Stubbs the Zombie in Rebel Without a Pulse is a third-person action video game developed by Wideload Games and published by Aspyr Media, and built with the Halo engine. The game takes place in the fictional city of Punchbowl, Pennsylvania at its opening ceremony in 1959. It just so happens that the city, founded by Andrew Monday, Maggie's son, has been built directly on top of Stubbs' not-so-final resting place.
Stubbs rises from his grave as a zombie and decides to get his revenge by eating the brains of the inhabitants of Punchbowl, quickly creating his own army of the undead, causing increasing amounts of havoc as the zombies clash with the various militant factions of the area. During the chaos, Stubbs kills Otis Monday by blowing up his house after a brief reunion.
Shortly before this, in a spoof of the war film Patton, Stubbs stands in front of an American flag hanging from a barn wall and gives a speech to his zombies. Though the speech consists only of the word "Brains" said in many tones with limited gestures his zombies apparently understand him well enough to let loose a cheer of "BRAINS!" before shuffling away.
I'm trying to run the Steam version at 1920x1200 at 60Hz have edited edited blam.sav within my Profile just as described in the OP, inserting 80 07 B0 04 as the hex values.
However on launching the game my monitor (Dell 2407WFP) displays a 'can't display this resolution' message.
Any suggestions as to what I may be doing wrong would be welcome, or does this hack not work with the Steam version?
