StellaDS v8.1 is released. StellaDS is an Atari 2600 (VCS) console emulator for your DS/DSi. To use this emulator, you must use compatibles rom with a26/bin format. Twilight Menu++ wants to see the file extension be .a26 (you can just rename .bin)

StellaDS Changelog:
Added new Favorites system so you can LIKE/LOVE any game - press SELECT on the Game ROM loading screen.
TIA optimizations for another frame of improved performance.
CPU optimizations for another frame of improved performance.
Thumbulator optimizations for the LDR3 instruction to help some CDFJ games.
Most VBLANK and HBLANK optimizations now removed in favor of improved accuracy (improved performance allows us to ditch most of this).
Refactor memory to buy back almost 250K of DS RAM for future expansion.
