Final Fantasy 6.7

Your IPS is about the size of a ROM, which means your base ROM has a header / hack as none or that your base ROM has no header / hack has one which result in your patch containing the whole ROM data because of the extra bytes of the header. Make sure both your base ROM and hack either have a header or none. I would suggest removing the header from your two ROM with SNEStuff (one ROM won't have one but you have to rule it out) then remaking the patch. This way the patch will be a lot more smaller and won't contain all the game data (which is close to posting a ROM anyway).
