, Beauty and the Beast, AD&D Tarmin, etc)
- DS-Lite now enables Intellivoice on World Series Major League Baseball - sound quality is a bit rough on the older handheld but very playalbe.
- Fixed save/restore state including when backtab latched is TRUE (Stampede, Masters of the Universe)
- Fix for intellivoice games so there are no more glitches on the updated version of Same Game and Robots.
- Fix for ecs games so they don't inadvertantly write over the last graphics card in memory (causing minor graphics corruption on some games)
- Correction of one intellivoice coefficient value (thanks to documentation in JZINTV) so voice games sound their best.
- Other minor tweaks and cleanup as time permitted.
