For deinterlacing there are lots of filters available (e.g. Yadif or QTGMC), but in this case a simple blend is better.
This is in AviSynth what FODA did:
It's somewhat like Super Metroid where you can rescue some trapped animals so that they can get to their own space ship. IIRC they don't have to be rescued in a 100% run, even though they appear in later games.
Personally I'd like to see Marin though. :)
If the video is encoded with a "simple" codec like CamStudio then it should be frame-accurate. Otherwise you could use DSS2: Get the Haali Media Splitter, create a file named "DSS2.avsi" in your AviSynth's "plugins" directory and enter this function:
Each file is named "sm64.XXX.avi" where Xes are digits, but there can be 2 instead of 3.
Renamer or a similar tool could convert the filenames.
Instead of AVISource you could try DirectShowSource. As for generating the script, I'd open Excel and write something like
..., select these six cells and drag the lower right corner down until there are 116 lines. Then select all, copy&paste it into a text editor and replace the tabulator characters with nothing. Then remove the last "+\".
Result
If you want to encode the RGB/WAV streams to something smaller: Open the video in VirtualDub, choose the x264 codec for video compression, choose the LAME ACM/DS codec for audio compression, (configure them) and save.
Incidentally, about games that use frame blending, I intend to find a method of only doing it for specific segments of a TAS (Which should either minimize the problem... or make it even more obvious). Though, the method I have planned out so far is highly manual and won't work well for longer TAS's (Unless you really have the spare time).
If you want to do that, the code could look like this:
AVISource("00a.avi", "00b.avi", "00c.avi")
ConvertToRGB32
GaussResize(640, 480, p=66)
ConvertToYV12(chromaresample="lanczos4")
#m1( 0, 4000) +\
#m2(4001, 4100) +\
#m1(4101, 8000) +\
#m2(8001, 8100) +\
#m1(8101, 0)
function m1(clip c, int i1, int i2) {c.Trim(i1, i2).ChangeFPS(c.FrameRate / 2)} # method 1
function m2(clip c, int i1, int i2) {c.Trim(i1, i2).BlendFields } # method 2
function BlendFields(clip c) {
c
Overlay(SelectEven, SelectOdd, opacity=0.5)
}
Go through the video and add lines with m1/m2 until you have all spots covered, then uncomment the lines.
Btw. BlendFields uses Overlay which internally works in YV colorspace, so to avoid conversions call it after converting to YV12.
The clip given to BlendFields should have an even number of frames; I don't know if it'd work correctly otherwise.
For some games it's useful - for example Metroid's and Super Metroid's elevator sequences.
IMO somewhat a bad example cause those areas have no action, and skipping frames during those parts is not like you missed something. It's just Samus moving up and down!
I tried using the Alpha, but there was only an incomplete release at sourceforge. :/

Well, the yellow/orange gradient is smoother in the bottom one.
EDIT: Comparison between lq2x and hq2x:

Top right and bottom left is lq2x; bottom right is hq2x; top left is differences.
It must be noted, that blurring just for YouTube to keep all frames makes the video a blurry mess. It's a bad idea to do IMO. I rather drop frames and see the movie sharper.

Mister Epic:
"file" should be "path" and "b" is not defined (line 3). Are you using a newer AviSynth than 2.5.8?
