  Save/load States not working on Super Mario Land 2 DX
Posted by: ShadowOne333 - Yesterday, 05:21 PM - Forum: General - Replies (1)

Hi endrift!

Lately I've been playing a lot of toruzz's new colourization hack for Super Mario Land 2 found here:

However, I've been experiencing some weird issues when using Savestates and loadstates on multiple builds of mGBA.
I tried RetroArch's, 3DS and Windows build of mGBA (latest nightly) and they all seem to do the same.

You can reproduce the issue by simply starting up a new game, making a savestate in the first level, and then reset the game and try to load the state from ANYWHERE else in the game except the same level (this can be easily tested if you made the save at the fisrt level, and try to load the state from the World map)
The result ends up being Mario/Luigi dying instantly upon loading a state, and the background/level layout being a complete mess.

Other GB/GBC games seem to work fine with states, it's just this hack so far that I am experiencing issues with saving and loading states with.

If you need any more info to debug this, please let me know!

  multiplayer supports pokemon trading in RBY and Ruby/Sapphire, but not GSC
Posted by: sabinscabin - 05-17-2018, 05:50 AM - Forum: General - No Replies

I'm using mgba 0.6.3 on macOS high sierra, and pokemon trading works perfectly between yellow and blue, as well as ruby and sapphire. I simply open a new multiplayer window, and the link cable works automatically, and I'm able to trade pokemon without any issues.

However, when I try to do the same for gold/silver/crystal, it doesn't work; the game simply says "your friend is not ready", which I'm assuming indicates that the game thinks the link cable is not connected.

Is this a known bug? It's strange that link cable would work for gen 1 and gen 3 pokemon, but not gen 2.

  mGBA shortcuts on 3ds

I am trying to find all the shortcuts for this emulator on the 3DS, like going stretch to fullscreen, going back to menu etc. Does anyone know where to find them?

  mGBA can't detect my save files
Posted by: Hendrik498 - 05-13-2018, 08:26 PM - Forum: General - No Replies

I was playing GTA Advance, whatever happened and the game suddenly froze. No problem, I simply resetted the game to load my last save, but none of the saves were there, despite the .sav file still existing.

How can I fix this problem?

  mGBA libretro core accuracy on other emulators than Bizhawk
Posted by: Gnuk - 04-30-2018, 05:59 AM - Forum: General - Replies (1)


I discover some games in speedrun.com have those rules : 

-Bizhawk with mGBA core is the preferred emulator, regular mGBA is also allowed but less recommended.

-Any other emulator will not be accepted for the leaderboards

So I tell the players on discord to understand why libretro mGBA core is not allowed for other emulators (like retroarch for example) and they answer me :

It's due to inaccuracy. Bizhawk with the mGBA core was found to be most accurate. We had other emus saving 30+ seconds due to running improperly which is a huge margin in a 15 min run

So i don't understand why any other emulators using mGBA libretro core could have a different accuracy :

Can you help me to understand if another emulator like retroarch using mGBA libretro is really less accurate and why ?

I'm sorry bothering you, but I don't know how to change filters. I'm already with the latest version: 0.6.3, but I don't see any button or option called Filter or anything. Can you please teach me how to change?

Bug Solar sensor settings not detected by game
Posted by: Solarkid - 04-24-2018, 05:21 PM - Forum: General - Replies (5)

I've tried every Boktai rom I have, all clean dums of the UE version and all of them react the same way. I've set the solar sensor up with shortcuts to raise and lower the sunlight setting, but unless I'm missing some kind of override somewhere nothing works. The gamepak override options are checked. I've also tried unchecked, not that that changes anything.
The games continue to react as though the solar sensor is broken and don't react to any setting. Is there a specific patch I missed or some tweak somewhere? I've searched here and the github and only found one mention of the solar sensor and they seemed to be having no trouble.
I know these games and feature are super niche, so I'm not expecting top priority, but if anyone could let me know if they've found a fix, I'm game to try.

Question Overclocking Option?
Posted by: Hot Violet - 04-17-2018, 12:08 PM - Forum: General - Replies (2)

Hey. Firstly, please forgive me if this suggestion induces eye rolling or annoyance. I'm completely ignorant as to how these things work but I thought I may as well ask.

Would it be possible to add an overclock option to mGBA? If so, would it help games such as R-Type and Super G'n'G that suffer terrible slow down?

  Issues with 0.6.3
Posted by: ShadowOne333 - 04-16-2018, 06:17 PM - Forum: General - Replies (5)

Hi there.

I am posting this in behalf of other people in GBATemp.

Apparently, the 0.6.3 regression caused some issues with some games:

Quote:Pokemon Red/Blue overworld sprites are messed up and menu open/close produces odd effects. All of it still absent on the nightly. Also on GBA Pokemon FireRed runs noticeably slower than LeafGreen. A problem again absent in the latest nightly.

Quote:Stable 0.6.3 has slight audio crackling in Golden Sun.

Quote:Now all that's left is fixing save states. (Try SML2 to see what I mean. Survival Kids is also affected in that big rocks can't be moved by a big stick anymore.)

All of these seem to be reports from the 3DS version of mGBA.
The crackling issue in Golden Sun might be because the user is running mGBA on a 3DS, which doesn't have consistent frame rate with GS or GS2. So that one could be ruled out.

As for the other two, I am not sure, I haven't tested them yet, but the user who reported the Golden Sun crackling issue also confirmed the Red/Blue overworld sprites problem as well.
