Is this a thing? Because there are some addresses, such as timers, that use 8 bytes. I am currently testing one in a GameCube game in Dolphin, and there is no good way to keep track of it with the current options in Cheat Engine.

Update DB's custom type for an 8-byte size.

I'm not entirely sure how to do this, mainly because some of the coding changes slightly between 2 byte and 4 byte.

Are you sure this is QWord in Big Endian? Maybe it is just DWord in Big Endian.

If I understand those terms correctly, then it is definitely a QWord.

CE custom types can have any size. Unfortunately the result must be in range of 32bit unsigned integer number or 32bit single-precision floating-point.

So there's nothing I can do for this?

It is possible that those timers will have values bigger than FFFFFFFF?
If not, you can use "dword big endian".

I have already confirmed that the timer can go up to FFFFFFFFFFFFFFFF before it resets to 0.

Unfortunately, max value for custom type integer is 0xFFFFFFFF.

We could convert this QWord Big Endian to sp-fp value, like this:
0x0 - 0.0
0xFFFFFFFFFFFFFFFF - 1000.0

So you should be able to do scans. Do you want such Custom Type?

Sure, I can give it a try.

0x0000000000000001 will be 5.421010862E-17
0x0000000000000002 will be 1.084202172E-16
0x8000000000000000 will be 500
0xF000000000000000 will be 937.5
0xFF00000000000000 will be 996.09375
0xFFFFFFFFFFFFFFFF will be 1000.0

Note:
0xFFFFFF0000000000 will be 999.999939
