That positive review was me! :)
Hokay, so this is an old thread, but as we're all lovers of DOS games, and as everything lives forever via Google, I decided to bump this thread so that future visitors will have more info.
First, for those of you who got in under the wire (more on that below) yes, it's quite a good app. It runs nearly everything written for DOS, including Windoze 3.1. The only thing you have to watch out for is memory, but I've had good success with it, both with side-scrolling platformers (think Duke 1&2, Commander Keen) and first-person-perspective RPGs (think Eye of the Beholder, Ishar). Some games (in terms of actual play) work better than others, due to the controls needed to play. For example, Wolfenstein 3D, while completely smooth and playable, doesn't translate very well because of the controls. In landscape mode, you'll see the main screen, the directional control on the left (you can switch between a virtual joystick and D-pad ), and the Alt, Ctrl, Esc, and Enter keys on the right. In vertical mode, all of that moves to the top half of the screen and a keyboard fills the bottom half.
You will need to grab a couple of small files and move them into the Aemula directory on your Fire. More details can be found
right here. You will also need a utility like WinImage to add or change the sample .img file provided in the link above if you want something other than the 4 shareware games provided (Duke Nukem 1, Prince of Persia, Commander Keen 4, and Wolfenstein 3D).
Now, for the "under the wire" bit. Shortly after I wrote that review, the app was removed from the Amazon store. I have no idea why, but last night I was trying to find more info (hence, me coming across this ancient post) and discovered it is still very much active. I have an email out to the dev and will update here when I find out more.
Currently, I am trying out
DOSBox Turbo v142. The shell works great, but I haven't tested games yet, so I'll do that and also update here.
Cheers!
(Edited to fix name of included shareware (Commander Keen 4, not 3 as I had previously stated).)
(Edited again to remove " It does have external joystick support, but I have not tested this, so take that into account." The Joystick button is what toggles the virtual joy pad and d-pad. There is no external joystick support that I can find, but I'll confirm this with the dev.)
