You are given 4 options for what to do when this happens, all of which are pretty self explanatory. UPS checks if ROMs are valid in order to protect you from potentially damaging your ROM. An invalid file is a ROM that has been hacked previously, essentially it is not in the original form it was when you downloaded it. Notice the options under “If original file is invalid.” Right now you must be wondering what an invalid file is.

Now when you open the program you will arrive at your main menu.Īs you can see there are three options, applying a patch, creating a patch, and getting patch data. For this demonstration I will be using NUPS, created by my good friend Nintenlord because it is the best UPS Patcher out there. So now unto the actual tutorial for using the UPS patchers. The basic rundown is that UPS is more efficient and can patch files over 16MB which IPS cannot do. Now, that’s a lot of words that you might not understand. command line functionality to patch files and create patches directly instead of using the UI.Windows / Linux GUI patchers, core library written in ISO C++9x.Very important for others implementing this algorithm. Odds of a false positive are 1:4 billion with CRC32, and CRC32 is 100x easier to implement than eg MD5SUM, etc. We use CRC32 as this is designed to test integrity, not to prevent malicious checksum conflicts. CRC32 checksums on the original, modified and patch files guarantees patches will not apply to the incorrect games.The same patch can both patch and unpatch a game. simple file format, easy for anyone to implement.UPS format also has several other advantages over IPS format such as: UPS patches allow you to expand the ROM without having to do use the dual patches method like StealthPatch, making it more efficient and easier to understand. Most contemporary GBAFE hacks use this patch format. UPS FormatĪs mentioned before UPS is a better format for patching files. UPS is a better form of patching and this tutorial fully endorses using the UPS format over IPS format.

Now before we begin I would like to inform you that there are two types of patch files dominantly used in GBA hacking.
