GS Mode Selector: Development & Feedback

[dlanor]

This flickering is also present on my 16/9 CRT build in the year 200X.

Yep. It is not a question of age, but of the technology used. So all CRT screens will show this interlace flicker.

Normally it shows no difference if any NTSC or PAL signal is used as input.

There is a small difference in the timing, as the PAL flicker frequency is 25Hz, with NTSC having 30Hz, but in other things the flicker is identical, in placement, light intensity, etc.

There is something that i think is not normal if i use GSM to set NTSC mode for FF 10-2 the shadows of the characters in-battle are only half shown.

One line shadow next one no shadow and so on. My TV has a feature of pausing the picture with this i can see that the shadow is almost normal. One time full shadow then no shadow and half shadow.

I see, and I can guess at a reason for it. This is possibly one of the cases where the two 'rectangle circuits' of DISPLAY1 and DISPLAY2 registers are used for different purposes. The main one generates the main picture, while the other one generates the shadow. But GSM always assumes that the rectangle coordinates represent the full screen, which might not be the case. We also always assume that the field/frame method must conform with the main vmode usage and smode2, but that is also not necessarily the case. Not for a shadow generated as a partial screen overlay.

It is a few weeks ago that i tested that so i will test that again with the latest available version of GSM.

Since v0.23d and v0.23e came out later, and use a different rule for DISPLAYx register patching than some previous versions, the results could well differ. If not, then please try with v0.23b as well, since that uses a different rule from v0.23e.

v0.23e patches both registers when calculating a value for either one,
while v0.23b patches only the register for which a value is calculated.

Neither one will work correctly for the shadows, if the reason for the problem is as I suspect, but there should be a difference in the symptoms for those two versions, and with the pause function of your TV you have a good chance of seeing that difference. But I also suspect that this pause function may average screen values from successive half-frames, so it is not fully reliable as indicating exactly what one half-frame generated.

hi there, but does GS Mode Selector work with backup games?

thanks

It does as long as your PS2 support them.
(If you use FMCB, or also if not) ...just go back to PS2-Browser/OSDSYS.

I tried many titles (compatible too), but always says: Insert a ps2 valid disk!!

I have a matrix infinity mod. with a ps2 slim last model.

Are you booting GSM through uLE??
If you have, try to use PS2Load inside uLE after choose the GSM mode.

dlanor, I'm thinking in new ways to use GSM, and occurs me a ideia. There's a way that just choosing the video mode and entering a screen resolution, the own GSM maybe could calculate the most perfect DX, DY, DW and DH for better adjust of the screen? It's not actually a request, it's almost like a (im)possible future feature. :P
I have noticed some games in 1080i or 480p get a reduced screen, like Kingdom Hearts series. Tweaking D values give a better result, but is hard to precise the ratio. Maybe a option to increase DW and DH maintening the ratio could be a improve to GSM. Well in these games, while the gameplay has a little reduced screen, the CGs got the correct size.

GSM does not in any way affect disc validation, so if you got that error with GSM you would also have gotten it without GSM, if all other actions were identical.

The Matrix Infinity is notorious for having a dysfunctional "sleep mode" which often prevents access to burned discs. Most likely your chip is 'asleep' and will not help with the disc validation. There are several things you can try to get around this.

1: Have the backup game inside the PS2 as you turn it on, and never open the disc tray/lid. Then the original validation made by the chip at turn-on should remain valid for game launch later on.

2: Disable chip and use FMCB to boot uLE, which you use to launch GSM, and then use ESR to boot the game as ESR-patched backup.

3: Use some non-CDVD media to launch the game, such as USB with USBAdvance or "Open PS2 Loader", or make a similar USBA-install with USBUtil to a PC HDD, and run the game from a fileshare there using the SMB interface of "Open PS2 Loader".

I think you meant "MISC/PS2Disc" here, which is normally good advice, except that it might still fail for an MI chip in 'sleep mode'. At such times the mechacon will perform the authenticity checks unaffected by the modchip, which will cause refusal to run a normal backup (not using ESR).

Yes, sorry for my mistake.

To enter under sleep mode just hold start during the boot. to awake, do the same thing, hold start during the boot. This is the button for 1.54, maybe 1.93 have a different button.

thanks,
I did this for GMS:
c) Bootable PS2 CD, you can do it putting the ELF file into a ISO image built by CDGENPS2

so what is the best way to avoid the sleep mode and make backup play?

This is not the best way. My Matrix Clone has some issues with opening the tray to change the disc, so I think this is your problem, even with the original.
Make a bootable cd with uLanuchElf, and open you MC, creat a folder called BOOT and copy a uLaunchElf.elf renamed to BOOT.ELF to inside this folder.
Your chip has DEV2, this means after you have a MC in slot 1 with a BOOT.ELF inside a folder BOOT you can launch it by holding R1 before the PS2 boot screen. Now put GSM in your MC too or in a pen drive and launch GSM through uLE, this time will work!
