Tronica Spider has now been preserved in MAME smile

The game is using the same MCU/ROM as Tronica Space Mission and even the PCB is the same.

There are (at least) two revisions of the game with different inlays. The first revision has a single inlay and the second one has two inlays and some more details.

This is a screenshot of the game:
