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

NES TAS of 2011
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 10:59.85 now desyncs. "Count errors" controller reading test ROM's are now broken,. These were previously console verified.
Accepting hardware donations for console verification! See my homepage for details: https://tasvideos.org/HomePages/Alyosha Monetary donations also accepted via gofundme: https://gofund.me/82aabaee

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.
