This version a800-100b - 1.5.0-4317 - reyalp -test -1 -full , working properly in the Canon A800 .
To gently press the button < PLAY > is entered correctly the < alt > mode.
If you press and hold the < PLAY > button you will enter playback / display mode without problems .
Pressing the button < PLAY > mode is entered < alt > or Canon menu smoothly as desired .
Thanks for the work .
