Hi, 

  I have been toying with some GBA development and experimenting with different emulators. I've managed to get mGBA set up using GDB and Visual Studio to give me some decent line by line debugging of my C code. But I'd really like to know more about this feature that's mentioned on the main page "GBA: Support printing debug strings from inside a game" and if there's any instructions on how to get this functionality working using ASM or C.

Other than this, mGBA is really nice to use for GBA development so thanks, and the inclusion of GDB hooks is brilliant.

So I'm installing the .cia on my emunand (11.7U), run the app, it brings up the menu so I navigate to a rom file (tried many), and when I select it I just get a "Loading" message that seems to freeze. Anyone have any experience with this and know how to fix it?

Hey endrift,
Last time I tried playing some GBA games on the new 3DS on mGBA v0.6.1 and I found the framerate and speeds weren't very good, so I stopped playing. However, after updating to v0.6.3 and setting the framerate from 5 to 0 (which I thought I did on v0.6.1 but maybe I didn't?) the games are running very smoothly! Is this due to the improvements from v0.6.1 to v0.6.3 on the new 3DS or was I missing something 6 months ago? Thanks in advance, I look forward to hearing your insight on this.

mGBA edition:   0.5.2
game:               Pokemon Emerald 386 Chinese Edition by Some Amazing Programmer
problem:           after setting the time in game when I started play, the time on clock never changes, and I was stupid to set it at a time when Shoal Cave tides. As a result, I can't get into most of the cave.

question: how do I make the time move / or just set a different time in my current progress without having to restart the game all the way from the beginning?

Hello endrift,

I thank you for your fix to the RTC implementation by interdpth which is used in prime-dialga's DNS program. That RTC implementation however does break communications for some reason.

Anyways there is another RTC implementation originally by ZodiacDaGreat (posted here: https://www.pokecommunity.com/showpost.p...ostcount=2) that was re-utilized and enhanced by Shiny Quagsire for his Wizard-DN system (here: https://github.com/shinyquagsire23/Wizar...er/rtc.asm). Fortunately, this one doesn't break communications, but it doesn't work in mGBA. This is the patch it is a part of: https://www.pokecommunity.com/showthread.php?t=409672 which was originally obtained from here: https://www.pokecommunity.com/showpost.p...ostcount=1 

I'm not entirely sure if this is the same problem that you posted here: https://twitter.com/endrift/status/959123576430317568, but I did try looking for similarities between both implementations to see if it had the same bugs. My limited ASM hacking knowledge hasn't really been able to see if it's indeed the same problem as the other implementation so I turn to you for help in fixing this if possible.

Thanks for your time and I hope you'll be able to help.

hello.

first at all, I have to say thank you for your work.
and my own language is not english.
please understand even I can't translate my language.
if you feel I'm rude, it's not my intent.


I have n3ds. and I really want to play gba on my machine.
but retroarch gpSP core have random crash because bad compiled dynamic recompiler that I known.
and mGBA that your work is safe but frame is low because don't have dynamic recompiler. just I known.
VC injection is uncomfortable and not supported my own contry.

do you have any plan for dynamic recompiler?

thank you.

Hi everyone,

I found mGBA today, and tried it out. It has better performance than my previous emulator, and finally there are no sound glitches. The only thing that's off-putting for me is that the save state files use a file extension called .ss1, which in itself is not a problem whatsoever, but I also use GBA4iOS on my phone, and it's pretty convenient that I can move save files between devices and pick up the game from where I was.

However, GBA4iOS only works with .sgm file extensions. Is it possible to make mGBA use .sgm for save states instead?

I really don't know how the process works on this emulator.

Hello! I'm using lastest 5138 revision on win64 platform. The emulation rewinding feature seems not working properly to me. When I hold backquote, the game rewinds with lots of graphic or/and audio glitches. Sometimes an error message pops out and mGBA turns back to show game library, which message says The game has crashed with the following error:Jumped to invalid address: 0B058054. I wander that it's happening to everyone or just me.

Hey. 
I've been playing Pokémon Red on this emulator recently and it was all going well until I realised that the color that you would see in the GBC when you played this game, it doesn't exist. In the emulator, it's all black and white with a little bit of green, but I remember playing it on the GBC with the red background and pokemon sprites. I don't know if there is a way to fix this, if not then I'm fine playing like this, but if anyone knows what to do, please tell.

Thanks for your time.
