Converting Japanese PSone to PAL

[KarimPolska]

Hi guys,

Got many consoles from Japan and having tons of issues modding them.

As there is no shortcut to get them to read PAL retails nor backups i had to replace the bios...

Now the new bios from a pal donor pu-41 boots in black and white while the signal is cutting off...

Mainly because I don't actually know the answer to this question. I can give you an educated guess based on other systems I've worked with.

For the image being cut off, that might just be your TV's overscan setting perhaps? As for black and white, the color subcarrier is wrong (basically, and this is a guess, you might be outputting something like NTSC-50, not PAL, which not many things actually support except old American TV's with a vertical hold knob). But, I'm not qualified to answer this.

Even my American SCPH-5501 when put in PAL mode, is black and white and looks identical to yours despite my bedroom TV being multi-standard capable. It just can't decode the color burst at all, it's basically incoherent to it.

Basically, there's more to it than a software switch to go from NTSC to PAL, there's a color burst frequency as well since you're using baseband video (composite). If you used RGB however, it *will* be in color. That much I can confirm. But still with the cropping, if it's not the TV, someone else will need to chime in.

Again, I could be wrong as I simply don't know the PS1's video output quite like I do with most 8 and 16-bit platforms which is why I refrained from answering. I'd rather be silent than give the wrong answer.

Have you found a solution?... I had a similar problem when I modded a Japanese PS1 to play PAL games. One thing you can try is to check your console's video output—is it outputting RGB properly? If you're using a Composite cable on a PAL monitor, this could be the problem. A simple solution is to use a SCART RGB cable or try a monitor that supports both NTSC and PAL.
Have you tried this?

Regarding the image being cut off, it could be due to your TV's overscan setting. As for the black-and-white display, it might be an issue with the color subcarrier. My guess is that your output is something like NTSC-50 instead of PAL, which is not widely supported except by older American TVs with a vertical hold knob.

Even my American SCPH-5501, when switched to PAL mode, appears black and white—just like yours—despite my multi-standard bedroom TV. It seems that the TV simply cannot decode the color burst signal correctly.

Switching from NTSC to PAL is more than just a software adjustment; the color burst frequency plays a role since you’re using composite video. However, if you switch to RGB, the image should display in color. That part I can confirm.
