Progress update.
Added 2021-11-05 12:14:24 +0000 UTCSeveral fixes to VDP1/2 and SCU. Now there are more runnable games. The VDP2 does not yet support all graphics modes for Rotation Scroll Screen, so there are some missing graphics in the background.
The next task is to achieve the original DMA speed for B-Bus (VDP1 and VDP2).

2021-11-10 15:57:18 +0000 UTCAt this point I can't say definitively. I continue to research the Saturn hardware with a logic analyzer. The memory speeds are faster than I expected (especially during DMA). But I hope to eventually be able to implement all of Starun's memory in one SDRAM module and on-board DDR3.
2021-11-08 08:56:38 +0000 UTCHi Sergey ! Thank you so much for your commitment ! :-) May I ask you, regarding this additional SDRAM module : do you think it'll be eventually required (in the long run) for MiSTer user to upgrade to a dual-SDRAM module in order to get all cores work optimally ? Or is it just something you have recourse to temporarily in order to ease the development process ? THANK YOU ! :)
2021-11-08 08:39:46 +0000 UTCYou're incredible! Thanks for your hard work and for the update. 🙏

2021-11-08 03:57:56 +0000 UTCSo excited for this, thank you for your hard work!
2021-11-07 17:15:06 +0000 UTCThank you for your efforts Sergey. What you're doing is definitely history in the making in the retro world.

2021-11-07 13:14:41 +0000 UTCI will only try to get rid of the second SDRAM module if the core is 99% operational.
2021-11-05 17:08:01 +0000 UTCWill the second SDRAM module remain needed in the final release and if so will a 32mb module be sufficient?
2021-11-05 16:48:38 +0000 UTCGreat progress! Looks amazing.

2021-11-05 16:03:33 +0000 UTCKeep up the good work, I was recently wondering how everything was progressing so this update today felt like a treat :)
2021-11-05 14:43:01 +0000 UTCAmazing!!! Thanks for your efforts :)

2021-11-05 14:30:52 +0000 UTCToo early for any release and still requires a second sdram module to run.
2021-11-05 14:00:16 +0000 UTCAny plans on releasing a demo build? I'd love to try it out on my MiSTer. Even just sitting at the system menu would satisfy 80% of my nostalgia needs.

2021-11-05 13:09:17 +0000 UTCNow around 80% and there will no longer be a significant change.
2021-11-05 12:58:52 +0000 UTCAmazing!!!!
2021-11-05 12:55:04 +0000 UTCThanks for your efforts! Question: I was curious how much of the FPGA utilization you are currently at? The ps1 progress was tracked around 57% with mister os taken into account.
