Hacking Understanding and changing Snes VC RPX settings

[ShadowOne333]

Ugh, that's what I was afraid of, Nintendo's emulators must be really bad then.

Not bad, we simply don't know how to use them properly yet

I mean, games that run, run well, but others, have weird sound glitches and the colors are dark; Paper Mario looks really squished unless you use that config file provided earlier in this thread Just wish games like Jet Force Gemini would boot up, Banjo Tooie, etc, you know?

I guess it is finally done. The Harvest Moon 64 ini is on the rar and attached is the rom byteswapping tool needed for the US N64 rom, which you will need to get somewhere else.
Ini includes the CRC of byteswapped working rom, latest vessel (2428 TIME: 2016/11/18) you get from F-Zero X.
StickLimit = 64 worked best for me, but it still doesn't compare to the real 64 since VC stick range is pretty crap.

Replace Vessel in sysnand ?

Why would you even need a byteswapper? Unless you get v64 roms, there is no need to do that.

Most roms i have are v64.

I got in contact with a friend of mine, @Lorenzooone, regarding the N64 resolution, asked him if he could help me out to locate the code that "might" be in charge of setting the resolution, and he found this:

.text:02003F6C li r0, 0x280
.text:02003F70 li r10, 0x1E0

That's the equivalent of 640x480.
Just look for these bytes in the VESSEL.ELF file

[38 00 02 80 39 40 01 E0]

and change it for this:
[38 00 05 00 39 40 02 D0]

That should hopefully change it to 1280x720, although I am not sure if it does or not since I am at work and won't be able to test it until maybe tomorrow with luck. Could someone give it a try?

Just remember that you need to convert the VESSEL.RPX file into ELF first, open a HEX editor, look for those bytes and change them, and then encrypt the ELF file back to RPX.

The game continued with the same resolution.

The game continued with the same resolution.

Oh damn, really? :/
Damn this crap.
Can someone else confirm this?
Also, could someone tell me what is the exact resolution the N64 VC uses?
Maybe I was going for the wrong res, I tought it was 640x480

1080p is default i guess, 720p with bForce720p = true.
Remeber it is 4:3, so max must be 1440x1080.

Edit:
GX2_TV_RENDER_1080, 1440 x 1080
bForce720P..GX2_TV_RENDER_720, 960 x 720

 

[ShadowOne333]

1080p is default i guess, 720p with bForce720p = true.

Oh, sorry, I meant aspect ratio.
I know the desired one in this case is 1280x720 for fullscreen, but I'm unsure what the actual VC is using for N64 games.
Is it 640x480?
I ask because this might be key to finding the correct value on the ELF file.

 

[Pachee]

Not of much use, but i found something. The predefined video modes on the vessel are all already filling the whole screen area, and then something else renders the game screen on top for that, keeping the proper aspect ratio.
You can notice this by pressing the vc menu key, it will fade in while zooming out the game, on exit it fades out while zooming back the game.

Yeah I did notice that too.
Maybe that can be changed in one config file of some sort instead of the vessel itself.

Urgh, it was a pain to finally get a working rpx of this vessel. wiiurpxtool is setting some wrong byte somewhere and generating a broken file.
Edited the alpha of something from 255 to 2, dunno what.

What rpx were you looking for?

 

[JohnathanMonkey]

Is there documentation somewhere that identifies what everything is inside the N64 ini?

 

[AlanLC]

Is there any way to use cheat?

Open the elf in a hex editor Search for 043838E0078090(hex) and replace the 0780 with 095F (NES) TV
Open the elf in a hex editor Search for 392003563860(hex) and replace the 0356 with 0429 (NES) Wii U Game Pad

Open the elf in a hex editor Search for 043838E0078090(hex) and replace the 0780 with 08C0 (SNES) TV

What about the parameter for (SNES) Wii U Game Pad?
Or this string(043838E0078090(hex) and replace the 0780 with 08C0) will affect on game pad screen too?
I see for NES it is two different parameters.

I'm really not finding the hex value you posted, either of them. They don't show up on my hex editor. I'm using hxd and i am searching hex not anything else.
EDIT: Nvm the hex is a little different for certain games its trickier to find but i got it
