I take it this is the place to suggest or to explain yout thoughts 1. I usually TAS with Nintendo DS, which makes me use the Touchscreen and microphone. Let's say I want to write an 8 frame long sequence. Let's say I have written a sequence of inputs on the "Touch X" Column that says: 99 99 50 50 20 20 1 1. Then I select the sequence with shift, and I clone the sequence of inputs 99 times. Now, I may realize it is more optimal to write 99 99 45 45 20 20 1 1, instead of 99 99 50 50 20 20 1 1. It would be very useful if I could Select the sequence with Shift and modify the frames which contain the number 50 exclusively. Instead of deleting it whole and write the new sequence, then clone it 99 times. I find myself trying to guess if the best value is 50, 44, 51, 45 or 48 many times. And so I have to keep cloning 99 times, then deleting it all again. Sometimes I have to clone the sequence 99 times, and TAS a bit after the cloned sequences, otherwise I cannot verify if I got the result I was looking for. Then I have to delete it all again. They say madness is defined as "doing the same thing over and over", and at some point you are just tired of cloning the same sequence 99 times, leave it play, then delete it all again. Now imagine I need to do that for every number. First for the number 50, then for the number 99, then for the number 20, then for the number 1. And then I have to see how does it (the modified value of the sequence) affect the other values. Maybe 45 is better than 50, maybe 95 is better than 99, but maybe combining 95 with 45 does not work well. Maybe 97 works great with 45. It's a tedious process. I was hoping that an editor of values can be added to Bizhawk, since I have not found any. I wish that I can select my 99 clones of the sequence with shift, then edit every number 50 within it and replace it with the number 45. A "Sequence Editor". I envy word office, because their users can "Search: hellow -> Replace all with: hello", which is very helpful. I understand I'm using a movie editor, which is different than a word, but I also think a tool like that is convenient for Bizhawk TAS Studio. An experience enhancer. FOR THE RECORD: I am TASing short minigames, like a Hammer Throw spin on a touchscreen. Then I clone the spin (99 times). I see this trend on many minigames. 2. Many times, I have found myself cloning a sequence of inputs 99 times, only to have to Control Z 99 times to undo the cloning. Once per cloned sequence. It's a minor inconvenience, I can always select the 99 clones with shift and delete everything. But I'd like to have a Control Z X times option if I right click. Or to just undo the action of cloning 99 times all together. FINAL: I understand these situations might be anecdotal, but I hope they are taken into account for the next update of Bizhawk emulator.

The option to edit multiple cells (with a Ctrl+click selection) may already exist, I'm not sure. You can definitely "Clone # Times" already, but I think in 2.10 that creates N undo steps. In the next release it will be just 1.

Hey look buddy, I'm an engineer. That means I solve problems. Not problems like "What is software," because that would fall within the purview of your conundrums of philosophy. I solve practical problems. For instance, how am I gonna stop some high-wattage thread-ripping monster of a CPU dead in its tracks? The answer: use code. And if that don't work? Use more code.

While we do already have the ability to load a branch and edit the current branch's text label via lua, it would be nice to have the ability to add/save/remove branches in TAStudio using lua functions.. While the savestate.saveslot() function does work for adding/saving the first 10 branches, it is limited to the 10 savestates. Would it be possible to add some lua functions something along the lines of the following so that a greater number of branches can be created/manipulated via lua?
  • add an indexed branch (optionally with the provided name)
    tastudio.addbranch(int index, , [string message = nil])
  • to save the current branch
    tastudio.savebranch()
  • to remove a specific indexed branch
    tastudio.removebranch(int index)

Lua functions that reference branches should be using their ID instead of index. And there's currently no support for re-arranging branches even with the UI, so I don't think giving an index to the "add" function makes any sense. TAStudio does not know which branch is "current", any further than knowing the current set of inputs. So a "save" function must include an ID parameter. And it should be called "update", to match the UI. So this gives us
  • add a new branch (optionally with the provided text)
    tastudio.add_branch([string text = nil])
  • update a branch
    tastudio.update_branch(string branch_id)
  • remove a branch
    tastudio.remove_branch(string branch_id

