I have Modbo chip and composite to vga cable Also SOG support Monitor.if i Enable VGA option in Modbo then every thing work fine hdd loader and most game work with this option but on am using OPL and play game from PC but OPL is Hang with modbo chip, so am going to remove chip from ps2, is there any other hard mod to play game to vga monitors. Remeber hard mod not soft mod like GSM Selector.

well you could try to disable or Turn Off the Macrovision in the MI Menu.i dont know it might work

If you just have a little patience, OPL v0.7 will soon be released, and this version has no problems running with normal modchips (that works fine with current OPL beta versions). So then there is no reason for you to remove your modchip and abandon your old VGA methods.

So if you can just be a little patient a little longer, this problem will go away of itself...

any Alternate method to play non progressive game on VGA without chip,also take V and H sinc on ps2 mother board(300xx) directly but its only work with progressive game ,is there any IC or chip require to display non progressive(15Hz) game on VGA(30Hz).any home made converter


Thanks in Advance


@dlanor can GSm selector boot HDloader auto without change any screen option and press start+back or forward, every time when i boot GSM ?

Sorry, but I don't follow your meaning. There are NO progressive games for the PS2.
Some very few games allow for use of a progressive mode as an alternate to the normal ones.
But such game features are very, very rare...

I suspect that you may be confusing the terms "interlaced" and "progressive".
Normal PS2 games are interlaced, though some use a non-interlaced mode.
But I would hardly use the term 'progressive' for them, as they still follow normal PAL/NTSC standards for all signal timing.

In a way progressive does imply non-interlaced, so 'non-progressive' would thus mean the same as "interlaced". Perhaps I'm just being old-fashioned, but I constantly get the feeling that a lot of the 'new terminology' was invented mainly for marketing purposes...


In any case, getting back to the meaningful gist of your question, there are ways of forcing games to run on a VGA monitor, but the quality at which they run (sound sync etc) will vary for different games and for the precise choice of VGA mode alternatives. Such means include GSM which you are already somewhat familiar with.

A particularly frequent requirement with such methods of VGA enforcement is that games designed for real use of PAL/NTSC interlace methods will require an interlaced VGA mode for display on a VGA monitor. Otherwise the game engine may malfunction in those games.

In addition to such methods as GSM, it's also possible to use external converters (the best being VERY expensive).

,is there any IC or chip require to display non progressive(15Hz) game on VGA(30Hz).any home made converter

Again, I don't know what you have been smoking here , as I never heard of any 15Hz video signals in my entire life, nor any 30Hz ones either, unless you are talking about the full-frame rate of a normal NTSC signal, since the half-frame rate of that is 60Hz.

Normal PAL games have a half-frame rate of 50Hz when interlaced, thus a full-frame rate of 25Hz.
Normal NTSC games have a half-frame rate of 60Hz when interlaced, thus a full-frame rate of 30Hz.

When used for non-interlaced video, these become full-frame rates of 50 and 60 Hz respectively, as the VSync rate in both cases is constant.

As for making any normal VGA monitor accept a 30Hz VSync, that is simply not possible for any monitor I ever heard of. Generally they use higher VSync rates than SDTV signals, though most allow for a standard 60Hz VGA mode as the one with the slowest VSync. And when driving that input with an interlaced signal the result is a full-frame rate of 30Hz. This mode is in fact very close to normal NTSC in timing, and GSM emulation using this mode should allow virtually all NTSC games to work well.

@dlanor can GSm selector boot HDloader auto without change any screen option and press start+back or forward, every time when i boot GSM ?

No. The auto start can be arranged, but GSM has no ability to fake gamepad button presses for another program, and such a feature will not be added.
(It would inevitably cause many games to bug out.)

Dlanor, Khz refers to the horizontal pixel rate.

Interlaced refers to the fact that on Standard Definition displays, due to bandwidth restrains video data is encoded on an ODD/EVEN lines scheme, making use of the persistence of vision effect.

Progressive means that no ODD/EVEN scheme is used and all and all the screen is drawn in a single step (hence the name progressive...) this is what HD (High Definition) Television sets and computer displays use.

Because the progressive mode sends twice the bandwidth per frame it uses an horizontal transfer rate of 31Khz. The vertical refresh may vary from 30hz to 200hz depending on the display application (I believe the most a high end CRT display can do is 150hz)

So, the guy wanted to mention the 15khz/31khz thing but he missed the Kilo.

Also it's interesting to see how the PS2 graphics chip was designed to operate on HDTV frequencies from the very beginning but the software was not. If SONY really wanted to it could push the PS2 a bit further than they did. They prefered to scrap it and mve on to the PS3 instead... lol

Yes, of course it does, but I didn't see that unit used anywhere. Only Hz.

Progressive means that no ODD/EVEN scheme is used and all and all the screen is drawn in a single step (hence the name progressive...) this is what HD (High Definition) Television sets and computer displays use.

Again I have to say: Yes, of course.

Sure, but there is also little point in aiming too high with the refresh rate, as a human being can't notice very fast visual changes anyway. At least not with those cells in our eyes that receive colour information, as they are slower than the cells that merely register luminance.

So, the guy wanted to mention the 15khz/31khz thing but he missed the Kilo.

Yes, now that you mention it I do realize that he meant the horizontal rates rather than the vertical rates, which I automatically assumed when he used Hz units rather than kHz.

I suppose I should have seen what he really meant myself, but as usual I was making my posts towards the end of a looong day(s), and I'm not at my best at such times.

Also it's interesting to see how the PS2 graphics chip was designed to operate on HDTV frequencies from the very beginning but the software was not. If SONY really wanted to it could push the PS2 a bit further than they did.

That is very true. There is a lot of unused potential in the PS2 console, which only a few of the latest generations of games began to use a little of, though none ever attempted to use it all (or even close to it).

They prefered to scrap it and mve on to the PS3 instead... lol

Yep, and after that they have continued to make one bad PS3 related decision after another, until we arrive at the current mess with at least 3 class-actions suits against them and most likely with more of the same to come...
