First; I'm not much of a coder and this is mostly idle musing as I avoid studying for my mechanics exam on friday. But, the PSX recording plugin someone else mentioned got me thinking. It works by recording the data the emulator sends to the graphics plugin to a file which you can then replay using a plyaback program and the relevant plugin. This file grows very large, since it's basically uncompressed graphics data, playing it all back is somewhat cumbersome and distributing the lot is generally unfun. However, PSEmu and compatibles (usually) also rely on plugins for controller data. Shouldn't it be possible to write a similar recording wrapper for the input plugins with relatively little fuss? I guess the viability of this'd depend on the data structure used by the plugin systems (i.e. on whether or not the input plugin knows what frame it's sending input for and so on - I imagine that just dumping the entire data stream could give horrible sync problems) and it's all far beyond my meagre coding skills to divine, much less do, but it might be interesting for one of the resident board code-monkeys to take a look at. 'course, as this is such a brilliant idea, I'm sure someone else must've already thought of it and concluded that it won't work :) - but, if some coding-competent nesvideos readers have time over this summer, this might be a useful way to spend it.

The only problem with that is Playstation ISOs are much harder to come by then these older console ROMs.

Emulators handle reading from CD-drives just fine, no need for an ISO. Granted, it's not likely that anyone who feels like seeing the run rushes out to buy a copy of the game, but it is for that they have nice, kind sites like Bisqwit's and SDA distributing movies. But foremost, it'll be difficult to produce tool-assisted PSX runs in any format before someone makes an adequate tool for creating such runs. Besides, it's not /that/ difficult to find PSX games in iso form, which is either sad or fortunate depending on ones outlook.

Well... PSX afaik has no plugins which create a *.PMV (naming convention used for ease). Having the plugin use - as you said Xerophyte - a logging mechanism to capture controller data would be much better than a raw AVI capturing plugin for easy distribution of "movies". I think PSX movies might be the limit for ease-of-use... considering generally the closer to now you get with videogames, the longer they have become.

well here is what i have found so far, although i only got to play with it for about an hour. i was playing with epsxe. so far what i have found is that it runs much slower then realtime (proly at about .7 speed or so) but the recording looks really nice. i am also haveing trouble with sound (on the emulation) it gets the standard sounds, but isnt playing any of the background music (this is for c:sotn so the music is kinda important). this is proly just cause i dont have the right sound plugins and whatnot. i assume when people refer to re-recording that is something that allows you to go back to your savestate and record from there, and i cant find a way to do this so far. so if anyone else has more free time then me, here are some thing i would like help figureing out: 1: how to get my sound working 2: how to get it to play, or at least re-play at 100% speed 3: how to get the record process to cut out the video for when you go back to save state(as in the section of video that I messed up on and dont want on my recording :) just for some background here are the basic specs on my pc (nothing great wich is proly most of my speed/sound problems): athelon 1800+ gforce4mx soundblasterlive 768 mg ram thanks in advance for the help, and ill keep you guys updated when i get to work on this more

You have a much more than powerful enough computer to emulate at 100% or more with no problems. You just need to configure everything right and use the right plugins.

What he have is good enough to emulate that old PSX.

The movie recording plugin also has a sound plugin that must accompany it. Make sure that's set up, if the only time you're not having sound is during the replays.

Really? I guess I'm a dolt, because I spent weeks scouring the Internet looking for Castlevania: SOTN before giving up and buying a greatest hits version. My problem thus far has been recording the sound without slowing the emulation.

ok so here is what i have found so far. i am able to use darkmans recorder to do many useful things. it is able to handle following save states if you enable demo maker recording in the options. this makes recording a speed run extreamly easy. here are some problems i have found with it so far: it takes lots of hard drive space (about 65 meg per minute). as of right now i havnt found a way to get it to record everything. it will cut stuff out when you play it back, such as some wepon movement(it will just not have the wepon there), lots of times it will cut out words, doors, my familiar, and stuff liek that. sometimes it dosnt even record the background and i will just have my charicter running around with no background. so basicly unless i find a way to get it working better with that stuff,t his just isnt going to work for a good video even if i can find a good way to convirt to a good video format (like avi or divx). anyway, ill play with it some more and let you guys know

I've also seen similar problems with this as well. Pressing escape to pause the emulator also ends the movie, and I believe loading savestates out of order does this as well.
