Why using exe compressors?

[TippeX]

and really, you don't need to unpack a trainer, just breakpoint on writeprocessmemory / readprocessmemory in most cases gives you what you need, unless the trainer injects a dll, in which case usually virtualprotect gets you to the area (cos it has to change it to writable)... so all a packer gains in essence (at least to me) is a size change and very little else
