tl;dr Downloading Retroarch 1.9.1 instead of the latest version may help for some users getting the 'coreInfoTable' error.

The installation instructions were pretty easy to follow, and I didn't have any problems setting up everything to get the addon working. Despite this, however, spawning in the entity gave me a LUA error similar to this:


As it turns out, downloading an older version of Retroarch seemed to fix this issue, and now the addon works perfectly. I got version 1.9.1 instead of the latest version. The older versions of Retroarch can be found under "Other downloads" under the stable builds.

I thought I would post this in case this helps for those getting this error.
