I know this topic has been raised many times in the past, and I have read up on all the old threads, but I cannot find the answers I am looking for.

I have been going through my collection of Sierra games from the 80s and seeing if I can get them to all work properly in DOSBox. Most are fine, but I am having some issues with Winnie the Pooh in the Hundred Acre Wood, and Ulysses and the Golden Fleece, the latter being a PC booter.

Up front, I should mention I am using the latest SVN builds of vanilla DOSBox.

For Winnie the Pooh, I can get it to run in CGA mode, with either the cyan/magenta or RGB colors. Composite mode also works fine when using F12 and control-alt-F11 to switch modes. My problem is that I cannot get Tandy/PCjr graphics and sound to work. When I use machine=tandy the graphics are displayed in grey and black with thick vertical black lines, and the sound is standard PC speaker. It seems that the game will not recognize the Tandy mode in DOSBox. Changing the machine to PCjr results in the game freezing/crashing on the Sierra logo, which is also discolored and looks corrupted. I thought that perhaps there is a problem with my game files, but I tested them in ScummVM and the 16 colors + Tandy sound works perfectly when I set the emulation type to PC Jr. I am wondering if there is a known issue with this game in current builds of DOSBox or if I am doing something wrong with the settings. Perhaps ScummVM has some built-in hacks that get around certain problems with this game.

With Ulysses and the Golden Fleece, it loads fine, but I cannot figure out how to switch to RGB mode for CGA graphics. Composite works fine with the F12 button, but control-R does nothing. I have seen screenshots showing the PC booter version working with RGB. Does anyone know what settings or commands I need to use?

I have attached screen shots to show what it looks like when I use "machine=tandy" in DOSBox, vs. using the default settings in ScummVM (which appears to be 16 color Tandy/PCjr EGA graphics).

Ulysses and the Golden Fleece functions similar to Adventure in Serenia. You need to press ScrollLock to advance output when 3 or more lines of text are displayed in order to get to the command prompt. At the command prompt you can press F1 to toggle between text/graphic and text-only display, and F2 to toggle between composite-style and RGB-style graphics.

For Winnie the Pooh, it's a bit complicated. There is a separate executable (MAINJR.EXE) for PCjr/Tandy that is not included in some copies that float around on the net. Also, some steps may be needed to get the PCjr/Tandy program to work correcty in DOSBox depending on how it was deprotected.

Thanks for this advice. I figured out that I needed to use the key mapper in DOSBox to bind scroll lock to another key. On Macs the F14 key is meant to be the equivalent of scroll lock, but DOSBox reserves F14 and F15 for decreasing/increasing brightness.
