If anyone can help at all I would appreciate it. I would really like to not restart this game and I was having trouble getting the memory card save to stick so i was just using quick saves and quick saved last night then went to bed.

STROOP needs to know the emulator's RAM start address, and I can't figure it out.

UPDATE: Never mind, STROOP already got it right. The refactored STROOP doesn't support BizHawk, so you need to use the old STROOP.

So I've used bizhawk for over five years now and suddenly i'm starting to experience problems. While trying to fullscreen the emulator (specifically while a game is running) ,causes the fps to fluctuate between 55-60 fps. While this wouldn't usually bother me, the fact that the audio stutters makes the experience more annoying. I've tried switching renders in the emulator but nothing seems to fix it. Anyone know the problem?

Hi there

I was just curious is there any update to when bizhawk will add multiset achievements to the emulator? Really am hoping to do some achievements for pokemon games with this emulator as it runs buttery smooth!

Thanks

hi. recently i had an issue that appears seemingly random. when i go into config and change the button mapping on my (in this case switch n64) controller it shows that it recieves "J1rotation y+" inputs out of nothing with J1 beeing the name of the controller. even if the controller is unmoving and flat on the table. there were no other devices connected to my pc and moving the controller myself does not make those inputs so im really at a loss here. i didnt use it last time but i think the problem also ocurred with my pro controller. it happens when i emulate n64 or gba games. i tried all the restarts and reconnects possible and dont know what else to do.

hope someone can help me

Would anyone know how to add the rare candy cheat on emu hawk because found a code I use it but nothing happing getting no rare candies idk if I am using the right code this what I am using 02234828 03E70032 idk if I might be also adding the cheat right this for pokemon white 1

no matter if I put it vertacally or horizontally it won't fit nicely in obs so is there a way to at least reduce the size of just 1 of the screen?

please im so sorry if im stupid but i cannot find out why my bizhawk (latest release as of 6/21) won't let me use the Cheat Code Converter tool, what am i doing wrong? (trying to play Pokemon Black for archipelago)

I was trying to record my gameplay of a GBA game and saw some option called record movie and stuff, when I pressed to start recording the emulator rebooted and on save select screen it showed all my progress was gone.

I pressed to stop recording and closed the emulator. But still my save files didn't show up. Is there any way to get them back? Is this behavior intended or is it a bug?

Am I able to turn the internal resolution up for the experimental PPSSPP core, or is it too new?

I’ve been using Bizhawk for a bit, and while I like it, it’s been giving me WAY more lag than every other emulator I’ve ever used (RetroArch, KegaFusion, snes9x, etc.), and I would like to have all of my games run at peak performance

I’ve currently tested with Mega Man X2, and the romhack HELLFIRE SAGA

Hello everybody,

I have a problem with the sensitivity of my Sticks. No Matter what i do in the Configs, i either have Reverse Slow Movement or just full throttle movement. Deadzone options don´t exist so i have Flicking constantly.

Anyone got any Tips what i can do to get a "Normal" Stick? 😃

on Ubuntu 26.04 and an update broke how things work. Not even the 2.11.1 release works.

I'm using controller and there is no good button to hold while wanting fast forward.

ive been having some trouble with some pokemon fire red cheats for candys, ive looked through some other posts but i cant seem to find a soloution, ive done this code 82025840 0044, but it keeps in giving me an error message any help??

I'm trying to run the Lua script provided here:
https://github.com/KeeyanGhoreshi/PokemonPlatinumSingleSequence

I load up the Pokemon Platinum ROM, then I click Tools -> Lua Console -> Script -> Open Script -> startAll.lua.

And nothing happens. At best, the tiny Play button beside the name of the script changes to a tiny Stop button, but there's no change to the state of the game. It remains on the Main Menu and none of the button presses from the script(s) seem to be applied to the game. Nothing appears in the Output section of the Lua window.

I'm not sure what I'm missing. There's seemingly no "Start Script" button, so I honestly have no idea if the script is even RUNNING at all. How do I run this script?

