Ico in 240p on LRPS2?

[Dooberknob]

Is it possible to run Ico at 240p? My understanding is that this one of the few games on the PS2 that outputs 240p, but when I set the resolution to native, LPRS2 runs it at 480p. fwiw I get the same behavior from PCSX2 standalone as well.

That’s funny, since 240p is usually used so they can do 60 FPS (instead of 30 FPS with 480i), while that game often drops to sub-10 FPS lol

Anyway, I assume the core is line-doubling it, so you should be able to safely downsample it with shaders. I would try crt-hyllian-3d first.

ICO not running in 240p in standalone PCSX2 is curious. It makes me wonder if this game is doing anything special, or if the 240p resolution is something of a myth for this game? For LPRS2 resolution behavior, I opened an issue on github:

Native resolution / scaling bugs

Ok, after looking into it a little more, it turns out Ico running at 240p is a bit of a half-myth. The PAL version is 240p, but the NTSC versions are 480i. Luckily, the PAL version also gives the option to select between 50hz/60hz when it boots up.

I do this on Linux Mint by setting resolution at 640x240 on a vga crt monitor and run retroarch. It also works on PCSX2

Aha, very nice that you found this out.

Anyway, on CRTs it’s not a problem achieving 240p when setting resolution manually (and not trying to use switchres in this case I suppose). For shaders, I’m an advocate for the res-independent scanlines shader from the “scanlines” folder.

It’s also possible to downscale via stock:

shaders = "1"
feedback_pass = "0"
shader0 = "shaders_slang/stock.slang"
wrap_mode0 = "clamp_to_border"
mipmap_input0 = "false"
alias0 = ""
float_framebuffer0 = "false"
srgb_framebuffer0 = "false"
scale_type_x0 = source
scale_type_y0 = source
scale_y0 = 0.5
