Homebrew Saturn emulation using Cotton/Guardian Force testing and debug

[Deleted member 323844]

New test. I will left the xYuunax's optimized ini for worst-case scenarios once I finish with my list.

Panzer Dragoon (US). Playable. No issues so far.
Panzer Dragoon Zwei (US). Playable. No issues so far.
Panzer Dragoon Saga (US). Playable. No issues so far.
PGA Tour Golf 97 (US). Playable. No issues so far.
Princess Crown (JP). Playable. No issues so far.
Radiant Silvergun (US). Playable. No issues so far.
Rayman (US). Unplayable. Running animation does not work (1), so it breaks almost all Rayman moves, including the long jump. I have to try the EU version.
Resident Evil (US). Unplayable. Hangs at the first screen.
The Need for Speed (US). Playable. No issues so far.
Road Rash (US). Playable. Not sure if it runs fullspeed, since I haven't tried the Saturn version before, but it is a bit slower than the Playstation version.
Sega Ages: OutRun (US). Playable. No issues so far.
Sega Rally Championship (US). Playable. Mode selection screen (2) is a bit corrupted and has some slowdowns (this screen). Other than that it works flawlessly.
Sega Touring Car Championship (US). Playable. No issues so far.
Sky Target (US). Playable. Has minor slowdowns when there are tons of effects on screen, could be the game itself, not the emulation,
Scorcher (US). Playable. No issues so far.
Sega Bass Fishing (US). Playable. No issues so far.
NiGHTS into Dreams (US). Playable. Minor blinking line at the left side of the screen (3), barely noticeable. Could be some overscan thingy.
Sonic 3D Blast (US). Playable. No issues so far.

So there will be a native and customizable Saturn emulator on Switch?

@stranno what are the clock speeds for your tests? I'm assuming docked mode as well.

Max CPU overclock (HAC-001) and dock mode, yes. It probably wont require as much, but I'm a bit lazy

Yea majority of the games play fine on stock clocks, but it's a good benchmark to know. I'm strictly using portable mode and slightly overclocking cpu to 1326 on certain titles, maybe 1428 on a few like BR.

Can someone try shinobi legions and x men vs sf maybe I’m doing something , can’t get past the loading screens

for Marvel vs SF, you can try my config, update BusWait=“1”. Performance is not great, I havn't really done much testing with this title yet.

And only copy cotton.bin in the correct path or i must copy all original files of cotton and replace the .Bin?

Just place your .bin rom files in into atmosphere > content > [game ID] and rename the ROM .cue file to Cotton2.cue (if that's the game you're replacing)

Would that be awasome if we could have the saturn boot animation with sounds when we boot up the game? Oh that gives me shivers

For that we must find a way to load a saturn bios, if it's possible.

I don't know if bios even works on this. With the setting `SaturnBIOS="/saturn_bios.bin"`. Drop the bios in the romfs folder, I get no error code and emu continues to load, but if the file is missing I get error code. So I think it sees it, but don't know if it even loads it and just didn't show splash screen? Can't tell to be honest...

So I want to go ahead and share the covers I have. All of these I just simply cropped as they were images designed for CD cases.
They all originate from this thread over on thecoverproject - http://www.thecoverproject.net/forums/index.php?topic=19753.0

The OP of that thread also provided the photoshop templates he used. I'll go ahead and attach them to this post as well.
I have no photoshop skills or anything similar, so if others want to contribute and make more similar to these, using the template, it would be incredibly appreciated as I think these are perfect for what's currently happening with the injections.

Intresting, I'll investigate.

X-men vs street fighter was full speed when I tested it. I changed the memory to 4mb and also OC gpu and cpu.

Hey a heads up on the opening logos.. I didn't change anything but I realized the NSP the script is creating launches directly to the controller image (Do we have a generic replacement one yet btw?) completely eliminating the Success, Zebra Engine, etc logos. Idk if you'd still want to inject the Saturn and Sega logos, but yeah.

So I want to go ahead and share the covers I have. All of these I just simply cropped as they were images designed for CD cases.

i made a template and remade the entire Design from scratch, i can drop an image in Photoshop an shuffle all the style i created
ill share a sample of what i am doing in HD first

and i made an intro logo to replace Success/zebra engine by going directly to PlayerGuide Controller screen and replace it with the new image
ill share the .Tex file later or just rename the pictures and add the header before %PNG and rename to .Tex

if anyone is serious and knows how to compile Cotton2 and removes all cotto2 reference and can compile the new NSP with my Assets send me a PM or join my Discord an i will share more assets

now i go research how to do what i just said, unless someone wanted to share that info with me

 

[drock82828]

Thank you sir

 

[NANASHI89]

Are you guys making custom Saturn injects via NSP? Separate from the official Cotton and Guardian Force NSPs?

Another round of tests.

Sim City 2000 (US). Playable. No issues so far.
Sonic Jam (US). Unplayable. Crashes after the intro and the first screen.
Sonic R (US). Playable. No issues so far.
Soviet Strike (US). Playable. No issues so far.
Spacehulk: Vengeance of the Blood Angels (US). Playable. No issues so far. The Emperor protects, but a guide to understand this thing comes in handy.
Star Fighter (US). Playable. No issues so far.
Street Fighter Alpha 2 (US). Playable. No issues so far.
Street Racer (EU). Unplayable. Black screen right away.
Taito Chase H.Q. + S.C.I. (US). Playable. No issues so far. Only tested Chase H.Q.
Tama - Adventurous blablabla (JP). Unplayable. First logo screen is corrupted and it hangs in the second one, corrupted as well.
Theme Park (US). Playable. No issues so far. Ground tiles look a bit weird sometimes, but I guess it's just part of the quadrilaterals magic.
Thunderstrike 2 (US). Unplayable. Game works, but Z-sorting is all over the place (1). Good lord Core and Crystal Dynamics games.
Tomb Raider (US). Playable. No issues so far. Perfectly working Core Design game, that's something new.
Transport Tycoon (US). Playable. No issues so far. But this port SUCKS, it has worse resolution and performance than the Playstation port and it lacks the 3D mode. Anyway, you can play OpenTTD on Switch, which is the defintive version of the game (tho it lacks the 3D mode of Playstation).
Virtua Cop (US). Playable. No issues so far. But the guy that designed the two inputs for reloading should have been fired right away.
Virtua Cop 2 (US). Playable. No issues so far.
Virtua Fighter (US). Playable. No issues so far.

Super awesome that we can play Saturn on our switch!

I've always wondered why people care about getting the Capcom arcade games running though. FBA plays them perfectly, with a smaller space footprint on your SD card, and no loading between rounds.
