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

[Sono]

A question about the origin of this amazing hack: Do I understand correctly that the widescreen feature for DS games was already included in the stock firmware for 2DS/3DS by Nintendo, but hidden and not used for some reason, and Sono reverse engineered the code and made it live? That's fantastic...

Widescreen: no
1.5x stretching: yes

I had to completely reverse engineer the driver and do tests using my exe patcher to figure out how to stretch X and Y axes individually.

 

[Sono]

So... @Sono can you make the 32 bit version of the patcher if I can execute as admin?

I actually tried running it, and it crashes before printing ANY text. Sorry :/

Agh, so frustrating. It's horrible being a low end user. Thank you for helping anyways.

Everyone has been waiting long enough. It's 31C at 21:58 and I'm having a heatstroke. Fuck this.

I packaged the secret PC version. No pattern selection, sorry. Not that it's useful because the widescreen patch writes an identity matrix on boot.

Put unpatched TwlBg.cxi or section0.bin next to mkpatch.exe and rename it as section0.bin
Run ./mkpatch.exe asd 1010
That will create TwlBg.cxi which you can copy to your 3DS

The exe is in a zip to bypass "security" checks.

the "asd" part can be anything except "agb"
"1010" is a binary bitmask, 0th bit is rightmost, zerofill
bit list:
0 CTR_Redshift
1 debug text
2 trainer mode
3 DMPGL wide
4 "HID" patch, source code says "remove opposing DPAD check"
7 "DEBUG" patch, source code says "hidden debug patch"

rest of the bits must be zero or else fail

Note for patch selection:
If "bytes used" reports 100% or more then remove either the debug text or the redshift code!

@Sono Thank you my fellow friend from our country. Just a quick question, is it just stretch the game screen or displaying with the right ratio?

Sadly it's fake. I'm just stretching the already existing 256x192 image to 320x240 (or 384x240 for the widescreen patch), kinda like how you would in mspaint (stretch 125% on both sides).

As for the widescreen part, I've been told that the DS-side patches only patch the code so the 3D geometry gets squished, so when you stretch it out it'll look normal, and this is called anamorphic widescreen.

Can confirm. Currently the only squished bits in Pokemon Platinum are the 3d objects

Makes sense, considering that only 3D objects can be squished (with or without a patch).

@Robz8 I managed to get TwlBg.cxi, but I start the game (PkmnHG) and a black screen appears.

If backlight doesn't even turn on then TwlBg.cxi is corrupted or invalid.

If backlight turns on then the patching failed. Is used bytes below 100% ?

Isn't that caused by the anti piracy protection in heart gold and soul silver ?

Wait a minute. My 3DS is all weird. The apps I had on my SD card disappeared and TwilightMenu++ doesn't even start anymore.

I don't think so. Before putting Widescreen.cxi on TwlBg folder, the game started just fine

Noob question: I got it to work, but... Theres this weird codes on the right side of the top screen.

 

[Hyper99]

@Sono @Robz8 Ok, this is really weird. I don't know if this is meant to be like this but it seems TwilightMenu++ deletes Widescreen.cxi and creates a TwlBg.cxi on the luma/sysmodules directory. After booting a game (after I close the app when the black screen appears), TwilightMenu++ doesn't boot after I open it again.

Did you manually install the latest TWLMenu++ CIAs?

Did you use 1010 mask? It sounds like you tried 1110 or 0110, hence the debug text stays on-screen. Is the game even running?

Yeah, yeah, its running good. I guess that my problem is that I dont know how to do that "mask" stuff. I just put the .cxi file in the same folder of the .exe, renamed it, and patched it.

If you run the exe directly then that's what you get. Don't do that.

Place this file next to your "mkpatch_b.exe" and rename the file to just "wide.bat" opposed too "wide.bat.txt" and run the bat file by double-clicking it.

That should give you the proper file

Alternatively..if you want to make your own batch file..put this in it

mkpatch_b asd 1010

Thanketh you for your work, papa Sono
Pokemon Platinum's overworld sprites look crunchy as hell in Widescreen, but 3D looks perfect

The game doesn't boot. And I believe I used 1010, but I asked a friend to patch it for me since I don't have a 64 bit OS. But I just told him to execute the wide.bat (which was correctly written) and send me the TwlBg.cxi
