HqxMAME - standard MAME plus support for hqx scaler

Hi,
I've been searching for a version of recent MAME with support for HQX scalers. But all MAME variants I could find were pretty much outdated. So I created a new one:
http://sourceforge.net/projects/hqmame/
It's a very lean implementation on top of current MAME 0.147, essentially can be shrinked-down to a single "diff" file with support for hq2x, hq3x and hq4x. (So it should be trivial to catch up MAME development in the future.)
By default the GDI version with hq3x scalers is active, but this can be changed via command line:
Usage:
hqxmame -hqx
scale:
1 = no scaling
2 = hq2x
3 = hq3x (default)
4 = hq4x
Best, Zenju

hqnx+xbr would be ideal
it would require a cpu that doesn't even exist to achieve 100% speed.
I'm happy with HLSL anyway.

There appears to be a license issue, on the main page it says the project is GPL and it not possible to link MAME with GPL code. I'm not sure that sourceforge will allow you to host source that is licensed under the MAME license.

It gives MAME one of those appalling edge detection filters that some people like.

Not sure about that:
First timings comparing a test suite with HQx, xBR:
2000 iterations, scaling factor 4
hq4x 6075ms
xbr4 1989ms
It's looking good...

Damn, I love this filter... The first time I heard about it half a year ago, there were apparent issues with distorting the image, but these seem to be resolved in v3.3:

it is sufficient to adapt the XBR code (cg shader) in HLSL to see lower resource consumption. I guess...^^

Good news: Just released version 2 of HqMame (not HQxMame anymore) with support for multithreading and the xBR-z scaler as new default:
--------
|HqMAME|
--------
Usage:
hqmame -scaler
name:
2xbrz = Scale by Rules, Zenju mod, factor 2
3xbrz = Scale by Rules, Zenju mod, factor 3
4xbrz = Scale by Rules, Zenju mod, factor 4 (default)
hq2x = High quality scaler, factor 2
hq3x = High quality scaler, factor 3
hq4x = High quality scaler, factor 4
none = no scaling
-----------
|Changelog|
-----------
Version 2.0 - mame0147
----------------------
Added support for xBR-z scalers
4xBR-z new default scaler
Take advantage of multi-core CPUs for both emulation and scaling
Set "multithreading" active by default

Great, but you do not think it could be even better if you convert the Cg-shaders version in HLSL, resource level that might be better? (except if impossible)

I'm not sure if it's worthwile. I don't think there is much of a performance problem left, and (for me) the hlsl code wouldn't be as convenient to maintain as C++.

BTW does someone think it makes sense to propose to include scaler support like this into standard MAME? I'm new to the MAME-dev scene, but from what I see in forum posts it seems, there are some ideologic debates about whether it is heresy to scale pixels or not. Given that it has taken me only about a week to include scaling support makes me wonder why standard MAME doesn't offer it as an option at least.

These scaling methods do not attempt to simulate the appearance of real arcade machines in any way (as e.g. MAME's HLSL framework does with the scanlines, phosphor triads, CRT curvature, etc, etc) so we are not interested. If you want to pretend arcade games looked like something they didn't that's your prerogative but MAMEdev is not in that business.

The GPL doesn't allow linking to mame source.

Okay, so I guess I'll have to add an exception to the GPL license.
