reply to myself AWEHaWHeUAhwe:

does anyone knows how to use the matrix (xmtrx) registers in sh4??? i want to try the ftrv instruction but i don´t know how to work with it.

there´s a sample code i´ve found (haven´t read it all):

Oh! i´ve noticed that the sh7750 manual posted here hasn´t the dreamcast special asm instructions (like fsrra). Is there a manual with this instructions documented???

Thanks!
