I've tried every combination I can think of, M2 is still black and white. Other games like kirby 2 show in color...

Well the thing is. Metroid 2 wasn't programmed to have color. But the gameboy color has hard-coded palettes for some games, including metroid 2. To take advantage of this you need to download the gameboy color bios from someplace else. Move gbc_bios.bin to the rom directory, as described in the first post, make sure the bios is enabled, and you'll see the gameboy logo when you start up a game. You can use button combinations to try some other palettes, too.

Okay so you're the second person to mention a problem with the bios. I have no such problems... metroid II works with the bios enabled... can you confirm that it works with bgb or some other bios-compatible emulator? And, to be sure, you're not using the metroid II color hack are you?.

oh i c
its non-hack and hacked ver
Metroid 2 color doesn't load with bios
i use Visualboy Advance
to see if it works with bios but doesn't
so to play it on gameyob without bios

Metroid 2 non-hack works fine
on both computer emulators and gameyob with bios or without
:3

sorry my english is not my first language if i didn't make sense then im sorry D:

btw im using Supercard dstwo for the emulator :3

So the SGB mode doesn't work like an actual SGB with metroid?

Technically, Metroid II is not super gameboy compatible, so SGB mode does nothing. Nor is it Gameboy Color compatible. But both GBC and SGB can provide limited colorization for black and white games. Again, you need the gameboy color bios to do this.

This is what I'm after


Okay well you can't play with super gameboy colors yet. Custom palettes are on the todo list, and when they're done you can make it whatever color you want.

However. What I'm trying to say is you can play with Gameboy Color colorization which is usually better than Super Gameboy colorization anyway.
Google for the gameboy color bios (or, more accurately, "gameboy color boot rom").
Download and place in your rom directory.
Enable the bios in gameyob's settings.
Reset and play in glorious color.

Not that I'm complaining, but are there any plans to revamp the menu, make it more aesthetically pleasing?

So, I had been using LameBoy before switching to this emulator, and for some reason, it keeps using the ROM folder I had made for LameBoy instead of the one I want to use for this one. Every time I want to play a game, I have to switch folders over to the correct one. Is there a way to make it look in a different folder by default?

There's a "rompath" option in gameyob.ini. I've been meaning to make it remember the last used directory but I haven't gotten around to it.

Yeah maybe, it wasn't so bad in the beginning, but it's gotten really clunky now that there are a lot of options. Though I'm not really worried about how it looks, just how it acts.

Wow I love you lol. Not sure why I got the sudden urge to emulate gameboy on the ds but you are a life saver. One thing I noticed though was the pikachu title screen cry sounded a little distorted,but you may already be aware of this. Doesn't bother me at all though. I appreciate the work you've put into this emulator very much :D

Nvm, I used the pcm sound fix and it worked out great haha. You're amazing :P

If you do add the last used directory feature, please have a way to turn it off. (even a on/off line in the ini would be sufficient.)
Due to the amount of gbx roms, I have each letter in its own directory. nesDS has the last used directory feature, and everytime I turn on the emu, Im in the C folder, or S folder, etc etc.

K, so I just decided to start using this...how do I stretch the screen, and how do I turn off the bottom screen display? Hmm, okay the fps/time display is off, but it looks like it's still using power...?

Also how do I exit back to firmware?

Thanks very much to keep this going, actually I don't have enough time to test the latest experimental version, by the way I use to read this thread everyday :).


I am very happy that now we have a GBC/GB emulator that really works:nds: , and that is not in the graveyard.:gun:

L+R+Start+Select exits to firmware.
Scaling can be used in newer builds (binary in the first post) and it'll be in the next release. It also disables the other screen properly.

Whenever I use cheats for a game, they only work for the first game I load on the emulator. If I load another game, the cheats stop working. So I have to re-launch the emulator everytime I want use cheats for a new game. Could you fix this so you can use cheats without having to re-load the emulator?

P.S. Any improvments or plans to improve the compatibility for the Ni-fi? Or will that worked on when the right time comes?

Found a bug!

I was playing a version of Metroid II, with a special hack to add a color palette to the game. (Yes, it's a ROM hack, but that's not what screwed up) I was shortly before the point where you fight the first Gamma Metroid, when the sound bugged out and just made a long steady humming sound. I figured it was part of playing a ROM hack, turned down the volume, and moved on. It's done that before, and stops when I restart the game.

Now, here's the problem. Since this game's built-in save feature doesn't seem to work, I've been using save-states to keep my progress. However, when I hit the "R" button to access the menu and save the game, the menu never came. The game itself paused and switch back to its normal scaled size from what I had it changed to. (I don't know why, but the scaling and filters look much better on this than on LameBoy. Good job on that!) However, the actual menu never came up. I thought for a moment that since everything else was working properly, maybe the menu just wasn't displaying, so I went through the motions to make a save-state and then load it just to make sure, but nothing happened. The emulator went through the process of setting up the menu and pausing the game to allow access to it, but it never actually allowed me to use it.

Any idea what's going on? I don't know if I can replicate it. I haven't tried, and I wasn't doing anything in particular other than playing the game normally, so I don't know what exactly I did to set it off, to try and do it again.

The emulator does this to me on "dragon warrior monsters2 gobi's quest",as well.hope this is fixed soon.
