I’m pretty new to rom hacking but have had a good time applying various patches to various roms in order to give new life to the games that I grew up with (count the renewed interest to the Classic consoles trend). The ips format got me pretty far but then I encountered bps, then ups. I needed a new program for each one, ugh. Not anymore! This single program supports applying all the popular formats and creates patches as well. It can add or remove headers for those pesky snes patches. It has a modern interface. It’s also written in Javascript so it can run in the browser and is open source. The latest is always available on github. Get it!
