There is actually a way to
skip a mission. Try out
TimeVault. All you have to do is to renamed the
timevault_main.scm to
main.scm and replace your original file in Vice City --> data folder.
WARNING: Please make sure that you've backed up your original main.scm, otherwise you won't be able to pass anymore missions by yourself. All you have to do is to put this new main.scm file instead of the older one, backing up the original one of course, load your save game, start the mission, and you'll be instantly given the mission rewards. After that, save the game, exit, and remove put back your original main.scm, that you were supposed to back up. After that, re-enter the game, and carry on normally with the game.
But, as Andreaz said, if you find this TimeVault method way too difficult, you could simply post in
this topic a Save N' Play request, uploading your file
here, and giving us the save game download link. You save game can be found at
