Homebrew Emulation GameYob, a gameboy emulator for DS

[Topaz2364]

This is very strange.
Ok pal... Still trying to help.
First: Delete the gbc_bios.bin from the line: biosfile=/roms/Gameboy/gbc_bios.bin and you should get: biosfile=/roms/Gameboy/
and try again.

If this doesn't work, then I don't know what might be causing your troubles.
Delete Gameyob from your DSi (if you're using a flashcard just delete the homebre file) and all related files to Gameyob, except your roms.
Download the bios files again, and make sure they're the good ones. I can't give links... but making a quick search and clicking on a wowsite will do.
Set the files on the gameyob.ini for your roms, and set the same path for your bios file.

ill just stick with black and white i guess, (also i was using CFW and TwilightMenu++ on my dsi) at least i have borders i can use, thanks for trying to help though

Is just that I've noticed that on the bios path, you're directing the bios to the bios itself when it should be directed to the folder and not to the file.
So delete the gbc_bios.bin from the Bios path and it should work.

i did that, and it didnt work

Ok then... I give up. Like literally don't know what else might be causing your trouble (deja-vu!)
Maybe is your CFW, but who knows... is certainly strange.

Hope you can find the solution.

To be honest I was just looking at my Gameyob folder backed up on my external hard drive, and I noticed that I don't have a Gameyob.ini

But I do remember using bios files with Gameyob (or was it Lameboy instead?)
I truly mean that the last time I used Gameyob (or Lameboy, can't remember) was around 2015.

I understand completely, this emulator is 7 years old and it can be tricky trying to get things to work properly, but ill stick with B&W graphics until GoombaColor works with the gba emulator

Why u want to run a emu inside a emu?

@Shadow#1

@Topaz2364 dude, try with a flashcard instead.

 

[Topaz2364]

Why u want to run a emu inside a emu?

because then it would be a better solution than using gameyob

lmao, i used to have one, but it broke

And on that note mGBA is a better emu for GB/GBC on 3ds

Very true, its flawless when it comes to gb\gbc

Not at all, 2x upscaling option puts Gameyob waay ahead of any other while mGBA only have linear and nearest looking blurry and glitchy respectively...

They are planning to put (probably, it is in their forum for 9.0 ver) hardware acceleration for 3DS so at that time the aesthetics (the x2 upscaling of gameyob3DS) will probably be left aside in favor of being able to decently emulate everything, try to run Pocket Bomberman in mGBA with an O3DS, horrible, Gameyob runs it well even on DSi.

From twilightmenu++ you need to "exit" from the gb game to the menu of gameyob, then select the game again, now you can see the bios and select the color you want.

The better choice is using gameyob from hiyacfw, the bios is detected at the beginning

some gbs do not work, but gbs2gb can be used.

Hi everyone, I've managed to change the black and white palette of GB games into the green one that is used by Lameboy.

If someone wants to try to change the palette here's how I have done it: there is a section in the file gbgfx.cpp (in the folder arm9/source) that goes from line 582 to line 605 where the values of the color for both the sprites and the background are initialized. From my understanding one color is made up by two variables so, for example, you can change the first background color by changing the combination of the variables bgPaletteData 0 and 1. In order to generate the desired color you need to convert it from the most used 24 bit notation to the one used by gameboy color and nintendo ds: 15 bit. A useful tool is the one wrote by budmelvin, just google budmelvin 15 bit converter (I'm not allowed to post links).
However, if you use that tool you may need to write the last 2 digits of the color code before the first 2 because it seems that the order used in the gbgfx.cpp file is the little-endian. (Quick example: if you want to write the color 0x6BFC you need to set the variables bgPaletteData[0] to 0xfc and bgPaletteData[1] to 0x6b).
Once you have chosen the desired palette open the terminal, move to the Gameyob folder and type make to make the nds file (you need to have devkitARM installed).

So far I haven’t found any issue caused by the changes that I’ve made, but I’m certainly not an expert and I don’t guarantee anything.

Anyway, here is the compressed file with both the gameyob.nds file with the green palette for the Game boy games and the folder with the files used to built it.

Will this work on 0.5? I can't use either 0.5.1 or 0.5.2 on my R4 because the reset homebrew hotkeys stopped working? I noticed that you had copies of the older builds in your zip. I didn't report this as a bug and doing so I doubt it'd get fixed anyway as it's an old emulator and Drenn doesn't do anything nowadays.

So does this emulator have any option to display the Gameboy Color bios intro? I have the bios file with the correct path in my INI file and the emulator sees it, but it seems to skip the splash screen.

It only displays the Game Boy bios intro if you enable it to use it.

Yeah I think that this will work on 0.5 as well, the gbgfx.cpp file seems to have the same section in both 0.5 and 0.5.2. Can you please tell me why do you think that I have copies of older builds in my zip file? From what I remember I downloaded the 0.5.2, changed the values of the palette data and created the .nds file. However, I noticed that in the 0.5.2 the README file has "GameYob v0.5" written in the first line for some reasons.
Anyway, link me the source code of the version that you use and I'll see what I can do about it. Keep in mind that I'm still not an expert, I tried to change the palette just because I was bored af during quarantine lol

I'm not a programmer and am just a user. I use the existing versions out there.

Why does the audio crackle in all of the Zelda games? I've tried hard formatting my SD card and I've also played around with all the settings and nothing, there's still audio crackling on the Zelda games.

I've tried it on my DSi, DSi XL and new 3DS and the problem is the same for all of them.

Version 0.3 didn't had this problem I believe. Also audio is perfect when using Lameboy.
