    NOTE: This emulator is based off of 8086tiny, all I've done is make it run on a 3DS. If you want to see the source code, go there because it's the same besides about 10-15 lines of code. :P

    So, I've decided to put out my latest project: "3DOS", a port of 8086tiny to the 3DS.

    It's "functional", but it doesn't have input support(*should* be fairly easy to do) and only supports text mode(which is strange at times due to the terminal output for the 3DS/ctrulib not having "ANSI escape?", which I think 8086tiny uses for some printing. If anyone knows how to convert this to just ASCII or whatever, let me know :P), but graphics are supported using SDL, so it shouldn't be too hard make that work.

    I've attached a copy of the emulator, along with the bios file for it and a copy of freeDOS, which will make it to the command prompt, but you can't input anything.

    if the source is available you should take a look at DSX86 Its basically a DOS Emulator for the Nintendo DS

    EDIT: http://dsx86.patrickaalto.com/ Here's the website although I couldn't find any "source code" downloads

    8086 tiny plus has MCGA support. I think it doesn't use the ANSI console either.

    Lol thanks!

    Also, I figured I should mention: Try out different disk images, and let me know if they boot or not. I *might* make a tutorial later about how to make one, but for now, google is your friend :P

    Haha you're welcome! I've never used 8086tiny (DOSBOX user), so I'll have to look into it when I have more free time. :P I will be EXTREMELY happy to be able to play Out of This World after 3DOS has some time worked on!

    Cool! I'm actually probably gonna work on the input now, so I'll let you know how that goes.

    Also, a "disk image" is the fd.img supplied in the zip. :D

    Alrighty! Well, MS-DOS 6.22 is going to be tested. Also, when you get input working, do you think you could have it mount a C: drive in a folder at the root of the SD card by chance at startup by default? So maybe whenever someone starts 3DOS, the C: drive will be in SD://3DOS/ I'm planning on attempting to install Windows 3.1, or at least run the installer, for the giggles. :P

    EDIT: MS-DOS boots! Gives an XMS driver error, but it boots. :P

    Cool! Also, sadly, due to how 8086Tiny works, there is no way to "mount", everything is a disk image. I could make a 3DS folder to .img converter, which it will load by default.

    Nice! Also, testing the first version of input right now!

    Also, if you want to load custom programs to test, use WinImage to make a img.

    Yeah. 95 can run on a potato, if at least it can display on the top screen and have a virtual keyboard, and the slide pad doubling as a mouse, that'd be really neat to see.

    So, input is somewhat working! Currently, directions on the Dpad can be pressed, up = d, right = i, down = r, and start = enter. So, by pressing up, right, down, start, the directory listing is displayed. I'll have a video of this up later, as well as a .3DSX, but for now, take this image, I'm going to sleep :P:[​IMG]
