Is NetLink support possible?

Ask a question about the Sega Saturn Compatible FPGA Core

Hello! I was curious, is it possible that one day we could see NetLink support added to the MISTer Saturn core? NetPlay is back and working for users on actual hardware: https://www.segasaturnshiro.com/saturn-community-projects/online-play/
So I was thinking it might be fascinating to see if a device like the MISTer could make that experience easier (and less hardware dependent with extra adapters and a dreampi).

Black screen on monitor whenever there is a scene change in die hard arcade

Version (or build number)

20240323

Single or Dual SDRAM?

Single (128MB)

Steps to reproduce

Run and play die hard arcade on a pc monitor. The screen turned black for about 5 seconds whenever there is a scene change and the game is still running in the background regardless. Quick time event thus occurred when screen turned black, unable to see a single thing failing the mini game every single time as a result.

Expected Behavior

Screen should quickly resume whenever there is a scene change and not stuck on a black screen for 5 seconds.

Actual Behavior

The screen turned black for about 5 seconds whenever there is a scene change and the game is still running in the background regardless. Quick time event thus occurred when screen turned black, unable to see a single thing failing the mini game every single time as a result.

Core doesn't build due to inconsistent debug ifdef

There's some assignments that are made on ports that are conditionally created on debug ifdef (suggest building without debug defined to confirm). I'm building on quartus 17.1 on linux. Thanks for your hard work :)

Akumajou Dracula X - Gekka no Yasoukyoku (English v1.021) hang after defeating Succubus

Version (or build number)

20231018

Single or Dual SDRAM?

Single (128MB)

Steps to reproduce

1. load savegame from the .zip to /media/fat/saves/Saturn Akumajou Dracula X - Gekka no Yasoukyoku (English v1.021).zip
2. load Akumajou Dracula X - Gekka no Yasoukyoku (English v1.021)
3. start the game, and load the save game with 102.6% of the game, starting in the room at the right of the save game room:
   
4. enter into the pink false savegame, starting the "Nightmare" screen, and defeat the enemy ("Succubus").

Expected Behavior

It should work like in the following YouTube video, i.e. exit the scene after defeating Succubus: https://www.youtube.com/watch?v=BisuaEUlqOk

Actual Behavior

After Succubus being defeated, the music ends, and there's movement, but it gets stuck. It happens both if pressing start or A for speeding-up the scene, and also waiting until it finishes by itself. See mp4 video I've just made it, it is a short video, but it is like that, but in an infinite loop. The video works, but the audio stops. Just in case for you it means something

sotn_saturn_hang.mp4

Update 1: it behaves the same having the holy water secondary weapon instead of the clock.
Update 2: it behaves the same disabling (debug): SSCP {Direct|DSP} sound / CD audio

Screen Horizontal Alignment Issue on CRT via VGA RGB

Version (or build number)

f05dd39

Single or Dual SDRAM?

Single (128MB)

Steps to reproduce

1. Use the following settings in Mister.ini:
2. vga_mode=rgb ; supported modes: rgb, ypbpr, svideo, cvbs. rgb is default.
   ntsc_mode=0 ; Only for S-Video and CVBS vga_mode. 0 - normal NTSC, 1 - PAL-60, 2 - PAL-M.
   composite_sync=1 ; set to 1 for composite sync on HSync signal of VGA output.
3. Use the following Saturn bios files: Sega Saturn 1.01 Japan
   Sega Saturn 1.01a USA
4. Connect Mister using VGA to RGB BNC cable.
5. Start up any game with the correct region and BIOS selected
6. BIOS screen and game screens are horizontally misaligned on the screen. The screen is moved over to the left, which cuts off part of the game and leaves some empty black screen space on the right.

Expected Behavior

BIOS and game screen should be centered on the screen without anything cut off on either side.

Actual Behavior

Screen is off-center to the left which cuts off part of the game and there is a small empty blank black space on the right.

[Radiant Silvergun] Missing Background Textures in Stage 2c

Version (or build number)

20240504

Single or Dual SDRAM?

Single (128MB)

Steps to reproduce

1. Map Joystick
2. Load HiSaturn Bios Ver 1.03
3. Load Radiant Silvergun
4. Load Save Game 1
5. Play the game normally up to Stage 2C.

