PS2 Roms CHD ? Anywhere beside Internet Archive?

Do they exist anywhere else beside internet archived ? My Hard drive got damaged and lost my ps2 library , I spent hours organizing and converting them to CHD. I don’t want download iso again and convert them. My internet is capped and trying not to waste bandwidth.

Is my only option waiting for internet archive to come back alive ? Or anybody has a source to get the CHD versions ? I even tried private trackers but they all don’t have chd. Would appreciate some guidance here .
