Groovymame 15khz modelines and Adjust timing Questions/help
Zebidee:
With XP you will be limited to MAME v0.180 or thereabouts, whatever variant you use.
Groovymame is the best for framerate matching and speed accuracy - should be no "screen tear" lines at all.

Hi :-) for info Arcade32 version 0.245 works without any problem on Windows XP-32. and it even works very well.
I just did a test with Windows 7 + Groovymame and I get exactly the same results in "timing".
Groovymame does a great job, the modeline values taken from the Mame source code are respected, but that doesn't mean your hardware will interpret things that way! you have to touch up the modelines if you want perfect timing. It depends on the material. Most older generation graphics cards use multiples of 8 horizontally (this is the VGA standard). The resolution / modeline information taken from the source code of Mame does not necessarily use multiples of 8 so it will result in artifacts, jerks on the screen and loss of sound sync, and therefore it is necessary having recourse to Triple Bufering, V-Sync and other filters of this kind which induce lag.
However I have never tried with newer gear.
home hardware differs from arcade hardware. Arcade gear tolerates larger values, so unless you have a real graphics card that accepts timing differences of more than 3 decimal places + no constraints in the numbers of the number of horizontal lines, yes, but personally I've never had the chance to test a graphics card of this type.
Information on this subject is rare on the web, I have the impression that most people are content only to have a beautiful image and beautiful scanlines but they do not seek to go further. Personally, what I like is the timing, I want something to respond to the joystick! I do not care if the image protrudes from the screen or not, or if the game runs slightly faster than the original, no, what I want is perfect fluidity, and for that you basically have to find the perfect modeline is the basis for obtaining as little lag as possible. then we see whether or not to use a filter.

Hi,
I don't understand your last post. Groovymame matches exactly timmings freqs and resolutions if you have a compatible gpu card, from switchres 2.0, this happens without any installation of modelines with super or native resolutions, all is needed is a crt_range.
I don't know about Arcade32, but seems he hasn't same target than Groovymame.

My comment was never intended to mean that it is impossible to run MAME past ~0.180 on XP. More that you will be "limited", it won't work out-of-the-box, without hacks. Arcade32 is a version specifically hacked to run on older hardware, so an obvious exception.
I myself am running a hacked version of Groovymame 0.200 on XPx64 machines with older video cards.

I did the tests with Groovymame 64 216 I see that Switchres is older it's version 0.017 but it didn't suit me so I went back to XP-32

Sorry, I misunderstood :-)
Well do you also encounter the same problem as me on XP64 with resolutions 321x224 and 321x240?
I came back to XP32 and I use the Custom Build Groovymame32 0.211 version because with this version you can save the values of the Sliders for the refresh rate and the CPU sound overclocking.
I tried more recent versions of the custom builds but they don't work from 0.212 it doesn't work under xp32 even though they were compiled for that... even the official Groovymame32 0.227 XP32 version doesn't work on XP32 SP3.
cannot launch system compatibility error.
I'm currently having fun testing Groovymame 0.211 in combination with soft15khz on an Nvidia MX 400 card and it works great, the rendering is great, better than with Arcade32. it allows me to use Frame Delay. good Switchres does not work, I am limited to 32 modelines but it does not matter because it is me who manages all the ini files + my modelines + I adjust the slider refresh rate.
