I was wondering if there's a way to run the movie file up to that point, then somehow take control again and do that to replace the commands in the movie file. How can I do that?

Play it in read-only mode up to point you want and then switch to read-write mode and continue from there?

Playback the movie with read-write enabled to a point you want to continue, save a state, then load this savestate.

how to switch to read-write? also, won't that desync the video prior to this point?

With an hotkey, or set it in the movie play-back dialog. FCEUX is very stable, it won't desync.

I have a request too. VirtuaNES has a nice "Double Size Rendering" option. Can you add it to FCEUX please? Most of emulators upscale NES original resolution to current resolution using linear interpolation, so output image looks too blurry. The "Double Size Rendering" option upscale NES original resolution to 2x (nearest neighbor), and then upscale 2x-image to output resolution with linear interpolation. Look at screenshots: Raw stretch to 1920x1200 DSR on DSR off (the most common and blurry)

I found a bug with Tengen Tetris in this emulator. When pressing down while selecting level/handicap, you go down 2 spaces, making the selection of the fastest level (level 9) impossible unless you start from level 8 and score enough lines to go to level 9.

Are you sure you don't have both player 1 pad and player 2 pad up/down mapped to the same key? The game uses both player 1 and player 2 controls for the menu, and if both press up/down at the same time, it causes a 2-space step.

Ah, it was the controllers having the same input! Plus this was used in the 30 Lines TAS. Nice catch!

i cant for the life of me figure out why no one seems to care that FCEUX, the best emulator for NES (for TAS and otherwise) does not have the option for scan lines!! this is madness! call me a stickler but i just gotta have more scanlines, baby! if theres a secret way to enable this option, hallelujah, and let me know how! if there isnt, then is it even on the list of things that are "coming soon"??? anyway it's got my vote. i hate to mention a different emulator in this thread but nestopia's scanline options are to die for! theres a slider bar that lets u control how much of the scanlines u see. its freakin awesome. cuz most emulators only have 1 or a few settings. this one lets u dial it in to exactly how u want it. if FCEUX had this feature it would be UNSTOPPABLE (i wouldnt be able to stop playing anyway) basically to sum it all up in one word: SCANLINES!!!!!!! AAAAAAGHHHHHHH!!!!! ok two words

I've never seen scan lines done well but it's been at least 10 years since I've looked. What you really want to do is simulate the physics of a CRT, and you're going to need a boat load of pixels to get there. Bonus points if you simulate the losses of different wiring setups, notably RF cabling.

If you want to pretend you're playing on a CRT, there's always this ultra high quality CRT filter: http://board.byuu.org/viewtopic.php?f=10&t=147

His end result isn't bad, but I consider it to be the wrong approach. I'd love to see something that ray traces the pixels as if from an electron gun to where they'd collide on the curved screen. e: I wonder if 60hz would even be enough?

i am very interested in this high quality CRT filter but cannot see where to download it or how to implement it in FCEUX from the link...am i missing something obvious?

also another thing that would be great would be if you could map hotkeys to buttons on your gamepad. how am i supposed to press pause then pick up my gamepad to play without that dead time appearing in the video im trying to record?? do i have to have a friend press pause for me? or use my toes?? cmon!!!

You can record your input and later replay it while capturing, so pausing is not visible. You are encouraged to use the inbuilt a/v capturing facilities for that.

All syllogisms have three parts, therefore this is not a syllogism.

i am aware of how to make recordings and to change from read only to read/write and to be able to step one frame at a time and do everything perfect but at the time when i want to simply unpause and keep going in the recording, i have to press pause on the keyboard and then pick up my game controller and it would just be so much better if i could map the pause button to a button on the gamepad! yes if i am using the keyboard and going one frame at a time its not a big deal but if im trying to use a gamepad and u know..actually play the game, i have to keep putting it down to press pause and picking it back up. its annoying and wasting time in the video! unless there is some simple thing im not understanding... enlighten me please!

Can someone tell me if there is anyway to record avi movies with this emulator and have the resulting video with the ntsc 2x filter, I've tried numerous things and no matter what I do it refuses to use anything other than the standard.

There doesn't seem to be a way. You can use an external capture program (like Fraps). Or, if you know how NTSC filter works, then you can dump AVI from the emulator, and apply the filter in AviSynth. I don't know anything else.

If you really want scanlines you could use BizHawk which has options for scanlines (you can even adjust how much your want) and is in very active devopment. If no one has a solution for FCEUX then you could try this...

Is there a way to change the base directory, command line being preferred, in the SDL version? I see directory overrides in the help documents but can't locate this anywhere in the program.

I've tried to make "NTSC-slowdown to 50Hz" mode instead real dendy mode. fceux-2.2.2-src fceu.cpp, line 930 before changes

int32 FCEUI_GetDesiredFPS(void) {
	if (PAL)
		return(838977920);  // ~50.007
	else
		return(1008307711);  // ~60.1
}

after changes:

int32 FCEUI_GetDesiredFPS(void) {
	if (PAL)
		return(838977920);  // ~50.007
	else
		return(838977920);  // ~50.007
}

So, i've replaced PAL constant "838977920" to NTSC-mode. Slowdown works correctly and NTSC-mode run at 50 FPS, but sound is totally broken and distorted now. How can i fix it?
