Hello everyone.
I don't know if it's the right place to talk about this but...
I've stared to make small patch that allows BizHawk to load kind of "External tool".
In summary, I just created a brand new project on vs2015, add BizHawk.exe in project references, add a simple windows form make it implements a specfic interface and build the project.
Then, I put the dll in a specific folder, run a compiled Bizhawk, open a ROM and it loads my custom winform.
I thought about doing this while I wanted to create a window with lua scripting. We can do it but it's quite complicated (and there are some limitations). So if we could run compiled code, we should probably make more crazy stuff.
What do you think about this? Could it be interesting? If so, how can I submit the patch to the project?
PS: The patch has been really easy to make, it is a proof that the code is well thought (at the least for parts I see :p). Great job guys !
We're going to have something like this eventually. I think we're more interested in the crazy thing youre doing and what kind of snags you run into than your exact implementation so far, so please report your findings, in a separate thread if you wish.
Question regarding this Dual Gameboy and Dual Gambatte that I'm reading about in the about window and paths window.
Is there a way within BizHawk to link between Gameboy/GBC games at present, or is that framework just there for future use?

It does work, as far as I am aware. I tested it against Pokemon Red and Pokemon Blue back when. There's even a command to disconnect the link, for whatever reason you want to.
When TAS does Quake 1, SDA will declare war.

Oh good, it's not just prelaid infrastructure.
Now to figure out how to make it work. Is it documented somewhere? The wiki is decidedly unhelpful in this respect.
I have run into some kind of problem/bug with lua, I think...
I have a script that saves stats and properties of Mario and Luigi into the objects Mario and Luigi (it does this on start-up and every frame inside a while true do loop). And I have objects MarioBefore and LuigiBefore that save the values from the frame before.
local Mario = {
Health = memory.read_s16_le(0x4866),
HealthMax = memory.read_s16_le(0x486A),
BP = memory.read_s16_le(0x486c),
BPMax = memory.read_s16_le(0x4870),
Pow = memory.read_s16_le(0x4874),
Def = memory.read_s16_le(0x487c),
Speed = memory.read_s16_le(0x4878),
Hige = memory.read_s16_le(0x4880),
Level = memory.read_s8(0x4888),
Experience = memory.read_s16_le(0x485c),
X = memory.read_s24_le(0x6c14),
Y = memory.read_s24_le(0x6c18),
Z = memory.read_s24_le(0x6c1B),
Altitude = memory.read_s24_le(0x6c20)
}
local Luigi = {
Health = memory.read_s16_le(0x48a2),
HealthMax = memory.read_s16_le(0x48a6),
BP = memory.read_s16_le(0x48a8),
BPMax = memory.read_s16_le(0x48ac),
Pow = memory.read_s16_le(0x48b0),
Def = memory.read_s16_le(0x48b8),
Speed = memory.read_s16_le(0x48b4),
Hige = memory.read_s16_le(0x48bc),
Level = memory.read_s8(0x48c4),
Experience = memory.read_s16_le(0x4898),
X = memory.read_s24_le(0x6fb0),
Y = memory.read_s24_le(0x6fb4),
Z = memory.read_s24_le(0x6fb8),
Altitude = memory.read_s24_le(0x6fbB)
}
local MarioBefore = Mario
local LuigiBefore = Luigi
...
while true do
local Mario = {
Health = memory.read_s16_le(0x4866),
HealthMax = memory.read_s16_le(0x486A),
BP = memory.read_s16_le(0x486c),

Z = memory.read_s24_le(0x6c1B),
Altitude = memory.read_s24_le(0x6c20)

local Luigi = {

Altitude = memory.read_s24_le(0x6fbB)
}
...
code that compares them
...
local MarioBefore = Mario
local LuigiBefore = Luigi
When I start the script, MarioBefore and LuigiBefore seem to have wrong values though. Log of MarioBefore:
Notice that the very first frame has wrong values, but all subsequent frames are correct.
How come MarioBefore has such wrong values even when I made sure to run MarioBefore=Mario before it even enters while true do territory?
This happens because you need to create another table and copy the values, one by one.
Programming in Lua wrote:
You may think of a table as a dynamically allocated object; your program manipulates only references (or pointers) to them. Lua never does hidden copies or creation of new tables behind the scenes.
Script active problem:
It looks like I found a bug for real this time.
print("Script is loaded")
event.onloadstate(function()
print(emu.framecount())
end)
while true do
emu.frameadvance()
end
I'm on VBA-Next.
When I run this code and load a state, it prints the framecount once, which is expected.
But if I drag and drop the script into the lua console (as a habit to close and reopen the script - this being the only way you can do so in mGBA without crashing the emulator), it looks like subsequent loadstates will execute the print() command multiple times, even though the console says there is still only 1 script active.
///
When the script is active and I drag and drop the file onto the console (which should close the script), the script still keeps going. If I drag and drop it again, it seemingly loads a 2nd instance of the script.
Hex editor problem:
One other error I found was in the hex editor, it seems the wrong character on the right is highlighted when clicking on a byte.
http://i.imgur.com/hGHlej0.png
Also, when I click on a character on the right, the character 3 spaces to the left gets selected instead of the character I clicked on.
Both bugs have been reported as issues.
Btw, I think a event.onloadstateimmediate() could be convenient (run code inside it before emulating the loaded frame). Is this possible? Or what alternative can I use?
According to ASCII tables, 0x26 is '&'.
Which makes sense, since the ROM names are MARIO&LUIGIJA88J and MARIO&LUIGIUA88E, respectively.
Edit: Same as https://github.com/TASVideos/BizHawk/issues/490 . Apparently it has been fixed in builds since Aug 31.

