BlueMSX won't load games on NESC/ra1.7.7

I have recently updated my NESC(not SUPER, just 8-BIT) to run Retroarch 1.7.7. Tried using BlueMSX to run ColecoVision games. And when I try to load the core for BlueMSX and later load the games from that core, it kicks me back to the main menu.

Furthernote, I know I can change the hardware type in Options via Quick Menu. But that is unless I select a different core then back to BlueMSX just to get into the Options and change it from MSX1/MSX2 to Colecovision.

Anyone know how to get it running?
