We've added many new options to our trainer, bringing it to MEGA status. We only updated the 1.5.04 trainer and will also release a mega for 1.5.05 when it's released.
If it were me, I'd include simple dropdownboxes (just like in some old trainers for really old games) to allow you to chose the keys for the cheat options, that way the custom key's tool would not be needed(I personally don't really find it useful, tho some people might) and also you could just set keys for the cheats you need/wana use and ignore the rest. Some trainers are really off the chart complex for guys like me who just use funds/ammo cheats I'm really shocked with the amount of options some trainers have.
The current Mega for 1.5.04 will work for ALL versions properly patched to 1.5.04 (not using the no-cd fix which reverts the russian ver back to 1.5.03).
