Sono releases TWL patcher with DS(i) Widescreen support

I'm not Sono, but I've done a few of the widescreen cheats for the games on that list. Unfortunately, 2D games are somewhere between extremely difficult and impossible to hack to add widescreen support. They're generally designed around displaying a specific number of tiles, so the "extra" tiles for widescreen just aren't sitting in memory waiting to be displayed. For 3D games it's a different matter, because the 3D world still exists in memory even in the parts that you can't see, so we can adjust the camera to show more of the game. For 2D games, you'll basically just have to keep playing in 4:3.

That's not necessarily correct depending on the engine. By default things that are considered to be off-screen or not visible by the camera are clipped in order to reduce the load, you don't have to bother rendering faces of objects that the user can't see anyway. If they are within the camera's view, they will be rendered correctly, but it's entirely a matter of the implementation of the camera AFAIK. As for tiles, they necessarily have to be stretched because the DS's tile system is hardware-based and very rigid. The tiles and the map are in memory, the tileset and tile map have to be loaded in order for the DS to display anything at all (unless the background is streamed, I suppose), but the DS itself doesn't have enough "room" between the main memory and the screen that it could send them to - the layers are very specific in terms of height and width.

@Foxi4 Yeah, I was speaking in general terms, obviously 3D games cull objects outside of the area that's expected to be on-screen, but 4:3-->16:10 is only a 20% jump, so we don't encounter much of an issue there. For our purposes, culling isn't a major concern.

Oh, I was merely posting an addendum to what you've said, I don't think anyone would be particularly bothered by very minor glitching at the edges of the screen in select few games if what you get in return is proper widescreen support.

That’s fucking amazing, I’ll definitely try it today! Although I must ask, would this work if I played games from a flashcart? In particular I have an r4i gold 3DS RTS. Shows up as qmaterial on 3DS home screen.

I wonder what comes next... maybe DS(i) games at native resolution (or even better, DSi enhanced ROMs). I seriously hope that happens soon, the 3DS hacking scene amazes me even today.

@Alex4nder001 Replacing TwlBg with a widescreen patched one will affect how everything that runs in DS mode looks--retail cards, flash cards, DSiWare, DSi homebrew, etc. So it will stretch your DS mode stuff out to 384*240, but if you want to actually run games in widescreen (rather than stretched 4:3), you'll have to put in a bit more work. Using an app like R4CCE (R4 Cheat Code Editor) you'll need to add the widescreen cheats from the link in the first post to your usrcheat.dat file on the R4, then enable them in the flash card's menu.

Finally, I can now play High School Musical in WIDESCREEN!!!!!

On the other hand, I don't see Super Princess Peach. I'd like to replay that game and complete it once again.

Only 3D data can be squished, 2D squishing is almost impossible due to the DS "GPU"'s limited support of 2D transition.

Also I haven't been keeping up with the 3DS scene for quite some time now. Is it now possible to play DS games installed to the menu and run at full speed, not using a flashcart? If so I might want to try this out on that.

YUP

most games at least

Incredible! I might buy 3ds again just for this

Alex4nder001 · Aug 13, 2019

I've tried it, works pretty well but when I hold START/SELECT the screen gets really derped and a lot of the screen is missing.

You would need to put the resulting file in \luma\sysmodules, but it will stretch every game, making the games without the widescreen cheat support look stretched only.

YuseiFD · Aug 31, 2019

Yeah this feature doesn't work at all, pokémon platinum is still stretched, even with cheat code on, and stock backup from my cartridge, upfated to latest version even, well it was a great idea anyways, keep up the good work buddy
