NINTV-DS v4.7 is released. NINTV-DS is an Intellivision console emulator running on the DS/DSi. The Intellivision is a home video game console released by Mattel Electronics in 1979.

NINTV-DS Features:
All known games run at full speed on a DSi or above.
Many games run very close to full speed on the older DS-LITE and DS-PHAT hardware but you can play with config settings to get the most out of these games.
Custom Overlay Support. See the 'extras' folder for details.
Manual/Instruction Support. See the 'extras' folder for an example.
Save Sate support (3 save slots per game).
High Scores for up to 10 scores pre game with various sorting options.
Cheat / Hack support using NINTV-DS.cht (see 'extras' folder and place in /data directory)
Tons of button / controller mapping options. Dual-Controller support (run and shoot at the same time).
JLP support for accelerated functions, extra RAM and flash memory. When loading a game, use the X button to load and force JLP support ON if not auto-detected.
ECS support for ECS games including sound-enchanced games like Space Patrol (use ECS mini-Keyboard Overlay)

NINTV-DS v4.7 changelog:
Major refactor of the audio processor for a big speedup in rendering especially with more than one audio processor (i.e. ECS or Intellivoice)
Switched from individual pixel output to 16-bit (two pixel) output when dealing with scrolling games (big speedup for games like Tron Solar Sailor, Space Spartans, Sorrow, TNT Cowboy, etc).
The DSi now defaults to NO frameskip on any game and the 'High' (best) sound quality.
Aggressive frameskip no longer an option - it's not needed for any game even on the older DS hardware.
The DS-Lite/Phat gets a 15% improvement in sound quality and many of the classic games now run without frameskip.
Fix for B-17 Bomber so it doesn't flash the screen when in Pilot/Gun view.
With the many updates, the config format changed and will be wiped back to defaults - sorry!
