Smea seems to think it's pretty doable at least for the twl_firm, not sure why it wouldn't also be possible for agb_firm.so you can totally change the way it does that, apply some post processing to that if you're into that, but that's basically it. I have some documentation on lgyfb, but the gist of it is there's some configuration for the upscale filter
100% possible, not even very hard. not sure (dont remember) if LGYFB's builtin filtering method would allow that directly (i suspect it would), but even if not you could just grab the original framebuffer and upscale it with the GPU. (twl_bg already uses the 3DS's GPU to render to DS mode framebuffer, so at that point it's just a matter of changing texture settings to nearest pixel and scale factor)
Yeah, someone do that by the time I bother to dump my GBA games. [That GBA boot screen is SO COOL, thanks @Aurora Wright !!!!]We don't need to add any filters, we need to remove the awful darkening filter they have and the piss poor motion blur one too. And remap buttons while we're at it.
I wish I could do all of this.
Just use retroarch.I know that AGB_FIRM is the thing on 3DS that runs GBA titles in it.
Would it be possible to... patch the AGB_FIRM to add graphic filters, or even shaders?
Why haven't you written some sick filter mods for AGB_FIRM yet? Obviously you think just anyone can write this stuff, so get on it. We're waiting on you hereI'm aware but then why wouldn't be able to do way more than just signature patching or whatever it is luma does.
I didn't mean it In that way at all. That's why I said is someone is willing and that no one who knows what to do is interested enough I was just talking about if it's a possibility..Why haven't you written some sick filter mods for AGB_FIRM yet?
