Game lib

MarioRossi93i · January 16

i have a problem (ok more than one ). i can t find game lib in /data/game/lib nor in process/range list when i run gg, but it is present in apk. so i can t use chainer anymore because cd and cb are empty. any suggestion?

sorry for my bad english

MarioRossi93i · January 20

thanks @nok1a i ll try it with chainer asap. meanwhile i did some test manually and i manage to get it works.

when libRealRacing.so is not present in /data/app/etc... i get this using gg.getRangesList("com.ea.games.r3_row*base.apk*bss"):

Script terminato:
Start: 0x7CF1C07000

	},
	[3] = { -- table(6181b0d)

		['internalName'] = '/data/app/com.ea.games.r3_row-64kIDFJ_5MVEqukwLYrwhQ==/base.apk:bss',
		['name'] = '[anon:.bss]',
		['start'] = 536842260480,

		['name'] = '[anon:.bss]',
		['start'] = 536852029440,
		['state'] = 'O',
		['type'] = 'rw-p',
	},
}

the first one starting at 0x7CF1C07000 is the working one.

Now i have a new question:

all ranges have same state,type,name. how to get the correct one writing a script? by checking size?

furthermore, if the game library is present, the getRangesList function only returns the last 3 ranges you see. Any ideas for managing everything via script?
many thanks in advance

To be honest i don't think it can work using size calculation. You will get all the BSS parts. But the size could differ. Did some tests:

32 bit

64 bit

And then you have your size which is 32000

MarioRossi93i · January 20

I imagined the size might change. the only idea I have left is to try to load a known value for each range and see if it is found, otherwise move on to searching for the values. I'm a little worried about the time this check will take...

nok1a · January 20

Personally with my current knowledge on the topic i just think that finding some unique values in the executable is enough.

Search unique value. Then call gg.getRangesList(). All ranges will be displayed with there start and end address. In my case i know that the UTF8 string "libRealRacing3.so" resides in the Xa region of the executable. So i just search it and then get the first address of that char. So i know that's the right executable. But since lack of infomration on what your script does i adjusted my function getLib() for it to work with getRanges() by calling gg.getRangeList() to obtain the start address of the executable in which the string i just searched is located. Since the getRanges() function expects a table from gg.getRangeList(). Then knowing that the executable is divided in to 4 segments

but the chainer only will take the first segment that includes the "w" permission i just increment the table i took from gg.getRangeList() by 3 since the third segment is the one the chainer use since it has the "w" permission.

I test on 2 emulators that are 32 bit and on the 64 bit as well. Both worked. And as you can see in the post of

Game lib (#c64p69nw)

It worked for Count_Nosferatu after executing the script as expected.

Doesn't really work. It is not clear which of base apk to count from.

gg.setRanges(gg.REGION_CODE_APP)
t = gg.getRangesList('^/data/*com.ea.games.r3_row*base.apk*$')

for i = 1, #t do

That's not my script. You changed the search string and added your own string in it. It's also not how you implement it in the chainer and removed the function to i guess?

Also i did not read the full chainer script which was very big mistake of me, so i did not knew you needed to load results in order for it to work. I do now. So will implement the function in the chainer script.

That's odd if it worked for you before, do you get any results if you manually search libRealRacing3.so in UTF8 in region code app ?

MarioRossi93i · January 21

@nok1a thanks for your help, I solved the problem, the chainer is working now. now I just have to do some tests to select the right range in the scripts. unfortunately searching for a string takes too long, so I will directly use a getValues() to test for a known value.
I'd say the problem is solved, thanks everyone!

chainer.rrnolib.lua

MarioRossi93i · January 22

my problem was the chainer, and now it is working.

check all ranges for a known value and select the one (and only) that works. pm me if you need help.

by the way, to also select the bss add an * and a $ (optional) after base.apk*$

Count_Nosferatu · January 22

I think that the problem has not yet been solved.
It is not clear which range should be used.
The script finds many ranges with ['type'] = 'rw-p'

t = gg.getRangesList('com.ea.games.r3_row*base.apk')
for i = 1, #t do
	if t[i]['type'] == 'rw-p' then
		print(t[i])
	end
end
