Hi All,

Love mGBA, but I hate how 640x480 retro handhelds make GBA games look. It's either uneven or blurry, or both.

With millions of people playing GBA games on such devices and screens, I think we could do a better job.

I used to be an embedded game dev for over a decade, so I came up with a simple but elegant scaling algorithm, that is consistent and retains the sharpness without uneven text.

I'd love to integrate it to mGBA, if possible. It'd be a very specific scaler for the 240x160 to 600x400 scaling only, although I could generalize it to be useful for 2.5x, 3.5x, 4.5x scaling the same way.
Would this be okay to implement here? If so, where in the architecture would it fit best @endrift?

Here's a simple .js implementation and some samples:

Cheers,

Hi there! I'm Kastel and I am very new to the emulation scene so sorry if this question is really easy to answer but I'm not really seeing how to set up the Library. Other emulators will have a place where its easy to see all the games you have downloaded right after downloading the Emulator but seems like not this one. So if someone could please link me a guide on how to set up said library or just tell me how to in the comments that would be great!

I am trying to trade pokemon from Red to Blue. I open mGBA and then open New Multiplayer Window. I start both games and when I go to the pokecenter to transfer, I can get 1 to "Apply" and the other just tells me "Its Reserved for 2 friends".

How can I fix this?

Hey everyone,

I’ve been going through some classic GBA games recently and was wondering what are your all time favorite GBA titles?

There are so many great games out there, from RPGs to platformers and even puzzle games. I’d love to hear your recommendations, especially if there are any hidden gems I might have missed.

So I started Pokemon Fire Red on John GBAC and I played it all the way to the elite four. Now I want to play it on the Wii and I tried changing the .sav file with mine, but it didn't work; then I noticed that when you save progress in a save slot it gives you a .ss1 file, meanwhile I have 2 files for the same slot, one is .jg0 and the other is .js0

Anyone knows how do I transfer it?

i just downloaded mGBA, this is the first pc emulator i've ever used, so im sorry if this question has an easy answer and i just don't realize.

i downloaded a sapphire randomizer and can't get my keyboard to work with it, do i need to use a controller to play the emulator and that's why it's not working? or am i missing something else. also not sure how to input cheat codes ^^'

I'm kind of embarassed to be asking this here and it's probably a dumb question, but I can't get my screen back to normal. I was playing radical red, missclicked on something on my keyboard and it made the emulator become a permanent fullscreen, just like in pic related.

I didn't click on anything in the configurations, it really was something I pressed on my keyboard while playing the game and now the screen just doesn't change back to normal anymore. When I load a rom, the emulator hides the top white part of the screen on the print with the options and you can't even access them anymore.

I already deleted and dowloaded it again but nothing changes, Anyone can help me out?

Im very new to the emulating scene and wanted to know where i could find these ".sav" files which contain save data for my games?

Ive been playing Wario Land 4 (Because of Pizza Tower) and each time i boot up the ROM through my downloads, all the saves appear empty. So i have to rush through the levels to get where i was at before, Maybe i could be a WL4 speedrunner, heheh. Jokes aside, the game sure is fun to replay but i want to continue progressing through the game.

If someone could help me with this, it would be much appreciated.

It really does. Up to three trigger presses to select an action, and if you do one more it's four more.

I had an idea for a better scheme: triggers work when held, not pressed. Press the back bro's button while holding R to bros. jump, press either bro's button while holding L to hammer with that bro, and press either bro's button while holding L and R to hand with that bro. While I'm at it, A always controls Mario and B always Luigi regardless of who's in front, just like in battle.

My ideal romhack would be this control scheme in the Japanese version with European language options. I'd even take a crack at it had I the executive capacity; the GBA is a fascinating little machine.

Question I keep getting rng clones here and there when doing 8x instances for soft resets for charmander in fire red and leaf green how do I stop that completely in mgba?
