Sony has released a patch that attempts to improve the PS1 games of the new PS Plus at 50Hzbut users report that the effect it creates it is distracting.
Complaints were raised last week when the PlayStation 1 and PSP games have started appearing in PlayStation stores in the Asian regionbefore the launch of the new PlayStation Plus in Japan, the Americas and Europe in June.
It has been reported that all games from the first PlayStation included in the service they are based on the European PAL versionseven in regions that use the NTSC format, including Taiwan.
This means that the gamesi run at 50Hz instead of the faster 60Hz refresh rate of NTSC, making them significantly slower. Following this, Sony has now released a patch for some of these games, claiming to have “improved PAL output“.
However, as Twitter user Windy Corner TV points out, the patch creates a noticeable ghost effect as the screen scrolls. The patch appears to attempt to increase the 50Hz output to 60Hz to run its PAL games at the same speed as 60Hz games.
Sony has released a patch for a few PS1 Classics on the PS4 / PS5 that “improves” the PAL output.
The patch upscales the PAL code to 60hz by blending frames.
But the technique has introduced these horrible ghosting artifacts.

However, to do this, it appears to add the missing frames by merging the existing frames togethercreating a “ghost” effect. The problem was also highlighted in a Digital Foundry video, in which reporter John Linneman intended to analyze PS1 emulation in general, ma received the patch shortly before the video was completed:
They added frame blending to try to compensate for the PAL frame rate, but that means there’s a ghost trail behind each frame. This does not compensate for the low refresh rate of these PAL versions.
While Sony hasn’t officially confirmed why it’s using PAL versions of its games, it’s believed to be because include support for multiple languages. However, other third-party games on the service such as Tekken 2, Siphon Filter, Abe’s Oddysee And Mr. Driller they appear to be based on the NTSC versions.
It is also unclear whether all regions will receive PAL versions, although when the PlayStation Classic mini console was released in 2018, about half of his games used PAL versionseven in units sold in North America.
