I have also created a trainer that does all the above stuff mentioned for you automatically. All you need to do is:
home.exetel.com.au/dyjakon/nfsmw_ws.exe
1 - run the game (NFS-MW)
2 - enter the game playing state, eg. resume your carrer,
3 - alt+tab back to the desktop
4 - run the trainer, press the patch button
5 - alt+tab back to the game and enjoy.
However still a lot of testing needs to be done, so if the trainer doesnt work for you, use the manual method.
Also use this at your own risk... yada yada ... bla bla ....
save any documents u have open before u try this app since it access the ram and may crash ur pc.
Enjoy peeps, enjoy :D
P.S. I noticed that sometimes the addressing of these values change when you launch NFS and restart ur PC. So im not exactly sure how to make this trainer work every single time.
Does this work with 1680x1050?
There are many trainer kits out there, TCK, TMK, MTK, etc. - I'm sure a trainer can be made.
