Run Bwych and select T for Tandy sound and T again for Tandy/PCjr graphics.

The game wasn't patched to run 3 voice sound, but it automatically works on the jr, albeit with an initial hum, which goes away on the character select screen. If you run sound3v before the game, it prevents the hum from ever occurring, not that it's a big deal either way.

Now that you've got the game running, you are in for a treat. This has some of the best music on a PCjr, and the DOS version is the only version of this game to have in-game music, as far as I'm aware.

I tested Bloodwych thoroughly on DOS 5 with jrconfig, and didn't encounter any major glitches. When playing it on DOS 3.3 with pcjrmem, however, it kept crashing, sometimes at the character select screen, and sometimes at the start of the game. I'd recommend the earlier configuration.

Further testing shows it also plays well with DOS 5 and pcjrmem. However, using DOS 3.3 and jrconfig, I had the game crash a little while into playing it, so I fear it doesn't like DOS 3.3 very much.

Now that we're done with that, I need to mention some additional caveats. The controls are a bit wonky. The mouse is laggy, and appears to skip frames, making it an unreliable tool for both moving the character and selecting items from the menu. This gets frustrating fast. What I found works surprisingly well, however, is using the keyboard for movement and attacking/defending, and the mouse for menu selection. That's why I've included the manual in this folder, so you can learn all the necessary keys. 

Unfortunately, for those who don't have a mouse, or prefer a keyboard only, player one needs numpad 5 as the menu select key, and numpad 5 doesn't exist on the jr keyboard. I tried the normal no. 5 key, but the game doesn't accept that. So, unless you're one of the lucky few who has a full-sized keyboard attached to their jr, you will need a mouse to click on the menu items.

I've also had no success running a two-player game. The game just seems to either freeze or crash in two-player mode--not that it would be too much fun having two people crammed on the same small keyboard for any length of time, but it would still have been a nice option.
