Summary	01964: gtg2j: Access Violation
Description	The game crashes pretty early at src/emu/video.c:222. It appears the "device" parameter is invalid.

No.03947 Tafoid Administrator Mar 11, 2009, 19:43	I can't get a duplication on gtg or gtgt. In any case, those sets are not the same as gtg2 and clones. (which also work fine for me in 0.130)
