Achieving the best picture using Bettle PSX at 240p

[alphanu]

What hardware and OS are you running, have you tried the DYNAMIC option yet?

I'm using my main computer, with Windows 10 and two different GPUs: Radeon 5450 and a Nvdia GTX 1080.

For 240p gaming I'm using the Radeon, and since I'm using two different displays I need to make my CRT the primary monitor when I want to use Retroarch.

I'm trying to learn more about MME4CRT before using it. Right now I'm just using native resolutions manually, but sometimes not exactly native.

When playing SNES games, for example, I prefer to use 296x240 (or 304x240) instead of 256x240 because I think SNES games looks nicer with square pixels. The native SNES resolution (256x240) looks too stretched for my taste. Same thing for GBA and others systems with a horizontal resolution lower than 320.

So, I need to pick resolutions manually because some are not exactly native. I guess MME4CRT would not help me with that, unfortunately. 

I'm still not sure how Dynamic would work, to be honest. If I'm playing, for example, a game with a native resolution of 384x224 - the calculator says the dynamic resolution will be 1152. Do I need to have to have a modeline of exactly 1152x240 installed on the video card drivers before using it?

For Snes you should really use 512x224@60 Snes should be 224p for NTSC and 240p for PAL. As a few games use this resolution. Bsnes uses 512 by default.

Yes, calculate the horzontal and use that. So, you should end up with 1152x224@60 or 50.

I am going to release a debug version soon. T will give you the actual resolutions being requested.

For 240p gaming I'm using the Radeon, and since I'm using two different displays I need to make my CRT the primary monitor when I want to use Retroarch.

This is being worked on. So, eventually you will not need to set the monitor to primary.
