It will work if you decrypt the file, but it is easier to use the R4DS cheat editor: http://www.r4ds.cn/download/Cheat_code_editor.html
oh yea, the R4DS is the best thing you will buy, well not really. But it's great, you'll save sooooo much money by buying it. But if you want to put in more memory you should but the CycloDS because it supports up to 8gb while the R4 supports only up to 2gb.
sandisk 8gb 4gb 2gb yes it does work
The related link is how the White R4 looks like, the image being from the R4DS website. The black R4DS has only the colour changed, with no extra letters or pictures on the label. Also, the newest versions of the R4DS firmware won't work on fake versions of the R4.
yep
The R4DS does not support any microSD cards over 2gb. So, sorry, you bought that for nothing. And there is absolutely no way to get it to work so don't bother.
no, but there is no need to, the R4DS has a built in Action Replay.
No it is illegal
Yes the r4ds boots up game boy games into ds mode.
