5 years ago what exact version of garbro are you using? if archives can be opened, but images not displayed most likely you got garbro installed incorrectly. try to re-install it from release with executable setup.
as for other dies irae releases, it has so many of them that it's almost impossible to track them all. if you're eager to get 4:3 CGs i suggest you rip them from some earlier release, most of them are supported.

I downloaded the latest version of GARbro and tried to extract images from 相州戦神館學園 八命陣 released in Dies irae & WORLD BOX: Masada Premium but I got an invalid file format error and got .svg files instead. I'm not sure if the encryption format in this release is different than the original release.
Also, light released a patch in September for the Dies irae Kickstarter with the 4:3 resolution CGs for Amantes amentes. I tried to extract files from it, but got an error message: data5.dat could not be opened as resource archive.
