Hey!! I'm having the same problem. I am using XBMC and i have 4200+ .ETM files that read fine, except for the .etm files (of which I have about 15) for GTA: San Andreas. I dont even get the little yellow yield sign in the bottom right of the game when in the programs folder like I do all of my other games.
Is there something that you have to do with the .etm trainer file other than going to (in my case) E:/xbmc/system/trainers and putting the file in there with the rest of the .etm trainer files?

If anyone knows where or what I need to do to get this trainer working please let me know. I love this game and have beat it twice, but now I want to go have some fun without all the putting in codes everytime you get close to dying that i'm doing now.
If someone out there has a trainer for this that they know works, could you point me in the direction of where to get it..........please?

?
Thanks!!!
