1. Downloaded rom- could be a bad rip or maybe a someone didn't upload it correctly. The best fix is to dump your own NDS cart. Failing that find a different download.

2. The 3-5 times may be an implemented feature of the demo version of drastic. Would need exophase or Lordis to coment on that one to be honest.

3. Unless you are really really hurting for hard drive space on your phone/tablet it is a good idea to unzip/7zip/rar/.... your roms or don't zip your roms you legally obtain from your own NDS carts in the first place.

4. While your post is longer then some if you want any more detailed help then what I have given you please include your device (phone/tablet), your cpu (there are some wonderful apps like cpu-z that will tell you which one you have), if the crash happens in a specefic spot a savestate at or right before that spot is also helpful. List of settings couldn't hurt either.

Hope some or all of this simple advice is helpful to you and or others

You might want to check the file type. You want the bare .nds file, and a .zip file is the easiest to get the game out of- just open the folder and rip the game out. But other file types are real buggers. For example, 7-zip files are very common, and very hard to get the game out. RAR files are even tougher, and both require the 7-zip file manager to get the game out (and it takes FOREVER). I have found a loophole- the B1 Archiver (http://online.b1.org/online), which runs entirely in-browser and gets the game out.
