Dual SDRAM Update All Script?

[PC_Denjin]

Hello all,

As I am a total noob when it comes to compiling the cores on my own (or similar things in general), I would like to ask whether there‘s a update all script available specifically for dual SDRAM setups?

Just recently updated my mister with dual RAM, but I am having a hard time finding the most recent compiled core for Saturn. Even on the discord channel it seems like dual ram Saturn core is not there (or I need new glasses which could also be the case to be honest ).

Does the PSX core still get any benefit from dual RAM modules? Or any other core for that matter?

It gets a measurable but completely imperceptible marginal accuracy boost to sound timing.

I see. I assume there is just one RBF file and the core can detect and leverage the extra RAM stick if present? I had an old 32mb module laying around that I added to my setup for grins and just wanted to make sure I didn't need any alternate versions of cores.

No there are no Dual ram/ Single ram cores
you have to download either the Dual or Single ram version.

Gotcha. I checked on GitHub and all I see is the normal single RAM RBF. Is there a way to get ahold of a pre-compiled version of the dual RAM core?

I get it from Discord. There isnt a PSX dual core build thats officially created. The difference doesnt make it worthwhile other than to test you have dual ram set up correctly

Nate did an excellent tutorial on dual ram HW setup

srg320 was asked directly about this yesterday (28/11/23) via a Patreon message shared with me over claims made in this thread and the other Saturn core thread about the GitHub requirement of dual SDRAM being outdated / inaccurate.

srg320 has confirmed the information posted on the Saturn core's GitHub page with regards to dual SDRAM is correct and accurate.

Is there still a separate build for the dual SDRAM setup or can the existing core determine if two RAM modules are present and make use of both of them?

[FPGA64]

Saturn has 2 builds they are both in the Github but you must be logged into github to see them

I created a GitHub account, but I still can only see „Saturn_unstable_20231018_144d28.rbf“ in the unstable_builds folder, which I assume is single RAM.

In Discord I also don‘t see any dual RAM files, there‘s only the single RAM version as above in the unstable builds channel.

Is there a guide for dummies explaining how to use the files from GitHub to compile it?

Here is a YouTube video that walks through compiling the PSX core for dual RAM. I'm assuming the procedure for the Saturn core would be similar. I haven't tried this yet, so can't really speak to how easy it is though.

Thanks for the information everyone!
Fortunately the latest Saturn dual ram file is on discord now, yaaaaay (guess I would never have managed to compile it on my own, even with a YouTube video ).

Did you find one from October 18th? The newest one I could see on the Test Builds Discord server was from September 19th.

[PC_Denjin]

Yes, the latest one on discord in the unstable-nightlies channel is from November 30th.

The link I gave is the official build artefacts for the Saturn. Its triggered when SRG makes a commit

[MiSTer Consoles]

I found the correct server/channel. I had been looking at the MiSTer channels under the FPGaming server previously. Thanks all!
