Sega Saturn Core in Development

[Armakuni]

I guess the lack of road tilting in Power drift is just due to feature not implemented in the core yet ?

Please can someone test the game Shienryu? It's not reported any problem in github for this game, but I'm having wrong rotated graphics in game what make it unplayable.

I've just tried and have the same behavior as you have. Horizontal scrolling for the ships with UP,DOWN,LEFT,RIGHT on my pad correspond to RIGHT,LEFT,UP,DOWN, the background scrolls vertically however. On my setup (single ram) the game freezes after the continue choice also.

I checked the video on the web of this game and it seems that there is an issue with the scrolling. It needs to be vertical like for the background

Is there a reason why last few updates weren't added to update all?

Probably as they're unstable/test releases.

maybe because they are "unstable"?

The core only works with dual ram modules or with one? I say this because they sell me a mister with sdram 2.9 and knowing it or not

Doesn't need dual RAM.
but the higher the SDRAM version the better compatibility.but it will run on lower versions of RAM.

I am going to receive a mister fpga with a 2.9 module. That's why I asked

Dual ram refers to 2 sticks of ram, not the count of Ram chips on each stick

Which build ID is more current? I can't tell between the two latest, the lowest resolution appears to be the day/date.

No The core does not need an unstable Mister

[metalfacemark]

any suggestions to why im getting this black screen issue on the current cores? Ive tried switching bioses, i get the saturn bios loading up but i cant launch any games.

if you have a 4 chip ram then you are out of luck. 2 chip ram is best. V3.0 and v2.9 give the best compatability

[metalfacemark]

I have 2 chip ram in both my misters - v3.0 it says on them.

I thought I read somewhere that v3.0 ram might even have a slight improvement in compatibility compared to v2.9. Is that not the case?

That is not the case.

Some people have good luck with v2.4/2.5 sdrams. My friend got v2.5 from eBay in 2020 and it's running great like v2.9/3.0 rams. Some people on discord also had good luck like one v2.4 from misterfpga.co.uk in 2019 and v2.5 misteraddons dual ram. My v2.5 misteraddons single ram is not good.

Would anyone here with good v2.4/2.5 ram share where you got your ram?

[TLPD-AVW]

I have a good v2.5 SDRAM board from misterfpga.co.uk, ordered in 2020.

[pomegran]

I bought my v2.4, 2 chip 128mb memory from eBay in October 2019 and music still constantly drops out. I haven't tried the latest version released yesterday but I feel I'll be buying a new version of the memory any day soon.

[rhester72]

@pomegran That would be the fix, yes.

[jordi]

I do have perfect experience with 2.5, except in Sega rally, which frequently loses audio parts. Fx, engine, music

But I guess it's a matter of a more stable core
