After many unsuccesful attempts to get GB1 running both stable and with voices on XP, I know have it running on DOSemu/Linux with voices and half-way stable. Some crashes seem to stem from the x86 IRET-“bug”, but I also get errors internal to the game:
>We’re sorry, you have encounted an internal game error.
>Please restart your game and restore a saved game.
>If you have continuing problems, please report the following
>information to Sierra Customer Service:
>Error Number: 135
Unfortunately the game’s source code wasn’t included on the CD-ROM, so for me this error message isn’t of great use. But perhaps someone here had the same problem, and has found a solution?
