now i'm a bit confused.
my previous 4GB has about 11K latency, as expected, it did have some problem with golden sun, it did boot with bypass AP but osmetimes dim dragon kick in.
now using 1GB lexar i found lying around on my backup cart, it has around 7K latency. now it boot everygame without any problem, golden sun, sonic color, 999, dan not a problem with soft reset.
but the thing is, i totally disabled bypass AP on system setting and individual rom setting.
not that i complain or anything, just a bit confused since everyone said golden sun need to use bypass AP.
