 ## Patch note
+### v1.3.3
+'aspect ratio 10:3 mode' has been changed to 'correct aspect ratio mode' (follow sar value(*0)) \
+Color conversion speed has been improved \
+Simplified Chinese(简体中文) translation has been added (by LITTOMA) \
+Italian(italiano) translation has been added (by dixy52-beep) \
+*0 if video size is 800x240 and no sar value is set, it autmatically apply sar 1:2

 ## Performance
 
-Software decoding
-* 256x144(144p)@30fps(H.264) on OLD 3DS
-* 640x360(360p)@24fps(H.264) on NEW 3DS

-Hardware decoding
-* 854x480(480p)@40~50fps(H.264) on NEW 3DS
+⚠️ Decoding speed depends on encoder option, video type, video scene, etc... \
+⚠️ This table shows average fps, so you may hear stutter audio if you use this framerate. \
+(Lower video resolution or framerate in that case) \
+Software decoding in this table uses only one thread not multi-threaded decoding.
