thanks worked like a charm! removing the plastic snap on (orzly) gets easier every time but still a PITA.
1) can you eli5 why this feature isn't baked in and has to be manually done with that .exe and .bat to make the magic happen?
2) also more important, its 'normal' to see a quick graphical glitch on right side of screen booting up a game (someone screenshotted it, but I don't see it when the game actually loads) . not sure if all or just some titles, just started playing/testing
Looks great so far from a quick glance!
I'm not Robz, but afaik, the widescreen feature consists of two parts.
First, there is a patch for TWL_FIRM. TWL_FIRM is the part of the 3DS's OS, that handles DS/i games. Sono researched TWL_FIRM to find out, how to modify the filter it applies to DS/i games to make them fill the screen.
When you launch DS/i games normally on any 3DS, they get stretched by a non-integer value, to fill the screen, and blurred, so you can't see, that the pixels aren't stretched equally. Sono looked into that matter and found out how to apply several different effects to DS/i games by patching TWL_FIRM, the part of the 3DS's OS.
That means: Step one is to stretch the output of TWL_FIRM, which is done by "that .exe and .bat magic" on a computer, since you have to directly patch a file from the 3DS's OS, which apparently can't be done that easily on the 3DS itself.
Step two is applying a cheat to a game to squish the video output, which actually is baked into TWL Menu++. The output needs to be squished, because TWL_FIRM stretches it out again, which makes the game look normal again, for the most part.
I hope, that the stuff I said was correct, since I didn't read Sono's thread about the TWL_FIRM widescreen patch itself, so feel free to correct mean, if I'm wrong.
I also hope, that you now know why patching TWL_FIRM isn't baked into TWL Menu++.
