In the Articles section you can find general information on
Memory Search and
RAM Search.
To find particular addresses, define your search criteria on the lower half of the Ram Search window, then press Search. This will filter out all addresses not matching your criteria, then repeat the process until you find the one you want. This may require a few assumptions, which if incorrect will not yield the result you want, so it may require multiple tries. If you don't quite understand, then start with super easy values to find. EG the lives value, since you have access to this value in games at all time anyway, it's not like it's hidden data you need to extract, but it's a good start. IE
-Start game, try "Equal to", "Specific Value", "3". Search. Obviously plenty of address will have this number, so need to filter it down even more. Do a bunch of random stuff in the game (without dieing), then press Search again to use the same criteria.
-This time die, and now change the criteria to say "Equal to", "Specific Value", "2". Obviously the lives value has changed, where as not every one of the current results will have, and so it filters out the incorrect values. That is of course, assuming lives value gets stored like that; but without being an expert in cryptography, I'm pretty sure that's how it's done.
-Also trying "Equal to", "Number of Changes", "1" would be stronger criteria, and would filter out more results. By coincidence they'll be other results, eg
0006BA4E|
3, 5, 7, 2, 6, 6,
2, 16, 80
0008AEE4|
3, 3, 3, 3, 2, 2,
2, 2, 2
Pressing 'search' on bolded frames would clearly yield both as valid results, yet we can obviously conclude the above sequence does not keep track of lives. Searching for values which have only changed once would filter out the top one, but still give the bottom one.
-If you still haven't found it, then repeat the process. Die again, search for Equal to 1, plus Equal to Number of Changes 2. By which time you should find it, you can then click WATCH to save this value to your Watch list, to keep track of later.
That was super easy, since we knew what we were looking for. For XYZ coords, things are more difficult, because you don't know "Ah, clearly I'm at x=59041 right now, so I know what to search for", which means your search criteria needs to be more vague. IE you can search for "equal to previous value" when stationary, or "greater than previous value" when moving, maybe clicking specific addresses and 'eliminate' if you can see already that they're not the address you want. However, be warned of the aforementioned assumptions. For example it's common to have the Y Axis on 2D games pointing downwards. So if you jumped, and search for 'greater than previous value', clearly you would not find the value you want.