BizHawk 2.11 has been released! New cores Lots of updates and fixes to other cores and EmuHawk. Full changelog: http://tasvideos.org/BizHawk/ReleaseHistory.html#Bizhawk211 Binaries: https://github.com/TASEmulators/BizHawk/releases/tag/2.11
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

NESHawk has suffered some regressions in t his release. Ex. [4611] NES Tiny Toon Adventures by Kaylee & Alyosha in 10:59.847 now desyncs. "Count errors" controller reading test ROM's are now broken,. These were previously console verified.

Not sure which test ROM that is in particular. I did some checking though. Going by 100thCoin's AccuracyCoin test suite, which has a couple controller tests that are console verified, the Controller Clocking test regressed somewhere inside this PR's changes. After the PR was merged, the test, which previously passed, then began to fail here:
Docs wrote:
5: (NES / AV Famicom only) The "put"/"halt" cycles of the DMC DMA should be able to clock the controller if the DMA occurs during a read from $4016. The LDA instruction should clock the controller again after the DMC DMA's "get" cycle.
Assuming the "count errors" test is checking something similar, that PR is likely the culprit of the regression. However, in addition to several CPU instructions, that PR also fixed a different controller problem in the Controller Strobing test:
Docs wrote:
4: Controllers should not be strobed when the CPU transitions from a "put" cycle to a "get" cycle.

I got in contact with 100thCoin. He's fixed the above regression, and fixed a related DMC DMA bug too. PR is up! Edit: And merged! As noted in the PR, with these changes, the aforementioned Tiny Toons TAS syncs again.

Hello everyone, I would like some help solving a problem. I recently downloaded the latest version of Bizhawk and opened several MS-DOS games. They all opened and are playable, however I'm having some audio problems. When testing the game X-Men Children of the Atom, it's only possible to hear the sound effects; the background music doesn't play. When testing Mortal Kombat II, the music plays, but I can't hear any sound effects. I've already tried some Sound Blaster options, but it didn't solve the problem, and it's not possible to use Gravis Ultrasound. Does anyone know of a solution to this problem? Thank you in advance.

I'm using the latest dev version of BizHawk for optimal Linux compatibility (as linked here: https://nightly.link/TASEmulators/BizHawk/workflows/ci/master/BizHawk-dev-linux.zip) and I notice it isn't compatible with RetroAchievements. When signing in, the emulator immediately crashes, and it is never able to start up with it enabled.

The issue is unrelated to Linux, dev builds are broken with RetroAchievements due to an unrelated change breaking them: https://github.com/TASEmulators/BizHawk/issues/4603 EDIT: I committed a fix, so the next dev build should be not broken.

While TASing in Bizhawk 2.11's DosBox-X core in TAStudio, I tried copying and paste-inserting several lines of input to the end of the movie, then Undo. This causes an unhandled exception, but Bizhawk will continue working after this. Something about System.OverflowException, and array dimensions being exceeded. EDIT 1: In Bizhawk 2.11, also while TASing in DOSBox-X, I tried copying input in TAStudio from a movie that had mouse input to a movie that had mouse disabled, but it just made all keys active. EDIT 2: In Bizhawk DOSBox-X, while TASing in TAStudio, if I press Left mouse button at the end of my run and save that to bk2 and play back the movie, it doesn't register the left mouse button press, even if I put 1 additional idle frame before exporting to bk2. EDIT 3: When TASing DOS, please make it possible to clear mouse coordinate/speed input in TAStudio. It seems once there are values, they can't be removed... EDIT 4: Opened issue for the problem mentioned in EDIT 3.

I have seen an odd behavior two times in the past 2-3 weeks. The window for Bizhawk 2.11 would suddenly go to position (-32000, -32000). This time it happened when I selected a recent ROM (.hdd) to load, then set another window on focus to do something else, then looked at Bizhawk and couldn't find the window... The config file would say "MainWindowPosition": "-32000, -32000", and I have to set it to (0, 0) to fix it.

