Yeah, I can get the Neo Geo working in 3x mode, but I just felt like using the tweaks suggested in the op may be messing with the ratio somewhat? I could be wrong, it just looks like a different ratio to the the 4:3 mode my TV produces in x2 mode and my Mega drive using x3 using the tweaks in my post above.

I am not sure which is ‘correct’ mind, as I don’t have access to a CRT to compare! And I presume this kind of thing can vary from console to console? There’s certainly a lot of overscan area on an AES!

Thanks for the explanation Steo, appreciate it.

Interestingly I just picked up an NTSC Neo Geo AES and it doesn’t work with the above settings. I had to change it to 256 v.active as per the OP. Your settings in the linked list above also work. The only problem with this is that it seems to result in an incorrect aspect ratio.

I can modify is slight using h.samplerate, but eventually I lose the picture before I can rectify it fully.

The aspect ratio seems roughly correct in x2 mode, but way off in any combination of x3 mode I use.

By changing the h.samplerate away from the default are we always going to be changing the aspect ratio along with it?

I’m hoping I can get PAL working too, but I’m a bit confused about how what all the different settings do. Is there a beginner’s guide for people like me who have no idea what they’re doing? 😉

The OP seems to suggest that changing the H/V actual will affect the output Res. Is that the case?

I sourced a 60hz Megadrive (262p) and got it working in x3 mode on the Panasonic FZ802 with the following settings:

Generic 4:3
H sample rate 1221
H synclen 88
H back porch 130
H active 960
V synlen 3
V back porch 15
V active 240

Hopefully useful to someone. Most of those were left as default or tweaked slightly to get a better picture, changing the H sample rate to some random number was the key to getting a picture at all.

The benefit to this is that I can play with game mode on because the OSSC sorts out the ratio 🙂

I’ll report back if I get 313p working, but I doubt it.

By various, you mean specifically the PAL x3/x4 tweaks in the OP, or something else?

Yeah, I’ve tried the settings for x3 and x4 PAL in the OP.

I’ve also tried Marqs’ setting here

Those are for an EZ950 which is a very similar TV. However they’re for NTSC so I doubt they apply here 🙁

The display is showing 313p ~50hz and 1280×288 (x4) or 960×288 (x3).

Thanks for your help anyways, the TV can do 4:3 but it introduces some nasty lag. Better than nothing though!

[VinegarJoe]

Works beautifully in x2 mode, but getting nothing with x3 and x4.

My setup:

Panasonic Fz802 (4k OLED)
PAL 50Hz (SNES, Megadrive, Amiga etc)

I’ve tried various settings but never get a picture in x3 or x4 modes. Which is a real shame because the silly TV won’t display x2 mode in 4:3 unless I turn game mode off.

Any pointers would be appreciated!
