As far as I know, no one has made any etm trainers for Halo, why don't you try and do that? The ips file you have works similar to a ppf, you apply it to the default.xbe using ipswin. Goto the tools pager here, then trainers (
http://www.xbox-scen...p?page=trainers) and it's the first one on the list. Once you apply the ips, it will change the size of your default.xbe file to be quite a good bit larger, this is why ppf cannot be used because with ppf, input and output must be the same size. Just apply and reupload to xbox. While in Halo, press in both thumbsticks together to bring up hack list. Downside is it flickers horribly making it hard to read and is sometimes hard to exit the list. Upside is you can toggle the trainer options on and off during gameplay.
