Vamos, a ver. ¿Es seguro que la SDRAM de 4 chips hace incompatibilidades con el core de Saturn, o simplemente ha habido una coincidencia y todo el mundo lo achaca a eso?
Como ya comenté hace 8 meses, la explicación podría ser otra.
En el foro de Mister FPGA han comentado estas cosas:

Today I updated the newest core and unfortunately there are still problems with many games on SdRam v3.0. This Ram is an absolute failure. I advise against anyone buying this crap!

I can't boot any game with the Antonio Villena's SDRAM.
I have the same problem as well! :shock:
If you get this resolved please let me know!!
Funny enough I had more game booting
with the previews version of the core running on Antonio' Mister and sdram.
With this one most games don't boot.
But again it's pre alpha alpha alpha stuff. So you can either wait for the core to be in a betaish state to see how it goes, or just buy new ram now.
In my case, I'm just gonna wait.

I hate to have been "prophetic" at an unsuspected time, but here we are; sticking to the official specs of the project, at least as far as the main hardware components are concerned, will keep you on the safe side regarding future developments based on the given MiSTer platform.
Since no other core have problems with Antonio's ram (PSX included) I don't think it's fair to say that just yet. The current Saturn core is in such early state that every variation in design counts, but I don't expect the final core to have any issue. I also want to mention, that a core like
the Ao486 is actually more stable at over 100mhz with Antonio's setup (mine anyway) than my friends Mister which can't use the core at this frequency without regular crashes. He has different ram module and different Mister altogether, so I don't know if that's why, but I just wanted to point this out.

Did you all update the Mister Main also... some folks forgot that part
¿Alguien ha cogido una SDRAM de 2 chips, le ha funcionado el core de Saturn, cambiado por otra de 4 chips, fallado el core con los mismos juegos, y vuelto a cambiar a otra de 2 chips y volver a funcionar?
Pregunto, no tengo ni idea de si se ha hecho, pero eso si sería una comprobación adecuada para relacionar las SDRAM de 4 chips con los problemas.
Aunque sigo sin entender como puede ser que una memoria de 4 chips pase todos los test de SDRAM y luego falle con un core concreto.
