After some work(and nearly ruining the gamepad screen because of flickering) I present:

HOLY FUCKING SHIT!
YOU DID IT! :D

Freaking mazing dude! Congrats!
Did you by any chance remove the Gamma correction too?

Would you mind giving the instructions to see if the NES/GBA/N64 RPX also have the settings located in the same address (or similar)? :P
PLEASE! XD

Yeah, gonna write up a guide on how to hex edit it. Didn't look into gamma, but I might :P.

Great!
To be honest, the stretch full screen was the thing that I wanted the most out of the VC emulation, I can live with gamma correction, but hey if you manage to remove the gamma correction or edit it in some form, even better. :P

I'll be on the lookout for your guide and hopefully the same can be applied to N64 VC since I feel that one needs it desperately :)

THANK YOU!

Also, if you haven't already, get a copy of the Cafe SDK. You'll need it :P.

Uh-huh so it involves converting the RPX to ELF, modifying it and then recompiling it as RPX?
Have you seen what changes in HEX does the original RPX have against the aspect ratio modified one?

Perhaps that could save the trouble of going through the conversion process.

Sure, I'll take a look.

Well, it appears there is either compression or encryption on the .rpx files, since they're like 99% different. So that won't work :P.

Ah Nintendo and their damn encryptions. :P
Doesn't matter though, I'll gladly convert and grab that SDK to achieve these wonderful full sreen mode. xD

A Wiiu HD filter like Super Mario Maker on VC Games, is it possible?
Nope.
The_randomizer was talking about turning on/off the Bilinear Filter for VC titles.
It's highly unlikely something like that could be achieved in VC emulation.

The most you can get would be some sort of hq2x/Sal2x filter but I don't think the VC emulators even have such option within.

But I was looking in the GX2 functions and I did see something with the word filter in it.

That explains it. :P

Anyway, here's a basic guide:
Run rpl2elf on the dumped .rpx.
Open the elf in a hex editor and search for 392003563860(hex)
Replace the 0356 part with 0280
Search again for 043838E0078090(hex) and replace the 0438 with 01E0 and the 0780 with 0280
Convert back to rpx by running in the sdk tools folder:
set CAFE_ROOT=../../../
makerpl64 -f -z8 -old -s name.elf

Copy back to sd card and run with loadiine.
Done!