Hey, I'm sorry if this is the wrong place to bring this up, but the emulator forum seemed like the most relevant place to ask about this. I've been using Bizhawk as a casual player for a while now and I love a lot of things about it, but there are some things I was wanting to ask about it in relation to functionality and features. If this is the wrong place to ask, I will gladly move this elsewhere. First I wanted to ask if there was a way to maintain static window sizes across all emulators to prevent constant window size changes, I've been wanting to find a way to force all games to conform to a 4:3 aspect ratio in a window that is roughly 1280x960 in size (not necessarily that exact set of measurements, but a decent size). Something I would like to supplement this with is either a filter to aid in preventing uneven pixel rows in the video without being too visually intrusive, or a perfect pixel scaling feature. As for the functionality of the emulator itself, I often find that the N64 games either break very easily and require a lot a tweaking to get working properly, or require a build specifically curated for one game (like DK64) or using older builds just to run particular games. (Pokemon Stadium and Pokemon Stadium 2 come to mind.) Has there been any interest in getting these games to work all in the next build? I have been using Gopher64 for N64 emulation and it seems to run very well with no tweaking, though I am unsure of emulation accuracy. I would like to try using Bizhawk again for a shuffler of N64 games. More on functionality, has there been any developments for MAME/FBAlpha/Arcade games being more streamlined to use? As it is now, getting games on the NeoGeo or CPS2 games that use QSound to work requiring the disc bundling feature is quite cumbersome. Could they have their resources be loaded into a Bios or Firmware folder and be loaded automatically whenever the correct game is selected? I've been unable to get a lot of Konami arcade games to work as well, Mystic Warriors comes to mind immediately. I've seen discussions about PPSSPP, Dolphin, and PCSX2 support floating around the forums, so I won't ask about those, but they'd be very cool to have too. This last question is very much just 'a hopeful bonus,' but is there any plans to implement netplay features to Bizhawk? I assume this is absolutely out of the current scope of the emulator as I am sure it is meant to be an emulator with the goal of achieving greater accuracy for speedrunning and TASing. This is largely a question of curiosity is all. While rollback capabilities would be fantastic, I am perfectly satisfied using Parsec and the such to play multiplayer online. I hope this doesn't read as a list of demands, I really don't want to pressure or pester anyone about this, given I am but a layman, but I just wanted to get my thoughts out there. Thank you for taking the time to give this post a read, and hopefully I can read your answers soon. Oh, and thank you guys for making Bizhawk in general, it's my favorite emulator for mostly everything PS1/Saturn and older. It's a much more appealing and user friendly option than Retroarch, as far as I am concerned. Keep up the good work!
You have 3 guesses, and the 1st 2 don't count...

An update to Mupen is in progress, but beyond that we're all just waiting for ares to improve, since there are no other competitors.

I don't think so. We're not trying to replicate or replace MAME's own frontend for casual play.

PPSSPP is done modulo bugs. Grab a dev build. Dolphin was added in a fork, but development stopped ages ago. No-one ported PCSX2 since it was unstable for the longest time.

Bizhawk not recognizing files through .XML I might have come across a problem where Bizhawk is supposed to mount a floppy disk file to A:, but doesn't. I'm trying to load a few .img floppy disk files along with a pair of .cue / .img files as an .xml. Bizhawk does provide "previous/next/swap floppy disk" inputs, but only the .cue/.img is mounted to D: The floppy disk files are recognized and can be changed/swapped, but drive A: is not set up and files are not mounted to it. This happens regardless if I list them before or after the .cue/.img pair in the .xml. This means I will have to work with two verification movie files. Bizhawk creates branches while I'm entering a number In TAStudio when I enter a mouse coordinate/speed, Bizhawk sometimes interprets it as "save branch" even though TAStudio is in focus. Make it possible to load Sync settings Make it possible to load sync settings from a movie file or a savestate, to avoid problems like this.
