Wow, great. It actually manages full speed unlike VBA GX. I still don't have any use in emulators on the Cube but it's great that this exists.

To my test, The speed is great (framerate keeps 59.94 for most games); 32MB ROM such as Mother 3 would not run; No buttons remapping available.
It is very promising for early release.

ROMs are loaded into ARAM, so only up to 16MB is supported unless an expansion device is designed as discussed on IRC.

It'd just happen to work right now if you had one, it's possible to solve this through other means.

I got several questions for this release:

1) What is the changelog between this version and the official mGBA port?
2) Is the source code for this project (EmGBA) keeping up with the changes that the official mGBA nightlies are implementing?
Or is it based on a certain nightly?
3) Does this have button mapping and filter options?

How do you make a changelog between independent ports?
ShadowOne333 wrote:2) Is the source code for this project (EmGBA) keeping up with the changes that the official mGBA nightlies are implementing?

At the moment, it's based on the Git master at the time of release.
ShadowOne333 wrote:3) Does this have button mapping and filter options?
No button mapping, refer to Game Boy Interface's documentation for options.

meta.xml example:

Code: Select all

	<arguments>
		<arg>--filter=scale2x</arg>
		<arg>--input-gamma=2.2</arg>
	</arguments>

  • Changed "no filter" to really mean "no filter". The default is now called NormalNx.
This addresses one of the_randomizer's concerns.

Got two more questions:

1) Seeing how screen size has been added to Configurations, would it be too much to add the most used arguments in there too?
2) If I want to make the game to fill the entire screen, which option should I set?
--aspect=16:9?

Maybe.

You'd set the aspect ratio to be the same as the GBA's, 3:2.
You'll likely need to set a custom zoom level as well.

Extrems,

First I would like to thank you for the extraordinary job with GBI and now this.
They are the best ways to play GBA on a big screen.

I think that the only thing missing with this emulator is to display in 240p.
I have my GC connected to a Sony PVM and with GBI ULL it looks amazing in 240p with real scanlines.

It would be nice to get that look with mGBA.


Cheers

I used aspect ratio 3:2 and set --zoom=3.
That was the best I could get. :P

Although, it still doesn't fit the whole screen with "normal" and with "full" the zoom goes way beyond the limitation of the screen.
I also tried setting it to --zoom=2 but it won't fit even with "full" configuration.

I saw that the argument listed in the Gameboy Interface thread is "--zoom=f"
Is there any other config for zoom that I'm missing?

You need to set it back to default screen mode, normal/full is an algorithm and your setting won't take effect.

  • Added stretch screen mode.
  • Added saturation intent.
I don't know why you'd use Enhanced mGBA only to undo my work, but now you can!

With and without arguments I get a code dump when exiting, but only if a rom has been loaded.

I also wanted to ask, what do think about an auto boot option? Like send an argument to the rom's path and also exit directly without going through the file browser first. I also want to say thanks, oversampling is a dream come true.

Sounds like you're using the real BIOS. I wouldn't recommend doing so at this time, it also break savestates.

It's on my list.
