I just released the 0.7.0 version of UGGM. It aims to be an open source replacement of GDEMU_SD from MadSheep. It works kinda differently though. You give it one or several source folders where your games are and it will scan the sub folders and archives to see the games you have. It will then display which one are on your SD. You can copy your games on the SD and it has also the option to shrink the games (it uses GDITools internally).
For now it supports only GDI and CDI. I still consider it a pre-release because I haven't add a lot of feedback, so there may be bugs, but it works well in my case and I use it frequently.
It only support Windows for now, but I want to make it cross-platform (Windows, Mac and Linux) in a future release.
You can download the last version at: https://github.com/Louhike/Ugly-GDEmu-G ... r/releases
Any feedback is appreciated, and I'll be glad to help if you want to participate in the project in any way!
