It looks like the kernel might've been built without dynamic cpu scaling. In this specific case, CPU functionality. You can't create the directory because the directories and files in /sys/devices are tied to hardware functionality. The power.sh script in performance.opk is trying to modify scaling_governor and scaling_setspeed that are supposed to be located in /sys/devices/system/cpu0/cpufreq, but, as you can probably guess, the entire cpufreq directory is missing. My guess is that the performance.opk application is taking advantage of things enabled on the GCW0 that isn't enabled on the RG-350. On my unit the game ran perfectly, I'm using the official firmware 1.5 dated 27 Oct. Download all the different builds of the 2 emulators and run the game to see which one gives the best performance.Īlso, note that firmware 1.7 may have problem with some of the games as someone posted a youtube video showing framedrops while running FBA SFII. Likewise for GBA emulation of which there are 2, gpsp and regba. Your best bet is to try out all the various versions of pcsx4all (there are at least 6 builds that I know of) to see which of them gives the best performance. I did notice that different versions of pcsx4all (done by different developers?) had different performance as I tried another version of pcsx4all and it runs the same game at 40+ fps with stuttering sound.
On my unit, Golden Sun seems to run at full framerate and Tekken 3 hovers around 50+ to 60 fps. In addition to the hardware, the other biggest impact on game performance has to be the emulator software. Under Application, you can set the RG350 to power saving, performance mode etc so make sure you choose the appropriate one first. The SD card used should have minimal impact on the game performance.
