Patch Checker is a simple tool it needs no explanation... but I shall give you one reguardless.

Patch Checker compares two Patch files and tells you how compatible they are. This is useful if you want to patch 2 patches into one hack, for example a graphics patch over a complete hack.

How To Use:

Load 2 patch files in the desired order that you wish to patch them. Click "Check". 

A percentage will be displayed at the bottom. This percentage is how much of the first patch remains after patching the second one. if there are 1,000 records in your first patch and you have 99% compatibility, you would have about 10 glitches, if you have 200,000 with the same 99% compatibility, you would have about 2,000 glitches.

If you are a skilled hacker and wish to see the glitches or what may be overwritten, clik the "Report" button. It will generate a .txt file that displays all the offsets and hex values that are overwritten and the ones doing the overwriting.

You can manually retype them or edit the glitch areas all you want.

Patch Checker currently only supports .IPS patch files.

ToDo List:
add more patch formats.
