(This video is not the latest progress, not yet uploaded)
Here is a sprite and color hack of Double Dragon for the 7800. It's not a major overhaul... no miracles were worked. I was looking at the sprites of the game and realized they actually look really good and are more faithful to the arcade than most of the 8-bit home console counterparts. The thing that always bothered me was the transparency. I know there's only so much that can be done with 3 colors and to do this game justice, we really need at least 4 color sprites, but here's an alternate interpretation. Originally, I used the original sprites and started by filling in the gaps while also adding a bit of shading here and there with various tweaks. Doing this meant having a blonde Billy was no longer viable, so his hair is now dark red-brown. However, as of late Aug, 2016, I've redrawn the player sprites from scratch, trying to match the arcade proportions as much as possible at the decreased size. All levels have also received quite a few graphical and color changes.
Let me know what you think and if anyone has better ideas for sprites, please share.
The a78 file can be played in MESS as is. If you want to use Prosystem, you'll need to add these lines to your Prosystem.dat.

Update 15 June 2017:
I probably should have uploaded this a long time ago, but wanted to have all graphic edits done before I uploaded again. As far as I can remember, this is the same as the version 7 ROM, but has a lot more color variations for the enemies. I'd still like to update the leaves graphics in the forest area (not that there's anything wrong with the original ones, but I'd like to make the style match the newer grass), but I don't know when I'll get time to do it, so I'm uploading the latest version which is probably from late September 2016.
Update 5 Sep 2016:
It looks like I chose the wrong ROM last time I updated this thread. Although labeled as "RC7", the last one was not RC7. That has been corrected and it is now available for download below. If you downloaded the last one, please download this one instead. Changes since the last update include a complete re-draw of the player/enemy sprite. I started from scratch, trying to get as close to the arcade as possible in the constraints of the resolution and colors. I'm finally pretty happy and the animation can be seen above. I introduced a bug a while back where the game would crash if you fell down a pit. This has been fixed. Also, the title screen has been updated as well as Missions 1B, 2 and 4. I still haven't done the work I plan to do on the forest level, but I'm pretty much done with the other stages (unless more ideas come).
