'''Performance bottleneck order:''' | |||
<pre> | |||
VU1 ==> EE ==> GS | |||
As can be seen, the biggest bottleneck for the ps4 is the emulated VU1. | |||
Therefore its Speedhacks will be the most effective for performance. | |||
</pre> | |||
====Debugging through PS4CHEATER==== | |||
<pre> | |||
The program PS4CHEATER can be used to debug PS2 register by adding these addresses into it: | |||
1000000368 (Jakv2 uses this offset) | |||
1000000360 (Emus with older revision use this one) | |||
And change the type into > View as Hex. | |||
Make sure live cheats is on. | |||
One of them will contain the Currently executing offset in the ee's memory. | |||
