Hi,

Sentaro21 just updated the parameter for F5 mode into last revision of PTune3 (v0.25). PLL mutiplier has been changed from x26 to x25.

only few changes are needed in gint to reflect that change :

all are located in file src/cpg/overclock.c:

the following definition is to be added:

#define SH4_PLL_25X 0b011000

right after line 32 defining the SH4_PLL_x26 modifier

and then line 425 (considering new line number) should be changed for the following one:

.FRQCR = (SH4_PLL_25x<<24)+(SH4_DIV_2<<20)+(SH4_DIV_4<<12)+(SH4_DIV_4<<8)+SH4_DIV_8,

and we are good to go...
