After a few days of work and much help from BadBoy, I've found out the way to patch the LFDS for always "Gameplay in process". This is my first reserve engineering product, and the experience is great! If there is anything wrong, please tell me so that I can have a chance to improve.

RH7.3
========================
offset xxxxx | org | new
offset 23A38 | B8 | 90
offset 23A39 | 87 | B8
offset 23A3A | F8 | 01
offset 23A3B | 01 | 00
offset 3FECA | 00 | 01
========================

Special thanks to:
StealthEye for the initial idea on patching the cGameDataCnc::Is_Gameplay_Permitted(void)
v00d00 for the wFDS version patch
BadBoy for finding out sub_472C40 = cGameData::Export_Tier_1_Data(cPacket &) and explain the tricks in the wFDS version patch

P.S. I'll find out the offsets in the RH8 version of LFDS soon Wink


Thanks blazer for the xwisp! My dream comes true!
<Ghostshaw> duh
<Ghostshaw> its awesome

well done mate !

When people ask me "Plz" just because it's shorter than "Please" I feel perfectly justified to answer "No" because it's shorter then "Yes"

Programming is like sex: one mistake and you have to support it for the rest of your life

Want the best answers? Ask the best questions!

"So long, and thanks for all the fish."

besides, I think I've found the bytes for RH8, it is quite tricky because it works in another way that is difference from the RH7.3 version and the wFDS

offset xxxxx | org | new
offset 2BBAA | B8 | 90
offset 2BBAB | 87 | 90
offset 2BBAC | F8 | 90
offset 2BBAD | 01 | 90
offset 2BBAE | 01 | 6A
offset 2BBAF | 01 | 01
offset 3DF12 | 00 | 01

I don't have a box to run the RH8 version, anyone can help me to test it? Tell Me

I run the RH8 version. Are you manually patching or are you using a tool or script?

I patched it with a hex editor and upload it to the server for testing.
After the patch works, I deleted the "excess" patched binary and patch the unpatched version with a patcher program, which is modified from the patcher.c from the scripts.dll/scripts.so package.

I'll test your patcher.c on my RH8 binary...then you can release it! Smile

I link the compiled version with Source Readme.txt so that everyone can use it.

UESir28:
that's C but not C++ Wink
btw, did you test the rh8 version for me? it's syntax should be correct, but I don't know if it work or not.

Yes, I forgot to post the command for compile and run it:
gcc -o gameplay_in_process_patcher <name of the C file>
chmod a+x gameplay_in_process_patcher
./gameplay_in_process_patcher <name of LFDS binary>
