ST7735R LCD shield w/ SDcage - not working on Mega 2560?

tack:
SPI isn't on 11,12,13 on Mega2560

They are just normal pins, that's why there is no difference in speed.

The SPI on Mega2560 is on 50,51,52 and the ICSP header. 53 is hardware SS.

Sorry, but didnt you thought that there IS a difference in speed?

And I am using these pins on Mega with sample code and it "works" , but there is described slowness in speed of redrawing... Might these be solved with soldering a wires and reconnect it on above pins you spoke about?
