Summary MESS-specific 06049: ibmpcjr [kingqst, mouser, pitfall2, scubavnt] : some softlist games are broken
Description Some of the games in the ibmpcjr softlist seem to crash instantly or cause major graphical glitches. All of these bugs listed below did not happen when I tested MAME 0.144 in PCjr emulation.

Maze is invisible

Kings Quest-
Instant crash with pink stripes

Pitfall II-
Crash with pink stripes. A string "C123456789" appears and moves around randomly but that's it.

Pink stripes. Graphics majorly freak out along with collision if you start the game

Steps To Reproduce
Additional Information Regression; Tafoid has already spotted a possible point, between 0.148u1 and 0.149.
Regression Version 0.149
Affected Sets / Systems ibmpcjr [kingqst, mouser, pitfall2, scubavnt]
