[ISSUE]: SCPH-90000 not forcing PAL games into NTSC video mode #237

Describe the issue

Hi. According to the documentation, the DEX option "[forces] NTSC-U region and video mode for PS2/PS1 titles". I have a Cinnabar Red SCPH-90000 that I tried with several different DEX options, and PAL games still output at 50hz.

Deckard models are listed as being "SCPH-750xx - SCPH-900xx models + Sony Bravia KDL-22PX300 tvcombo". Based on this I'm assuming my unit is a Deckard model, but I'm not sure how to check conclusively.

Am I doing something wrong?

@vraskin2024 it also depends on the game you play. Some games uses video mode that is set inside console, some games even can set up language automatically. But some games ignore those settings and set up video mode whatever they want. For example, almost all PS1 games do not setup video mode and only uses the video mode that console is using (very few exceptions, I think some Ace Combat). While the PS2 games is dong it in different way, almost all games ignore console video mode and sets up whatever they want. If you want to change game videomode you need to use some 3rd party programs, like gsm or ps1vmodeneg.

Oh interesting. That's a bummer... I was hoping it would work the same way as the old Matrix mod chips where it could force the video mode on everything. I think you're probably right that's the issue though - I tried some PAL PS1 games and they display in 60hz on the MechaPwn unit.

I actually have another slim with an original Matrix mod chip. The PAL PS2 game I was testing with is 50hz on the MechaPwn unit and 60hz on the Matrix unit.

Out of curiosity is there a way to visually determine if a unit is Deckard or not by looking at the motherboard? What IC would I be looking for?
