I'm looking at CE v5.5 pointer scanner and it has two options,
Reverse pointer scan- I understand how that would work.

Old pointer scan- What method does that use?

I'm just about to start my own pointer scanner and was wondering what my best options are.
Atm i'm going with an injected reverse pointer scan.

The old pointerscan works by starting from every static address and then go through every possible path and store the path if it encounters the target address
As you may guess, it's slow

Ah ok thanks for the reply.
I was guessing it was slow before i finished reading your comment.

I'll try the injected reverse method and see how it goes.

Injection probably won't make much difference with the exception of getting more results (the injected dll also allocates memory)
CE's pointerscan first reads ALL the memory of the target process looking for pointers(the initial progressbar), and when done starts looking up the links. (You can even close the target after the initial scan is done) So from that point on it's equal to an injected pointerscan

I'm not gonna be injecting anything to scan, the memory scanner is injected already. Thats why i called it injected reverse scan.

I'v already taken care to avoid reading the scanners own memory.
I bypass it when reading the memory regions and i dont scan anything allocated from the scanner itself. I get the same scan results CE gets.
Took me awhile to tweak it just right but i managed to get it working just right and keep the scan speeds.

I'm keeping the layout as close to CE as i can so it's easier to use.
