Hacking Widescreen cheats for DS games on 3DS

[RocketRobz]

I put the Heartgold Widescreen code in TWLMenu++ but it doesn't work. Anyway to fix it?

Just wait for the next version of TWiLight Menu++ and TWPatch (by Sono) to be released.
Next TWLMenu++ version will include the code.

Alright, thanks!

Can't wait to play DS games in Widescreen in the 3DS!

I don't know if it too much to ask, but a code for Final Fantasy 4 Heroes of Light would be really neat

I actually made one for this game a couple of weeks ago but didn't post it because it seemed relatively unsatisfying (overworld gameplay is all on the touch screen but battles are on the top screen). If you don't mind that most of the game won't actually be in widescreen I'll give it another look.

EDIT: I worked a bit more on the 4 Heroes code so now in addition to battles, it also affects the character naming/inventory/ability menus. I've never played this one, so I'm not sure if there's anything else to widescreen. It's been added to the OP. Hopefully better than nothing.

EDIT2: So you can expect something like this:

Whoa, it looks incredible!
Thank you so much for this!

@Pedroverri If you do prefer to play in full dual-screen widescreen via an emulator, I just added a quick bonus code to the first post (Bonus spoiler at the bottom) which widescreens the overworld as well:

Boy, that is beautiful! Kinda makes me want for some HD re-releases of DS games.
But this is the closer I will get for now, thank you for that!

How do you tests those cheats if sono's patch is no already yet? Are you using a emulator to test the functionality?

 

[The Real Jdbye]

Nice idea. Why 16:10 though? Why not 400x240 and make use of the entire screen?

Yes, and also, Sono gave me access to his private GitHub for the patcher, so I got a widescreen TwlBg, as a result.

The matrix hardware doesn't allow full scaling to fit the entire screen.

They have access to the manual patcher, but it's not usable by any user due to having to compile it from source.

Because you have to select a scale ratio from n/d where n and d [1; 8]

Edit: got ninja'd

You already got several answers to this, but one more since this part wasn't covered: the cheats technically "work" even without Sono's widescreen patch for TwlBg, so it's entirely possible to test them, even on hardware, without actually having a way to display the games in widescreen. The result is similar to setting a Wii to "widescreen" mode on an old 4:3 TV. Everything will work just fine, but you're displaying in the wrong aspect ratio because your TV isn't widescreen. Without the widescreen patch, these codes basically create a sort of ... squishscreen, which is ready to be stretched back out by a widescreen TwlBg as soon as that becomes available.

Nice work! I just tested this on hardware (I swapped your 32-bit read/writes (codetypes 5/0) for 16-bit (codetypes 9/1) and the code works, but this game varies which screen is displaying 3D throughout gameplay, so unfortunately for 3DS users, it needs a more advanced code like Diddy Kong Racing. I've added it to the OP under the issues section.
