Homebrew TWPatcher - DS(i) mode screen filters and patches

[Deleted User]

Very cool thing, although, honestly, after examining all the filters for myself, I find that Nintendo's default seems to look the best anyway.

Its a give take

After messing around with the filters a bit. Battle sprites in Pokemon seem to be a lot more crisp

On the other hand though text seems to get a bit blurry

IMO Nintendo's looks blurry, washed out pale colors, and noticeable artifacts in 2d images

Hype for Widescreen

Welp... it turns out I triggered some anti- buffer-overflow code in the kernel, which caused it to intentionally crash to prevent any "accidental" attacks against its code loader. And I tested, and the patcher works, yay!

Spoiler: Please read before downloading

Code compression takes a whopping 6minutes on old3DS, so make sure you only press START when you're really sure you selected the right kernel. On new3DS it should be slightly faster.

The code uses pure CPU rendering due to full-blown matrix hardware emulation, so it's going to be awfully slow, and thus unresponsive. YOU HAVE TO HOLD THE BUTTONS INSTEAD OF JUST TAPPING THEM.

The menu disappears after a few seconds if you don't press any buttons. This is intentional, so you can see the result on BOTH the top AND bottom screens.
You can keep the menu up by holding LEFT or RIGHT.

Keep holding X to temporarily switch to Nintendo's default filter. Releasing X will switch it back to the highlighted one. You can use this to check the scaling mode back and forth for visible comparison before applying.

I accidently broke the ability to switch out test images with the Y button, so I removed it for this release, because I already wasted a lot of time with the compressor. If I won't forget to fix it then the next release will allow you to switch test images with Y.

Once you press START there is no going back. You can only cancel the compression by holding down the power button. DO NOT CANCEL WHEN THERE IS A SMALL AMOUNT LEFT!

Hold SELECT to exit.

Actually not. I hope you read the above, because it contains important information!

You didn't read, did you?

Maybe there is also the possibility of enabling this for GBA games?

Yes. Someone asked it on reddit, and my reply was that it will take a month or so more because I'd have to reverse engineer AgbBg again, because appearently it's slightly different from TwlBg.

 

[Feffe]

Great work, I'm testing the different options now.

@Sono Unrelated to this, but would it be possible to hack TWL_Firm to remap 3DS buttons? (Would be usefull to have a dual analog setup for Metroid Hunters on New 3DS). (Also man, get some sleep, really - I have been lots of sleep problems in the last months and it's awful. Be careful)

I highly doubt it's possible. I'm pretty sure the buttons are hooked up directly to the DS CPUs, so ARM11 can't intercept them.

@Robz8 will you be adding a widescreen option for TWLMenu's UI itself? Perhaps support multiple CXIs to have per-game filter setups?

@Robz8 will you be adding a widescreen option onto TWLMenu's UI itself? Perhaps support multiple CXIs to have per-game filter setups?

Yes, a widescreen option will be added.
Also, multiple CXI support would make the compression process longer.

This is neat! I assume widescreen is coming Soon?

Cannot wait for the Wide Screen!! than I can finally enjoy my ol NDS games again. Really hate the screen cut on the 3DS

 

[xXPVTSnowBallXx]

So far so good, loving that my n3dsxl doesnt look so bad for ds games now! I couldnt be more thankful, only issue im having is with pokemon soul silver and platinum have this weird mirroring/ tearing on the bottom and side if the screen, anyone else experiencing that?

Could you also unlock more RAM for DS mode?

That has to be done from the ARM9 side, and I don't know anything about the DSi yet.

 

[Vague Rant]

With apologies for yet another feature request, @Sono, do you think it would be possible to re-enable the third scaling setting (the 1.5x scaling) and put that on another button, e.g. hold R while DS mode starts? I don't actually think anybody would want to use it for the 1.5x scale, but it would allow users to have three scaling settings in a single TwlBg, e.g. Linear sharp 1 (default), Pixel Perfect (Start or Select), Linear sharp 1 widescreen (R button).

Paging Robz8 also: would TWiLight Menu++ be able to programmatically trigger a specific filter in this way, or is switching to another TwlBg.cxi the only way that can be done?

Not enough code space, sorry.

Just download some more n00b.
