the hype is real-
Widescreen Action Replay Code List
IMPORTANT, The following codes are accurate formula's but don't accept decimal spaces, so they will be slightly off but not noticably.
Crafting your own Widescreen Code! If you want to try craft your own code for any game not listed, you need to know a bit of debugging first, the following is not a noob-proof or in depth tutorial.
One method is to use DeSmuME's RAM Searcher to search for the value of 1555 (HEX) or 5461 (DEC) and just trial and error of changing them to 1C71 (16:9) until one works.
If you find out which one works, take its address (which should start with 02) and simply follow the following format, test it, and if it works, good job! Let us know your code and what game and i'll add it to the list.
Format:
<Address but change starting 02 with 52> 00001555
<Address with starting 02> 00001C71
D2000000 00000000
While it will just work with the Address and the value of whatever aspect ratio you want, it will be applied every frame even when it may not be in use (Thanks @KazoWAR for the tip)
The first and third line essentially just does a pre-check before trying to overwrite them.
If you're confused by the format, just take a look at the below codes as an example. Code List:
  • Mario Kart DS (In race only) 520775D0 00001555
    020775D0 00001C71

i was wondering when people would figure this out :P i sorta invented the whole widescreen codes on DS back in 2011 starting with mkds and this code 12147e04 00003D30 and later this 020775D0 00001C71. mid last year i had discovered thats the widescreen value was universal with most ds games. but not all of them. heck even homebrews like dscraft have the 00001555 value. so heres a complete list of games that ive made the widescreen codes for. ive been working on them and quietly releasing them via deadskullzjr cheat code data base for NDS which can be found on this site.

There all verified fully functional by me. a few ds games used slightly different values for example animal crossing had 1548 instead of 1555. wile others require pointer codes. i noticed looking some of the codes above that people had already posted will not work on the entire game with out a pointer. and yeah i know some of the codes below are already posted i didn't feel like fishing them out.

Link is wrong in your tool, it redirect to a 404 and fail to download
1561065780-desktop.png


--------------------- MERGED ---------------------------

And your link is ok but doesn't contain any release/artifact (or I don't see a download link...).

Ok odd, the link in the app is a bit broken, but the internal code itself should work, regardless, its failing because there is no artifact like you said theres none to download, they delete them after x days of the build being done I think :/

--------------------- MERGED ---------------------------

It's possible to do something like this on 3DS? D:
I wish ;-;, Ages back there was an april fools of someone doing it on MKDS, it was cool, but yeah I don't think this would be possible without a complete edit to NTR stuff

Same problem here...
There is not a way to do it anyway?

With the program failing to download a new copy (since the latest build on Appveyor failed). Is there a way to get this program to see a copy of Desmume downloaded manually?

They do not delete builds, the latest build for desmume has failed to compile which is why it's a 404. I'd suggest looking through their api documentation to see if they have a link for the history and parse through that instead.

Go to the AppVeyor for DeSmuME and download it from the build history.

Just wanted to mention that this formula multiplies by 100 then divides by 100; that part of the formula isn't actually doing anything. Really it's just:

oAH / oAW * oD * cAW / cAH

None of the parentheses are actually necessary either because all of the operations are division or multiplication, so the result is the same regardless of what order you do them in.