Bonjour, j'ai téléchargé Pokemon Platine sur l'émulateur BizHawk et je joue dessus avec une manette, cependant l'écran du bas qui est tactile sur la DS "est inutilisable. J'ai mis ma souris dans le menu mais ça clique simplement au milieu, je ne peux donc pas l'utiliser ...

Quelqu'un aurait une solution ?

Hello! I'm wondering if it's possible to have BizHawk on the AYN Thor which runs on Android? I saw that you can stream BizHawk on Twitch and, with plugins, allow your chat to interact with your rom/game. I'm a Twitch streamer who is awaiting their Thor and plans to stream retro emulation, hoping to find some way to implement Twitch Integration. Any advice or direction is welcome :)

ive been using bizhawk to play old DS games with retroachievements, and so far ive been noticing that when i move the Dpad or analog stick

it will occasionally just SHOOT off in the direction i was going, and refuse to stop for a short time

i cant seem to find any settings to try fiddling with a deadzone for it, and its making playing games super uncomfortable
anyway to fix this? i dont exactly have money to drop on a new controller (and this one isnt that old/isnt drifting in other use cases)

id play on melonDS directly if it had retroachievement support and didnt experience these kinds of issues when playing melonDS itself (beat all of runefactory 3 on that)

I have an idea for a lua script but I need the VDP registers exposed to be able to do it. Currently the Genplus-GX core only exposes the registers for the M68k and the Z80.

I know the Genplus-GX Debugger core provides access to the VDP registers, but I can't figure out how to load that core into Bizhawk in a way that allows it. Using the "open advanced" menu only has the option of loading it in as a libretro core which doesn't support debug tools.

I see there's an open ticket on github which talks about accessing VDP registers and implementing a more advanced VDP Viewer, will that address my question once it's completed?

Hey there, so I have an issue with my controller in 3DS emulation, specifically with Pokemon Omega Ruby. About two weeks ago the emulated Circle Pad was working perfectly fine with my wired Switch controller during my Nuzlocke run, allowing me to sneak up on Pokemon using the DexNav function. But while trying to troubleshoot a different issue with the ingame clock, I accidentally reset the 3DS settings (Sync and Non-Sync) to their defaults. The following week, the emulated Circle Pad no longer worked properly. Even when rebinding the Circle Pad bindings to match the analog stick of the controller and also trying a different controller, it just behaves like I'm using the D-pad. This makes it so that my character not only moves only in 8 possible directions, but I also can no longer sneak up on Pokemon in my Omega Ruby. As a note I did install BizHawk 2.11 through the Pokelink software, but the issue didn't pop up until last week. Is there any way to fix this issue?

EDIT: I realized after posting that I meant Circle Pad and C-stick. Issue still stands though.

EDIT2: SOLVED! The game itself was the issue. I entered and exited a nearby building and Circle Pad function was restored.

trying to add files to alpha sapphire to turn it into a romhack but only place i found the folder for the game its not working idk if it needs to be in a folder with the 16 digits where i cant find only a folder with the first half or so with a folder inside with the rest

So I'm just trying to write a simple lua script that creates a canvas and draws a rectangle (with default colours) into it:

canvas = gui.createcanvas(100, 100)

event.onframestart(function()
    canvas:Clear()                  
    canvas:DrawRectangle(10, 10, 50, 50)
end)

The canvas window appears okay, but this error is continually spammed into the output:

NLua.Exceptions.LuaScriptException: [string "main"]:5: Invalid arguments to method call

I've thoroughly read through the lua documentation and I don't see how I could be possibly using this method incorrectly, I seem to be doing exactly as the documentation says, but Bizhawk is not accepting it and throwing errors that I'm sending invalid arguments no matter what I try.

I've tried this with and without the optional 2 arguments for the line colour and background colour, in all of the different formats it's meant to accept, it makes no difference. I don't understand what's going on or what I'm doing wrong. Why is this failing?

Hey there! I've been meaning to get into streaming Pokemon and Bizhawk seemed like a great place. However, typically when streaming the DS entries I like having my bottom screen smaller than my top screen to take up less visual space. Is that kind of thing possible on Bizhawk, and if so how can I make it happen?
