=================================
StretchMAME 0.59 build 020404
=================================
(2002/04/04 release)


What is StretchMAME?
-------------------------------

StretchMAME is one of the clone MAME. It has the following features.
- Spurious motion-blur
- Blur-less stretching
- Spurious 3D view (keystone transform)
- Rotation, Expansion, Reduction

StretchMAME requires Direct3D. So you need 3D accelerator.


What is 'Spurious motion-blur'?
-------------------------------

Most arcade games do not have a translucence function. So they express
translucence by blink.
Then, spurious motion blur, this function mades true translucence by
compounding with the last frame.

This function is effective in the following game.
Quiz Nanairo Dreams: Nijiirotyou no Kiseki
DoDonPachi
Macross
Macross II
Mazinger Z
Altered Beast
Moon Walker
Alien Storm
Uo Poko

In the other games, shadows, lasers, and flames are beautiful.
Be attension, frame skipping makes hard to see. You need very fast PC.
Moreover, since DirectX7 is used, it does not work on WindowsNT4.0.


What is 'Spurious 3D view (keystone transform)'?
------------------------------------------------

It makes perspective view looks like 3D games.
In case you use this function, don't use windowed mode.



Usage
-----

This is a command-line version without GUI.(like official MAME)
At the first time, don't forget -createconfig. It makes INI file.

following options are added.

* -[no]spurious-motion-blur / -[no]smb
Enables or disables spurious-motion-blur.

* -[no]bilinear-filter / -[no]blf
Enables or disables bilinear-filer. When disabled (which is the default),
StretchMAME stretches without blur. You can get blur-less hw stretch.

* rotation
Clockwise angle of the screen.

* zoomx
* zoomy

* keystone-ratio

From video.c:


Code:

// added by smame
{ "spurious-motion-blur", "smb", rc_bool, &win_motionblur, "1", 0, 0, NULL, "spurious motion blur" },
{ "bilinear-filter", "blf", rc_bool, &win_bilinear, "0", 0, 0, NULL, "stretch with bilinear filter" },
{ "rotation", NULL, rc_float, &f_rotation, "0.0", -360.0, 360.0, video_set_rotation, "rotation(degree)" },
{ "zoomx", NULL, rc_float, &win_zoomx, "1.0", -10.0, 10.0, NULL, "zoom x" },
{ "zoomy", NULL, rc_float, &win_zoomy, "1.0", -10.0, 10.0, NULL, "zoom y" },
{ "keystone-ratio", NULL, rc_float, &f_keystone_ratio, "1.0", 0.1, 10.0, video_set_keystone, "Keystone ratio(U/D)" },
{ NULL,	NULL, rc_end, NULL, NULL, 0, 0,	NULL, NULL } 

I don't have the original settings I used back then when I took the snapshot but these seem to be pretty close (from smamepp.ini):



Code:

zoomx                   0.700000
zoomy                   0.700000
keystone-ratio          0.600000  

I wonder what smame is up to these days.
