Sega Saturn Core in Development

[djsquare]

New update from SRG320 today, anybody tried it yet? It does not even start on my MiSTer

I doesn't work for me either but I haven't tried the dual RAM version yet on my other MiSTer

[rhester72]

Dual RAM version also just black-screens and hangs, not even possible to open the menu

[djsquare]

I'm wondering if this requires a new unstable main file

PSA: This build looks for boot.bin, not boot.rom! Rename your boot.rom to boot.bin and it will load.

[rhester72]

If you do that, you get "CD BIOS not found!"

[djsquare]

Alright, I got it working
1) do what mikeboss said
2) then select that same bios in the core menu
3) Play Albert Odyssey

[mikeboss]

nice, Tempest 2000 finally works!

[Nickie]

black screen regardless if boot.bin , or boot.rom

thinking it requires a newer unstable MiSTer ?

It stays with a black screen, but you can enter the menu now and fumble your way to get something to load.

Sometime you need to reset from the menu (for EU und JP for me), some Bios start straight up (US).
Then you can load your cue and hope for the best

it works for me with the latest stable. most times it doesn't work right from the start. I had to reset the core, reload the game, reset the core etc. but it worked in the end...

Anyone has link for the new built?

nope i can't , i see that resolution changes but menu doesn't appear from controller shortcut, or directly from mister button

[EDIT] updating Mister to latest unstable did nothing, saturn core from june 8th runs, latest one doesn't, i have both boot.rom AND boot.bin in the folder , and nothing , very puzzled

[rhester72]

Delete boot.rom. Do EXACTLY what djsquare said. Load the core, set the region, load boot.bin from inside the core, load your game, in that order. It will throw an error that the CD BIOS is missing, then will work anyway.

[Nickie]

Delete boot.rom.

ah i found that there's a boot.rom in the GAMES folder too , i had seen one in a BIOS/Saturn folder for some reason and just touched that one!

obviously i put the one in the Games folder but that was a long time ago so i forgot, i even kinda assume that the other one is not even used nowadays even ? deleted it and everything still works!

Very happy with the latest build. I am seeing more games booting and also more games advancing further to playability. Would be nice to auto switch the bios and region depending on the ISO sometime in future as I think this may be causing some compatibility issues for some. The main thing is that Sergey is safe and well of course.

Black screen for me, i think it's the SDRAM...

Where did you download this build?

[MrSniffles]

Black screen here too - totally locks up my Mister. Can't bring up any menus.

[neogeo81]

you must rename the boot.rom to boot.bin. you will get a black screen, you then can open the OSD and load the BIOS and after that the game itself.

Sorted, thank you. I had copied boot.rom to boot.bin, just to be safe (so both exited). Turns out not that safe at all

[srg320]

1. Try last build 20230702.

2. The cd_bios.rom must be located in the directory with the game image or one directory above.
   For example:
   /Saturn/US/Alien Trilogy (USA)/cd_bios.rom
   /Saturn/US/cd_bios.rom
   /Saturn/JP/Batsugun (Japan)/cd_bios.rom
   /Saturn/JP/cd_bios.rom

3. Or the boot.rom must be located in the "core" directory.
   For example:
   /Saturn/boot.rom.

4. Or you can select any bios file (*.bin) manually using the menu.

[neogeo81]

Thanks. So the boot.rom boot.bin situation is solved with the latest?

[Alkadian]

Did somebody manage to run Radiant Silvergun with a single sdram setup?
Thanks!

[breiztiger]

Black screen for me on radiant silvergun

Stull locked out black screen if using boot.rom.
Changes back to boot.bin. works great again.

Works but has massive glitchy sound.

Thanks. That's interesting. Perhaps a different rom? I just get a blank screen same as the user breiztiger.

With previous releases of the Saturn core the game was booting but was crashing after a few seconds.

Pretty much the same for me.
