Very nice emulator, and it is smart enough to support the same save file behavior as Lameboy, so I can use my SD at home on the cube, and take it on the go with my DS, if only GoombaColor (integrated in the Supercard) would be as smart!
Still have to check if seamless saving can be achieved with GBA games on the SuperCard. (Would be nice if someone can test it with GB/GBA everdrives too)

I've read multi-player cannot be achieved with GBA core, for whatever reason. But what about the GB/GBC core, I'm convinced the GC can handle four at the same time, so can't we have a GBC emulator running four-player carts with link-emulation on one cube?

The Windows version has the lockAspectRatio = 0...
I think this function only removes the black bars in GBA mode at Full. The Strech mode would not be necessary.

I also think that Game Boy games are running in Super Game Boy mode. You could implement the options to choose from modes. How to start Super Game Boy games in Game Boy mode. Thanks.

Hey Extrems! I caught the new release (May 26th) on a Brazilian website dedicated to Wii stuff, and I am glad this is being updated! But I also found some issues here. The top portion of the screen makes some sprites weird on some games. I was able to take a few pics of Super Mario Advance 2 using my phone, so you can see what I mean:

It really depends on the graphic being displayed actually, but once a sprite gets up on those top lines, it gets screwed:

Megaman Zero is another game where it's easy to spot the issue, but it was harder to take pics of it, so I didn't XD. The previous version, from April, didn't have this problem, though. Have you updated the core with the latest mGBA release? I'll try that out later, too (but I still prefer Enhanced mGBA XD).

TheDimensioner, brasileiro aqui também.
Desculpe a resposta tardia, geralmente recebo um e-mail quando tem alguma atualização por aqui, mas dessa vez não foi XD. Mas bom saber que tem mais BR por aqui também XD!

Hm, then I'll test their release, and if it has the same issue, I'll direct the problem on their forum XD.

EDIT: I ended up not testing the main mGBA branch 'cause I got too hooked on Metroid - Zero Mission, that at least had no issues whatsoever XD. But I just confirmed that the latest release of EmGBA (June 3rd 2019) fixed the sprite issues. Thanks!

Even disabling the Super Game Boy function, games are not yet using the border space. In this case, could you enable the border of the Game Boy Color? Some games like Pokemon Trading Card and Link's Awakening DX have this function. Thank you.

Hello, i'm seeing that @TheDimensioner already found the way to use this emulator with 240p with some tweaks.

I downloaded the latest version from this site: https://mundowiihack.wordpress.com/2019 ... v20170705/

Then I modified the meta.xml using your pastebin, but I'm still seeing 480i resolution. Any idea what am I doing wrong?

I really appreciate your help

Using two languages for now, cause I don't know which one you speak / Usando dois idiomas por enquanto, pois não sei qual você fala XD!

So, what enables 240p, basically, is the "<arg>--scan-mode=non-interlace</arg>" option. The rest of the options that I had added on that paste.bin post were specific to my TV, because I was seeing some weird artifacts that ended up blurring the image for me. Since it's been so long since I've done modifications to that, I wouldn't know how to explain exactly what each thing does, but the discussions here on this thread and over at "mundowiihack" may explain some things. In any case, I'll attach my latest "meta.xml" for you, so I hope you can get the emulator working in glorious 240p! But keep in mind that your TV type or settings might affect how it displays 240p. I'm using an old CRT, so it has native support, but more modern CRTs might not actually display 240p properly, just like the majority of LCDs, with scaling filters and all that.

Então, a opção que habilita 240p, basicamente, é "<arg>--scan-mode=non-interlace</arg>. O resto das opções que eu tinha adicionado naquele post do paste.bin eram mais específicas para a minha TV, porque eu tava vendo uns negócio lá que deixavam a imagem borrada. Mas já faz tempo que eu mexi com isso, então eu não saberia explicar exatamente o que cada opção faz, mas as conversas aqui nessa thread e lá no "mundowiihack" devem explicar algumas coisas. De qualquer forma, vou colocar aqui o último "meta.xml" que eu fiz aqui para você, então espero que consiga fazer o emulador funcionar no glorioso 240p! Mas um detalhe: o tipo da sua TV ou as configurações podem afetar a maneira que ela exibe 240p. Eu uso uma TV CRT (de tubo) antiga que tem suporte nativo, mas as CRTs mais modernas as vezes não mostram 240p corretamente, igual a maioria das LCDs, que tem aqueles filtros de escala e tal.

Ae YOU seeing 480i, or does YOUR TV assumes the signal is 480i?
My TV just ignores 240p and takes it as 480i, it is very common.
Unless you have a CRT, there's little chance that you can get any benefits playing in 240p.
I personnally use sf modes with GBI, not to see mixed scans on my setup, it may work with mGBA too?

I found what was the problem. I was trying to launch the emulator from the channel (.wad) that I installed from the mundowiihack zipped file that I downloaded.

Launching the emulator from Hombrew Channel works perfectly in my OLD CRT, it works perfectly and looks awesome with the overlay and 240p.

Is it possible to pick a color palette for original Game Boy games?

There is a way, when you append a CLI file to GBI to do so, It may work with emGBA as well.

Tested GBA saves portability: Tested with Doom. It works well, but with the Supercard miniSD, the roms can't sit on the same card, since it can't run unmodded GBA roms, and emGBA has a hard time running supercard modded roms.

Tested GB emulation accuracy: Tested with Road Rash. Best than on Nintendo's hardware, the game is playable on anything else than monochrome gameboys at last! Still have to check video settings possibilities to improve display.
