Hey RG in this tutorial I will show you how alocate natives function .
Note: this tutorial focused on GTA 5 , however this will work in Any Rage (RockStar Advanced Gaming Engine) Based game.
Let's get to the tutorial
1. Open IDA
2. Open Last GTA V .elf
3. Click Alt+B
4. its the most tricky part ( we need the value of 'lis %r3' ) that = 3C60 , and we need 2 first bytes of any native hash ill take example with GET_PLAYER_PED = 0x6E31E993
5. so in that case it will be 3C606E31 , so we enter that in the string box and check the checkbox "find all occurences" than click ok
6. now it will take some time until you get the result usual there is only one result but if there if few make sure to chose one that much the actual native hash you searching for and than double click it .
it will look something like
seg001:00424100 sub_4240F4 lis r3, 0x6E31 # 0x6E31E993
7.after you duble click it you will see
seg001:00424100 lis r3, 0x6E31 # 0x6E31E993 seg001:00424104 lis r4, ((off_1B9B2D8+0x10000)@h)
Depends on what native you search but you got the idea
8. now you have to click on (off_XXXXXXX) in that case its the (off_1B9B2D8) !
9. and it will bring you here
seg021:01B9B2D8 off_1B9B2D8: .long loc_1525450 # DATA XREF: sub_4240F4+10*o
you have to click the (loc_XXXXXXX) in that case its the (loc_1525450) !
10. and you will see something like that
seg001:01525450 loc_1525450: # DATA XREF: seg021:off_1B9B2D8*o seg001:01525450 mflr r0 seg001:01525454 bl sub_1776544 seg001:01525458 stdu r1, -0x80(r1) seg001:0152545C std r0, 0x90(r1) seg001:01525460 mr r31, r3 seg001:01525464 lwz r3, 8(r31) seg001:01525468 lwz r3, 0(r3) seg001:0152546C extsw r3, r3 seg001:01525470 bl sub_41EEF0 seg001:01525474 lwz r4, 0(r31) seg001:01525478 stw r3, 0(r4) seg001:0152547C addi r1, r1, 0x80 seg001:01525480 b loc_17765A8
and here we go the second (bl sub_XXXXXX) is our native function in this case its (bl sub_41EEF0)
Hope that it helps !
