Black borders (up and down) recalbox 8 + pi2scart + crt

@0zzy
Hi,
If it happens only on a few games. It could come from the "zone" of the game (Pal/NTSC).
Could it be 50 hz ones ?

Have you tried it on Recalbox 7.2.2 too?

[0zzy]

Hi @greenalex i have done some test, i think you are right, i'm using a no-intro romset, european games have black borders top and bottom, USA not.
What can i do in this case?

[0zzy]

hi @wizzard sorry i don't remember, i have tried a lot of distro and romset recently

[0zzy]

@greenalex have i to edit system.txt like suggested here ?

The exemple is for ntsc games, what can i write for pal?

@0zzy CRT timings are all sets in respect to the original Hardware timings. This means, the top/bottom bars are the same on the original hardware.

Since NTSC games use less horizontal lines than PAL games, you'll often get top/bottom bars.

Hi @bkg2k , i have black bars on PAL games not on NTSC (pal image is also a little bit streched, we are talking about 3 cm video, not a few pixel lines)

I use the same romset on a PC with crtemudrivers and retroarch, PAL and NTSC games works both fine in a full screen CRT monitor

@0zzy yop o/
Pal games are starting in PAL mode 50HZ like on the original pal hardware :
there was black bars on pal games, as the mode was 288p with 224 or 240 pixel height games.

We are working on a option to select the mode of pal games when starting it : PAL or NTSC.

Just not implemented yet.

If you search well in the wiki, you can override modes : https://wiki.recalbox.com/en/tutorials/video/crt/recalbox-on-crt-with-scart-dac

Hi @digitaLumberjack, from all this, i have understand NTSC games are visualized correctly but not PAL games, right?

i have seen this link a few post above, but, i don't have clear... there is an exemple:

if i need to lets Recalbox load PAL games, i have to write on system.txt something like

snes,pal, ???, 0, 0

is it right? how recalbox recognize pal and ntsc games?

If we can use system.txt why are you working on a option to select the mode of pal games? I have a lot of confusion now..

[0zzy]

snes,pal,snes:nes:pal:240@50.0069,0,0

is it right for system.txt?

[0zzy]

Can someone explain me the meaning of the mode:

1920 1 80 184 312 224 1 9 3 24 0 0 0 60 0 39001717 1

[0zzy]

@digitaLumberjack can someone explain me why i can't play pal games on a pal tv, really i don't have clear this

[Wizzard]

@0zzy I have not a solution, I just noticed that I cannot play PAL games for Atari 7800, they just do not start, I dont know why.

About your question, you mean that you cannot play PAL games on full screen, right? I remember that some PAL Atari 2600 games are bad conversion that only use a part of the lines of PAL system, it means they are in NTSC resolution but displayed in PAL standard with higher resolution.

Do you have a problem with just few PAL games or all ?

PAL games or all ?

Hi @Wizzard, yes i have this black borders on the top and bottom of the screen only on pal games.
As @Bkg2k and @digitaLumberjack say, the problem is the different refresh rate and resolution between pal and ntsc games, but i don't understand why this happen only on crt tv and not on lcd screen (on a normal lcd tv i can play both using batocara).
I was tryng to understand if i can manually bypass this, editing system.txt and a modes.txt, , so i can play pal games insted of ntsc, but i don't know how interpreter that mode line as i asked a few lines ago.

[Wizzard]

@0zzy OK, and does that problem occur on all PAL games or just a few PAL games? I am trying to understand, cause I will apparently have similar problem in a few days after I get my pi2scart.

Hi @digitalLumberjack , has been solved in Recalbox 8.0.1 ?

[digitaLumberjack]

@0zzy yes the feature is present in recalbox 8.0.1, still experimental though. Enable the region selection from the crt menu.

Hi @digitalLumberjack , i have enabled "select game refresh rate at launch" but snes games still have black bars,
is there anything I can do to fix it?

[digitaLumberjack]

@0zzy do you start them in 60hz ?
