Got mine and seems to work fine. I had some of those issues and it not playing talespin or roms I just patched. Though discovered that full rom set I had for some reason everdrive didn't like some of those roms so downloaded from different sites and those worked fine. Oddly for talespin only a hacked rom would work. So anyone having issues again download a different version of the rom you have or from a different source and check date modified to make sure your not downloading the same one. But honestly like the everdrive 64 works fantastic another great flash cart. Btw using pc engine duo.
Btw must sat stone age gamer packed it very well and the slip cover was a great addition.
