Looks like some work being done towards supporting headphones?

 

[Hark0n]

As long as it is being worked on, I am happy... this has too much potential to be abandoned.

profi200 is on fire. He has added the HTV04's savegame database.

OAF0 = 240x160 no scaling, no filter.
OAF1 = 240x160 with bilinear scaling to 360x240, no filter.
OAF2 (default) = 360x240, no filter.

Big thanks for uploading this!! Highly appreciate your efforts.

You uploaded two 7z files called OAF0, they are both the same build or you named them incorrectly?

 

[Deleted member 323844]

Wops. Wrong name, first file should be OAF2.

Latest commit.

42b4ad4ce1755d2915437158724be51d802df7f1 Begin separating oaf into lib and FIRM. Removed unnecessary config.ini file.

@stranno
Is possible make 240x160 but really in the middle of the screen like GBA VC?

What is the difference between OAF1 and 2?

What is the difference between OAF1 and 2?

I'd like to think i understand the difference... but if someone is kind enough to make screenshots, it would be appreciated and useful

What is the difference between OAF1 and 2?

I'm only interested in native resolution. Haven't tried 1, but I assume one is bilinear, the other is nearest.

OAF1 uses bilinear scaling
OAF2 uses so-called "sharp biased" scaling method. Looks less blurry than bilinear but a bit more pixelated. It's a matter of what you find best.

Thanks. OAF2 looks cleaner to me. Also if anyone cares, the solution to using modified roms that aren't in the savegame database (in my case, using IPS patches) is to set `bool saveOverride` to true in the config.ini file and manually select the correct save type. Both auto save type and the database will usually fail to set the correct savetype for EEPROM_v122 games like Super Mario Advance 3 Yoshi's Island if you modify the rom in any way (likely a CRC check).

Profi200 has released a new official release,

I am having a problem where every game with no savetype is booting to a white screen. When I use the old build from December 2020, the games are working but not with the new build. I tried 3 different SD cards already and no luck. Anyone have an idea?

Could you give some examples? I would like to check that.

I posted on the github about it here as well: https://github.com/profi200/open_agb_firm/issues/48

Seems that profi200 fixed it just now. Now I just need a new build with the fix included.

 

[Deleted member 323844]

Here.

 

[daRealist]

Here.

Thanks so much! Seems the issue is completely fixed now, so happy to be able to have this on my 3DS!
