I've had a bit of a breakthrough with running some games in JPC-rr. This is not a solution to every game, but it's opened up a few more possibilities. Some games use the DOS4GW extender, which JPC-rr doesn't always seem to agree with. However, there's an extender that actually works: http://dos32a.narechk.net/index_en.html To use this, delete the existing DOS4GW.EXE file, copy over DOS32A.EXE, and rename it DOS4GW.EXE. Then you can import the image with the new extender. (If the game has DOS4GW built into its executable, you can force it to use DOS32A by doing "DOS32A xxxxxxxx.EXE") I've successfully gotten a couple games to work that didn't work before. This will cause some games to boot and then get hung up on loading screens, but it's a good start.

Awesome work! Any idea if this will change the games' behaviors at all?

I haven't tested it enough, and I doubt anything would change, but we'll see what happens. The games I got working at least appear to be running properly.

The different DOS extenders are often interchangeable. It's unlikely that game mechanics logic depends on their differences.

I modified the rules to allow running games with DOS32A.

I don't know what any of this means and I'm not sure how to set it up, but just letting you know I had trouble getting Mice Maze to run in the past because of some error. I wonder if this breakthrough fixed the error...

I took a look at it and it's not DOS4GW related. You'll know if it is because a couple lines about DOS4GW will show up in the command prompt. Mice Maze looks like it has some issues with the FPU and it also uses some invalid instructions, so there's nothing that can be done at this time.

Saw some news about a DOSBox fork today. No idea if it has savestates and/or movies, but it seems to be focused on accuracy.

The main site for this fork says it hopes to be able to emulate Win 3.x and Win 95 as well.

Yes guys, recently I thought about adding rerecording to dosbox, at least to annoy natt into implementing doshawk one way or another already <_<

I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.
