RPCS3 and Cheat Engine

If the value you are looking for is higher than 255,you will not find it because rpcs3(or maybe that's how the PS3 work,I don't know)uses big endian
For values that use 1 byte(0-255)you can just use byte
For values that uses 2 bytes(0-65535)you need 2 Byte Big Endian
For values that uses 4 bytes(0-4294967295)you need 4 Byte Big Endian

The latest version(and some older)are using this memory region 300000000-301FFFFFF
You can use that instead of scanning your whole ram "all day"

CE works fine here.

This is correct, however for some games, I had to change the memory region to 300000000-32FFFFFFFF.  I know this because certain values wouldn't show up, and then I tested the default memory region settings and those values showed up under 32XXXX, etc.  Games where values are in the memory region is 32XXX, etc, you can set the scan options for 3200000000-32FFFFFFFF.  That might be one too many 0s or Fs, if one of you tries that and it doesn't work, remove a 0 and F from the end.  

Stuff like stats, item quantities, etc you find one of the values, and search the memory region, and the others are usually right near by.  It's in hex, so keep in mind that in the memory viewer, 9999 will look like 27 0F.  So if the value is 5, and you want to change it to 9999, it will be 00 05 in the memory viewer, and you change the 00 05 to 27 0F.  For those values in hex, you gotta change the 00 to 39 to get 27, and for 0F you put in 15.  Let's say for Tales of Graces F, you find one of the values for the usage on one of your arts.  You know the max  9999, and you got 268 usages on it.  You'll notice by searching the memory region that the usage amounts for your other arts are in the same regional grouping, and you can modify those as well without actually searching for their values individually.  Let's say you got tiers of materials, like gems, etc.  Search for the quantity of one of them, and items of a similar type are often grouped side-by-side in the same memory region.  Rock (S), Rock (M), Rock (L), Rock (XL).  Let's say you got 20 of the S ones, and 5 of the M ones, but don't have L or XL, but S and M are grouped side-by-side in the memory region, with this you can easily determine that the following 00s are the quantity for L and XL rocks, and you can change those values to 01 to put them in your inventory even if you don't have them.
