i can create a loader but whenever i change some bytes directly in the code all characters are change to hieroglyphs
how can i make an inline patch? can't finde any packers

c2a7_15.11.2007_CRACKLAB.rU.tgz

dumdidum ?????:
can't finde any packers

What you Mean?

1( you cant do inline because not packer present? - pack exe to upx and doo work!!
2( ha ha where is no packer on to exe file! (ms visual c 7.1)

Sorry, possible "inline patch" is the wrong description. I would like the make some changes with an hexeditor, at moment this results in an running programm, but all symbols are changed, so you can't use it. if i apply the patch after it is loaded into the memory (with an loader) everything works fine. I would like to know what kind of protection this is (perhaps some kind of crc-check) and how to bypass this.
Hope somebody could help me

no one here who can explain me that??

(hi i'm new here !!)
hi dumdidum,
can't you do a self patch ?
In an instruction that is not interesting, you do a jmp to "your patchig instructions" (pub them probably at the end of the binary), then you re-jump to the instruction+1 of your bin:
here is a scheme:
inst1
inst2
JMP 1234
inst3
...
...
...
...
NOP
NOP
NOP
Patching inst (example:mov word ptr [adress],9090)
JMP @offset of inst3
NOP
NOP

EOF

Hope this will help you.
désolé si je n'ai pas tres bien compris ta question

The JMP 1234 is a jump to the offset of the first instruction of your patching inst.
So 1234 is the offset of: Patching inst (example:mov word ptr [adress],9090)
