to supergogeta:ok, now we start to analize your problem.
6.99kbsyes, this is the correct one of gp4tweak.bin file size. the actual size in bytes is should be 7164 bytes.
16-06-03 15:23 [ ] helmet code patching has been applied successfully. [armhelm]patching for helmet position is fine. it should be ok for helmet coords data to changed.
16-06-03 15:23 [ ] steerwheel code patching has been applied successfully. [armhelm]patching for steerwheel position is fine. it should be ok for steerwheel coords data to changed.
16-06-03 15:23 [ ] arms code patching has been applied successfully. [armhelm]patching for arms position is fine. it should be ok for arms coords data to changed.
now i wonder if you can't change coord values for arms and steerwheel. as far as i saw in the supplied information above, everything is fine.
but try this whenever arms and steerwheel coords worked or not. run gp4tweaker again and change x-axis for both arms and steerwheel for driver #1 (m. schumacher) into 2.0000. then press 'apply' button and run your gp4 game. watch for arms and steerwheel for schummy. have a try!
ps;
don't forget to press 'apply' button before you quit gp4tweaker.
