I think this is caused by running some lua scripts while using gdi+ display method, right? Change that option, and if only gdi+ display method is supported on your system, then youre out of luck right now.
Tried OpenGL but had fatal error again. Another config I need to fix for finally Lua works?
Hey I found another way to do the above crash from my post, this time without TAS Studios.
1. Open BizHawk
2. Open a ROM
3. Make a movie
4. Advance one frame
5. Make a savestate
6. Advance another frame
7. Change to read only
8. Load savestate
9. Change to write mode and back to read only
10. Advance a frame

What platform? Is this by chance N64?
The original Gameboy. Using 1.9.4
Hey, I found 2 more ways to produce this bug:
Method 1. Load a movie with 0 frames length
Method 2. Load a savestate of any movie's very end frame and frame advance
Not sure why that makes a difference, but it does. With that said, I think I'll just stick to making a generic lua folder outside of the bizhawk path since I don't like disabling my security software.
I noticed this just today.
The way that BizHawk compresses information related to a movie file when creating BK2 appears to have changed between BizHawk 1.9.1 and BizHawk 1.9.2.
For BK2s created in BizHawk 1.9.1, input is compressed.
For BK2s created in BizHawk 1.9.2+, input is not compressed, as can be seen by opening the BK2 directly in a text editor. Apart from making files larger, it also creates the impression that the BK2 can be edited directly in a text editor without any problem, which is false.
There is no issue with playing back BK2s as far as I know.

There's a bootleg game called Beast Fighter for the Gameboy, but when I try opening the ROM, BizHawk simply closes (mapper issues?). Any way to fix this? I'm using the latest version.

I've made it so that you get a clear error message and the emu doesn't crash now. I have no idea what bootleg mapper is being used, but it's not supported and that's not likely to change.
Random crash happens when we reload a Lua script too many times in the Lua Console. (v1.9.4)
1. Load a rom
2. Create, or load a Lua script in the Lua Console
3. Highlight a script
4. Press "Reload Script" 90 times (It can throw a random error at 64 times, but it will freeze at 90)
Enable/disable a script too many times does the same thing.
It also crash with an empty script like this:
while true do
emu.frameadvance();
end
Example of random errors:
1: BizHawk freeze
2: Any kind of error window
3: The current loaded rom file is now corrupted
4: Output > "Unknown Lua Error"
5: Output > "Table"
6: Output > A random error in the script
7: The script doesn't activate and nothing happens
There is probably a data overflow somewhere in the Lua Console script. When the user ask to load a Lua script, the Lua Console script keeps counting up something and doesn't reset.

Lemme help a little bit, the game runs well on hhugboy, so here's all the ROM info I could find:
ROM Name: SACHEN TAIWAN8221
GBC feature: no
New licensee: 21
SGB feature: no
Cartridge type: 37
ROM size: 4096 KBytes
RAM size: 2 KBytes
Country: 35 (Non-Japan)
Old licensee: 0 (none)
Version: 0
Complement check: 7F (OK)
Checksum: 16BF
Hope it helps...

When I'm editing and reloading a script, sometimes it gives me this ("link to object doesn't point to object instance"):
Script is overall correct, it randomly breaks after a bunch of reloads, saying "Lua Interface Unknown Error" (and things Genisto mentioned). Do I need to launch a debug build and see where it happens?
Latest interim.
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.
I think our lua is horrifically broken and after some stress, the module that translates lua tables to .net objects either breaks (in this case) (possibly related to GC) or leaks memory or both.
I don't think there's any way for someone to fix this without ripping out the lua entirely and binding in a new one. It's almost positively a waste of time to debug this.
Lua runs slowly, so I tried closing lua for sections like loading times, and opening it back up when I need it. After several times, this occurred:
And I had to close and reopen BizHawk to make lua work again.
Save files keep messing me over in Game & Watch Gallery 4 if using savestates during the BIOS:
The image on the left is without using save states during the Bios. If I load the state, it doesn't clear the savefile, as seen on the right.
The problem is that M GBA starts with Bios, even if I selected to skip it. It makes syncing rather annoying.
There is a problem with the Lua script: "joypad.set()"
I'm trying to catch and change the joypad buttons with "event.onframestart()". What I want to do, is to disable with false, the "X" button, because it's not needed in Super Mario World, because the "Y" and the "X" buttons does the same thing. I want to use the "X" for an other thing.
The problem is: when I use "joypad.set()" with "X" = false with the table needed, all the inputs remain the same for 2 frames. (the frame after event.onframestart() and the next frame after the next controller inputs by the player.) So the next controller inputs is completly ignored, because BizHawk skips the next inputs by the player, because "joypad.set()" has been used.
Suggestion: make a new function parameter for joypad.set(): (table buttons, [int ? controller = null], [bool ? skipNextPlayerInputs = true]). The purpose of "skipNextPlayerInputs", is: we can use joypad.set() with event.onframestart() without problem.

I'm not sure I fully understand your problem yet, but I wanted to point out that joypad.set() can take true, false, or nil as options. False will override the user input, whereas nil will not

If "skipNextPlayerInputs" is not defined when "joypad.set()" is called, the value of "skipNextPlayerInputs" become: "true".
If "skipNextPlayerInputs" is defined as "true", the function "joypad.set()" will skips the next player inputs. (This function already works like this)
If "skipNextPlayerInputs" is defined as "false", the function "joypad.set()" will not skips the next player inputs. (The next player inputs will overwrite the values defined in "table buttons")
If "skipNextPlayerInputs" is defined as "true" by default, we don't need to take care about: screwing up all existing Lua scripts that use joypad.set().
