Serious Sam 1 and 2 HD Trainers?

Would it be possible for anyone to make new trainers for the steam versions of the games? None of the old trainers work anymore and have not been updated in years. Also a way so the trainer does not disable achievements would be fantastic

Possible cheats for both games
Max and unlimited ammo
No reload
Max and unlimited health
Give all weapons
God mode
Massive jumps/gravity mods
