The desired result is the conversion of the. You cannot play the IPS or USV files therefore patching of the file is required. The process of patching means that we change or update the original content of the GBA file so that the content of the IPS or USV files keep the GBA format. In order for this to happen we need a few things. You need them because they are the games you want to play. For Pokemon games, the ROM hacks change the content of the game. Next you need the base ROM or the ROM the hack is based on.

For example, a ROM hack Pokemon Gaia uses FireRed as its base game. the app or program you use to apply an IPS or UPS patch. The gist of this is that we’re patching an actual Pokemon ROM into a ROM hack or whatever the contents of the IPS or UPS file is.įinally, always make sure you have a separate copy of the original Pokemon game ROM because once the patch is ready, all contents of that ROM will be modified and gone forever. There are several reasons and the first one is that the IPS or USV file is unreliable to begin with.

In short, it’s not a good copy or it just wasn’t programmed properly.