1.11.2 is now Released!
This is a big release for windows users, particularly those with poor openGL support. BizHawk can now be run in directx mode. For those without opengl , this is a huge speedup. (For others directx might perform better than opengl anyway)
In addition, some big features for movie making including TAStudio branches, and SaveRam-anchored movie support.
More details:

Your answer is completely useless to me. How am I, someone who isn't exactly an expert at Lua to begin with, supposed to know how to use that code because for all I know I could be using a wrong script and deem it on that when it doesn't work in any one Bizhawk release. And the release history doesn't list any previous dates so I can't easily find out what is the span of time until a next release can be expected.
I have posted questions here for others to answer them, not so that others can make fun of me when I'm seeking advice.
Just discovered Basic Bot.
Is there some way to get it "playing" indefinitely, similar to RNG Plays Pokemon, without setting it to call an invalid save state? It's doable by setting a non-existing save state, but I don't like clogging my message log with "Savestate not found" warnings.
EDIT and it's not checking the values again every X frames on a failed loadstate, rather once it fails to load state it just checks every frame. Is that an intended failure or an unintended failure?
client.SetGameExtraPadding() seems unusable to me, so I want to explain here why. I think I would have prefered a "client.SetGameExtraMargin()".

I suspect it's because of the questions, one is given in the BizHawk documentation and another doesn't have a sensible answer:
For 1, I answered you on IRC already, but suppose I should have put it here as well: Release History: that function was added in 1.11.2
For 2, no clue.
For 3, Bizhawk doesn't have a release schedule. Take that as you will, but imo "when it's done" here is better than Valve Time(TM). As for when previous revisions were released, you could try checking the history of the Release History to find when version information was added.
Even then, it's probably not that helpful: 1.11.0 was added to that page on the 15th of July; 1.11.1 was added on the 25th of July; then 1.11.2 was a far longer gap than those two.
I have a couple of questions.
2) I have a question about the PSX SaveRAM before I turn it into a bug report.
I haven't really paid much attention to SaveRAM because I always use save states. I can get .mcr save files from other sites, rename it to SaveRAM and bizhaw will recognize it without any issues whatsoever.
However, if I try saving the game like I would on a real PSX, then the save is never created. I've tried starting a game without any SaveRAM present, and making a save, and the emu does not create the file. Not even after closing the emu.
I also tried loading a SaveRAM with a save file already in it (gotten from gamefaqs or something), saving a game, and the same thing happens. As soon as I close the emu, the save is gone.
I don't know if maybe there's an option I haven't turned on or something? And yes, I've checked the SaveRAM directory to see if the file is being created, but nothing appears.
So is this a bug? Shouldn't the emu create the .SaveRAM as soon as you save a game like on a real PSX? Or at least create the file after the emu is closed?
(First option is better though, in case there's a crash.)
--------
SOLVED1) I made this request some time ago:
https://github.com/TASVideos/BizHawk/issues/495
When in windowed mode, it's easy to see when a save state is being used because the status bar on the bottom shows you. But when in full screen mode, there's no way to tell if the save slot you selected is used or not.
So, if possible, I request for the messages to say something like "Slot 1 Selected (Used)" or "Slot 1 Selected (Full)" when picking a save slot.
Zeromus replied with "fixed" and closed the issue. But on the latest Bizhawk released, I don't see it? It could possibly be he didn't add it, or maybe it's something I have to turn on?
Could someone point me in the right direction?

Your #1 works in the latest release for me.
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.
Ah, crap, I see now. I was looking for "save state (Used)" and wasn't looking at "save state (empty)" :P
By the way, I see the framebuffer screenshot option you made is intact in this new release. Zeromus said something about removing it (or maybe he just rewrote it?). Whatever the case is, I'm glad it's there.
