It would be nice if Famtasia displayed the full 240 lines instead of 224. I don't know if it is possible to hack it to do that, but if it is, it would be good. - More details in movies - Some glitches in Rockman2 would be easier to abuse if one sees what's happening in the bottom of the screen.

We're in luck. It turns out that Famtasia was emulating the full 240 scanlines; it simply wasn't displaying them. Thus, the patch was rather simple. You can apply this patch directly on top of the 60-fps patched version. It's possible that I've missed a few spots in the patch, since the rendering routines are very spread out and there are a lot of rendering options in Famtasia. I'd like people to let me know if they find a configuration that isn't showing the full 240 scanlines. 
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
    FILE *fp = fopen("FAMTASIA.EXE", "rb+");
    if(!fp) { perror("FAMTASIA.EXE"); return -1; }
    fseek(fp, 0x1ff0d,SEEK_SET); fwrite("\xf0", 1,1, fp);
    fseek(fp, 0x1f352,SEEK_SET); fwrite("\xf0", 1,1, fp);
    fseek(fp, 0x1f2e6,SEEK_SET); fwrite("\xf0", 1,1, fp);
    fseek(fp, 0x1f389,SEEK_SET); fwrite("\xef", 1,1, fp);  /*fix*/
    fseek(fp, 0x1f2f1,SEEK_SET); fwrite("\xf0", 1,1, fp);
    fseek(fp, 0x1f34e,SEEK_SET); fwrite("\x3d", 1,1, fp);
    fseek(fp, 0x1f2e2,SEEK_SET); fwrite("\x3d", 1,1, fp);
    fseek(fp, 0x1ff31,SEEK_SET); fwrite("\xe0", 1,1, fp);  /*fix*/
    fseek(fp, 0x46920,SEEK_SET); fwrite("\x10", 1,1, fp);
    puts("done");
    fclose(fp);
    return 0;
}
Edit: Just noticed and fixed a small visual glitch

「６０ＦＰＳハック」は、できないと思いました。 「２４０ラインハックもできません」って思うが、デバッガを作って、何でもできる、ね。 Thanks again for the patch, blip. :)

If you're feeling brave you can try reading the code for clues on what to do in the hex editor. For example, the line: 
    fseek(fp, 0x1f352,SEEK_SET); fwrite("\xf0", 1,1, fp);
Means: "Set the byte at offset $1f352 to f0"

So, since we've been passing around the 60fps version of Famtasia, can someone hack and distribute the new 60fps/240 line Famtasia? Anyone?

http://babyamy.tripod.com/grinto/famtasia24060.zip (copy this address, rather than clicking it) Hopefully I got it right this time! Choose one of the default window sizes to update it to the new resolution. It doesn't work in fullscreen though, unfortunately.

I just edited my post and updated the patch to fix a visual glitch. Sorry, I was probably a bit hasty... I'll look into fixing fullscreen next.

[edited] It works fine at 1x... *snip* And now it works fine at 2x... But 3x is still glitched, it seems.

At this point the 240 version cuts off the top of every game I try, regardless of window size.

New patch. Supersedes the previous 240-scanlines patch. 
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
	struct
	{
		unsigned long offset;
		unsigned char before;
		unsigned char after;
	} patch[]=
	{
		{ 0x1ff0d, 0xe0, 0xf0 }, { 0x1f352, 0xe0, 0xf0 }, { 0x1f2e6, 0xe0, 0xf0 },
		{ 0x1f389, 0xe0, 0xef }, { 0x1f2f1, 0xe0, 0xf0 }, { 0x1f34e, 0x45, 0x3d },
		{ 0x1f2e2, 0x45, 0x3d }, { 0x1ff31, 0xc0, 0xe0 }, { 0x46920, 0x20, 0x10 },
		{ 0x1f5cd, 0xe0, 0xf0 }, { 0x1f5d8, 0x45, 0x3d }, { 0x1f617, 0xe0, 0xf0 },
		{ 0x1f60c, 0xe0, 0xf0 }, { 0x1f608, 0x45, 0x3d }, { 0x1f1ad, 0x45, 0x3d },
		{ 0x1f1b2, 0x38, 0x3c }, { 0x1f6e0, 0xe0, 0xf0 }, { 0x1f6dc, 0x45, 0x3d },
		{ 0x1f71d, 0xe0, 0xf0 }, { 0x1f460, 0xe0, 0xf0 }, { 0x1f478, 0xe0, 0xf0 },
		{ 0,0,0 },
	};

	FILE *fp = fopen("FAMTASIA.EXE", "rb+");
	if(!fp) { perror("FAMTASIA.EXE"); return -1; }

	int i;
	for(i=0; patch[i].offset; ++i)
	{
		fseek(fp, patch[i].offset, SEEK_SET);
		fwrite(&patch[i].after, 1, 1, fp);
	}

	return 0;
}
This adds fullscreen support. You might notice that the very top scanline has been cut off and an extra one placed at the bottom of the screen -- this is apparently a glitch in Famtasia's emulation. For some reason the x3 magnification is uneven -- not all the pixels are uniform in size -- but I'm not going to worry about it too much right now. :) I'm sorry that I released the previous version before fullscreen support was added. I dont know why it slipped my mind...

Blip, do you think you would be able to hack Famtasia in such a way that would let allow you to redo early parts of a video without having to redo the whole thing?

That's impossible to do, just so you know.
someone is out there who will like you. take off your mask so they can find you faster. I support the new Nekketsu Kouha Kunio-kun.

Remember causality 'n' consequence. If you really feel adventurous, make a backup copy of your fmv file, then start recording from the earlier position and finish when you're done, and copypaste the rest of the backup file to the end of your now truncated fmv file. All in a binary-safe editor of course.

Actually, I can think of a way to do it. You could embed save states in the movie file. I'd like to see it done just because it'd be a great tool for perfecting time attacks. But it arguably crosses the line to cheating since the movie files are no longer just controller input. It'd be an awful lot of work to hack into Famtasia. VirtuaNES would be more doable since they already have savestates in their movie files... but still not likely to happen I'm afraid. :/

blip, thank you very much. You're a genius :) I didn't test this new patch very thoroughly yet, but it seems to work. I just hope it doesn't overflow some buffer or anything :)
