|
> [!IMPORTANT]
|
|
> **Video Signal Note:** This modchip does not handle PAL/NTSC video signal conversion. Playing games from a different region may result in an incorrect display (e.g., NTSC games on early PAL consoles, or PAL games on NTSC-U/C or NTSC-J consoles).
|
|
>
|
|
> *Note: European models from SCPH-7002 onwards typically handle NTSC signals correctly without display issues, but SCPH-102 requires a BIOS patch.*

>
|
|
> See the **NTSC/PAL Display Mismatch** example at the bottom of the page.