My Save File:
Radiant Silvergun (Japan).zip

Expected Behavior

Saturn Hardware

(Timestamp 20:03) https://youtu.be/aWIhkS-er6g?si=sXdqukpApMlVgyea&t=1203

(Timestamp 21:10) https://youtu.be/aWIhkS-er6g?si=xbGvxpzy6HMNfqwq&t=1270

Actual Behavior

Missing background textures do not display, as shown in my screenshots above.

I'm not sure if this playthrough is on Mister, but this video has the exact graphical glitch I'm having:
(Timestamp 23:40) https://youtu.be/Wue0F5YyeEQ?si=g0AYRVTXpoJUJAeF&t=1420
(Timestamp 24:48) https://youtu.be/Wue0F5YyeEQ?si=WfGODlSIRv1vsZe3&t=1488

I have not beaten the game yet so I do not have level select unlocked. But my save file is nearly max level, in case it helps reach Stage 2C quicker.

On the topic of max level weapons, I have never played this game on original hardware but noticed that the high level Homing Spread (Button X on Saturn pad) lags the game quite a bit for later bosses and stages (when there's lots of targets to lock onto, like the bosses NASU or DAN-564, or Stage 4B). I don't know how much the game lags on original hardware but I figured I would bring it up just in case.

Single (128MB)

Steps to reproduce

In attract mode of Virtual On (USA), for some reason, the demo ALWAYS defaults to the exact same virtualoids and arena on every loop, while on original hardware, it always will play a different, random set of virtualiods and arenas.

Expected Behavior

Every time the attact mode loads a demo fight, it should be a random selection of virtualoids and arena.

Actual Behavior

The attract mode ALWAYS defaults to the exact same virtualoids and arena on every loop

Rotate screen for TATE CRT users

Ask a question about the Sega Saturn Compatible FPGA Core

Hi, great core i love it. Is there any plans to add an option to rotate the screen? This would be for TATE (vertical) users using CRTs, often in arcade machines where flipping the screen isn't so easy. The PSX core currently has this option.

There are a limited number of games that support TATE on saturn (about 22, listed below):
Galactic Attack
Up'n Down, Pengo and Head On (Sega Ages: Volume 1)
Gun Frontier
Gun.Smoke, Mercs and Commando (Capcom Generations IV: Blazing Guns)
Kyukyoku Tigers 2 Plus
DoDonPachi
Batsugun
The Game Paradise!
Battle Garegga
Gunbird
Sonic Wings Special
Strikers 1945
Shienryu
Strikers 1945 II
DonPachi
Gekirindan
CrimeWave (hold L+Y and press Z)
1942, 1943 and 1943 Kai (Capcom Generations I: Wings of Destiny)
Kingdom Grandprix
Zippy Race (Irem Arcade Classics)
Vulgus and Exed Exes (Capcom Generations III: The First Generation)
Image Fight
Skull Fang

It would be a great feature, but totally understand that it's probably low priority given the smaller userbase running saturn for TATE games :)

Rams with 4 chips

hi @srg320 , i read the readme, where is specified that the first ram should have 2 chips.
I assume you are doing something special with the 2 chip configuration, and i have a setup with 128megs on 4 chips, and i wonder if that can be an issue.

Do you know anything about that?

thanks for the fantastic work!

Steps to reproduce

1. Start a game with that uses an interlace video mode (Dead or Alive, Burning Rangers menu)
2. On a real CRT, observe visible combing artifacts that are not observed from a real Saturn

Expected Behavior

Not seeing combing artifacts like on real hardware. This is hard to show an example of because it's hard to record a CRT.

Actual Behavior

Switching between a real Saturn and MiSTer, the combing artifacts are visible on the CRT. Both my Saturn and MiSTer are outputting RGB that is converted to YPbPr with a RGB2COMP.

Albert Odyssey - Unreliable saving, losing data

Version (or build number)

231018

Single or Dual SDRAM?

Single (128MB)

Steps to reproduce

Play Game
Save Data at Save Point In-Game
Open OSD
Save Backup RAM
Reboot MiSTer
Load Save Data In-Game

Expected Behavior

Reliable saving

Actual Behavior

When playing Albert Odyssey using the v1.00 USA BIOS, I'll open the OSD and select Save Backup RAM. After a reboot of the MiSTer, sometimes it will have saved, sometimes not. I've tried rotating through multiple saves spots, overwriting, etc and it seems to happen without a pattern. Most of the time it didn't save correctly. The date/time is also incorrect as the BIOS settings aren't saved when loading a disc.
