a5200ds v3.9 is released. a5200DS is an Atari 5200 emulator running on the Nintendo DS and DSi written by Alekmaul. a5200DS is based on the source code of Atari800. To use this emulator, you must use compatibles rom with a52/bin format. You also need the 5200.bin rom bios to use it.

a5200ds changelog:
60Hz True-Sync. The emulation is now synchronized with the LCD display to avoid tearing (mostly improves scrolling games like River Raid or Vanguard).
New Favorites added... in the menu where you select what game you want to play, press SELECT to toggle between like (yellow heart) and love (red heart). These persist so you can always come back in and see your favorite games.
Improved fameskip handling that always handles player-missile graphics/collisions. This allows the older DS-Lite (and when running from an R4 card or similar) to run most games at full speed without sacrificing core emulation accuracy (no more glitches where shots miss enemies). The DSi and above running something like TWL++ never needs frameskip.
More games run more correctly - fixed games like Star Raiders so the keypad is less glitchy, improved default controller settings for some games, etc.
Numerous tweaks, optimizations and a few specialized hacks that now allow heavy-hitting games to play at or near full speed on the older hand held units.
