Hacking mGBA Discussion Thread

Megaman Zero games have seen a super steep increase in performance with the most recent nightly build, staying pretty at or above 55fps. It seems the performance improvements are coming, also welcome is the option to remap controls, but can we also get remapping of emulator functions as well? I've always played GBA games on my PS3/PS4 controller with B mapped to square, but I cannot unbind menu change off square, so now I trigger a screen mode change every time I have Zero attack. That, too would be a welcome addition.

Good luck finding a native Vita version of that.

Besides, mGBA is way more accurate than gpSP and is actually still updated.

im on the latest version lol and it runs all games at 60fps

plus i have vhbl

We all have VHBL. But development really should be transitioning over to native Vita applications rather than being held back by dated PSP homebrew.

Not to mention it is a native Vita app so we don't have to use VHBL(ugh ePSP stuff). We should be leaving that headache behind.

i agree

Castlevania AoS works very well (full performance most of the time ingame), but very often crashes on the save loading screen. Also doesn't seem to hold saves, but save states are usable.

Homebrew is still relatively new on VITA. The 'problem' with mGBA is that it doesn't use dynarec (see their forums) while gpSP does. That is why -at the time- when Exophase released gpSP it blew everything else out of the water on the PSP. A port of gpSP runs on the DSTWO flashcard. So perhaps on desktop computers the static interpreter is fine, on lower-powered systems the dynarec engine might help get the last bit of performance to get it to "real hardware" level?

Final Fantasy Tactics completely glitches out during the snowfight at the beginning every time
Tactics Ogre shows white screen
Mario Tennis and Golf glitch up

all 3 of these are unplayable.

Mario advance 3 plays perfectly but has no music and sound glitches.

Castlevania HoD freezes once you press start

I seem to have run into a strange bug... Trying to run "Pokemon pinball ruby and sapphire" but the ball doesn't make it out of the launcher?

I tried three different rips all with the same issue but they all worked fine in VBA on Windows. Could this be an anti-piracy thing that mGBA can't handle or isn't handling properly?

 

[ma16v3]

So now it seems games are running over 60fps and we don't have a framelimiter or Vsync to address this. Any chance this will get implemented soon?(Megaman Zero 1-4 were tested).

We also still need the ability to remap menu functions(ie screen mode, settings menu, etc).
