I've noticed the "the 'hr_hires.c #1.-1' bug" myself sometimes when I'm trying to play in full screen in Dosbox and have figured a way around it.
1. Run MSDos Prompt
2. press Alt+Enter (to go to full screen)
3. At the prompt type "exit" to close MSDos window (still in full screen)
4. Now run Dosbox
5. Press Alt+Enter again to go to full screen for Dosbox
6. Type in the mount commands so you can play your game
7. Run game
So far I have had no problems for running Lion and Wolf in full screen modes following this method. *Also* if you wish to go back to desktop (temporarily) pause Lion or Wolf using 'Space Bar' then press Alt+Enter, remember after using this method always pause before you switch to full screen or back to windowed mode.
Hope this helps those who are having the error.. (still no sound with Lion but I'll be fixing that when I buy the game)
