Atari 800 core broken in 64 bit 1.7.8

I have tested both the 32 and 64 bit app files directly from Retroarch, installed and attempted to run Atari 5200 games. I was able to initially run one rom, but after that none of roms would work. Retroarch would crash and exit. I went back and installed version1.7.7 and it worked with some sound issues. I had thought the Shield TV update to Android Pie might be the issues, but that is not the case.

Has anybody else had this issue?

Thank you for your time.

I have a similar issue on a Shield TV but with the Beetle Saturn core… Unfortunately it is related to the 32bit & 64bit merge for me . When I use 1.7.8 32bit from website the core loads the roms just fine, but if I use the google play 1.7.8 (64bit) it crashes when attempting to load content…

Will have to wait until they iron out some of these bugs from the merge.
