Retroarch on Vita. intellivision archives and scanning not working?

Running Retroarch 1.77 on a vita.

NES, SNES, Genesis, 2600 games work great!

They are zipped. If I run the archive, it loads to black screen. If I “open archive” then run the bin, it crashes. These games work fine on my desktop.

Scanning the intellivision folder freezes at about 140 roms. There are only 240 files in the folder.

Anyone else have this problem?

Also, Sega CD CUEs seem to crash retroarch. (I haven’t checked if the referenced bins are spelled correct, but same games work on my desktop) …

Thanks!
