The best solution (in my opinion) is to NOP(HEX-code: 909090909090) out the jne at address 40B744 (HEX-offset: AB44h). When we changed this, the next start we recognize, that M.G.95 accepts every serial#, but it doesn't stay registered, when we restart it. A register dialog pops up, where we should enter our serial#. To make this vanish, we change the jump at adress 405C47 (HEX-offset: 5047h) from je to jne (HEX-code: 0F85434010000; can anybody tell me the hex-code to make this jump an unconditioned jmp?). 2. As mentioned above there are two patches to be made. 3. There could be a check if we have changed the MEMO95.EXE file. Another problem might be that the program checks the serial# every minute or something like this and kicks us out if we only have patched the two offsets I metioned above (Never seen such a program, yet). 4. Actually I encountered no problems when patching the code, but there's one strange thing I saw in W32Dasm. There is a hardcoded string saying 'The program has been modified!'. Normally this is the error message when a CRC-check has discovered that the file has been modified. This check doesn't work in M.G.95 or the string is only a fake. Now I quit to play my 'registered' version of M.G.95 for a while. ;-) Bye. LaZaRuS LaZaRuS
