I have make a version of the Syobon Action - PSP running fullspeed at:
* cpu frequency: 133 MHz
* ram frequency: 133 MHz
* bus frequency: 66 MHz
for increases your battery's life.

fullspeed for until the castle phase for 133/66, then I compile one version:
* cpu frequency: 222 MHz
* ram frequency: 222 MHz
* bus frequency: 111 MHz
Its still low clock, then increases your battery's life. For who can't get in castle phase, the 133/66 version still a good version. Sometime I will make a hybrid, changing the clock for the each phase. Test this game its a hard task for me (sorry for this).
