Re: Mister SNES port to MIST possible?
What custom chips support this port? DSP only?

Yes. The FPGA is 100% full. Even the RGB->YPbPr module didn't fitvebxenon wrote:What custom chips support this port? DSP only?

Sorcery! It works fine with RGB to my PVM.
NeoGeo next?

Re: Mister SNES port to MIST possible?
Amazing. I never thought this would happen. NTSC had a blur running horizontally across the screen for some reason. Super Mario RPG wouldn't load in any rom setting. Super Metroid seems to have corrupted the rom image causing graphical blocks when saving the game which does not actually save through power cycles.
Re: Mister SNES port to MIST possible?
Wow! That's awesome!

Super Mario RPG uses a custom chip, SA1 which is not supported. DSPx chips are supportedTelevicious wrote:Amazing. I never thought this would happen.

Unbelievable. But working. I would say: "IT'S ALIVE!" https://www.youtube.com/watch?v=QuoKNZjr8_Uslingshot wrote:Well guys, maybe MiST is old. MiST is outdated. MiST is obsolete. Already a retro device. And there are very few developers.
...but still good to play some Super Mario Kart:

Many many thanks for this awesome work!
On the other side of the screen, it all looks so easy.
Re: Mister SNES port to MIST possible?
I'm doing some tests: Pac Attack and Cosmo Gang de Puzzle are show scrambled even changing the ROM Type or doing a reset. Just for your information

Re: Mister SNES port to MIST possible?
That's incredible
Many thanks Slingshot for this new snes core for the MiST board !

but something looks strange:
info (170195): Router estimated average interconnect usage is 34% of the available device resources
Info (170196): Router estimated peak interconnect usage is 47% of the available device resources in the region that extends from location X32_Y11 to location X42_Y22
When you say 100% in in the fpga or in sram?

Re: Mister SNES port to MIST possible?
Definitely getting graphical corruption the longer I run certain games like Tecmo Super Bowl. Weird since the NES core also seems to have that issue with Tecmo Super Bowl of graphics corruption slowly getting worse. Metal Marines is a mess right from launch.
Lots of other stuff has no issues though. All the Madden games seem to work perfectly, Kirby's Dream Course is 100%, Zelda ran great, Liberty or Death and Genghis Khan 2 are awesome, Wolf 3D even runs, was surprised at that, though Noah's Ark 3D did not. Zombies Ate My Neighbors ran beautifully.
Also noticed X and Y button appear to be switched from default MiST controller config. Solved with custom config.
Super fun playing around with this.

Thank you !!!!

Those are just the connections between LCs, look at the used LCs in the summary report.rampa wrote:

Re: Mister SNES port to MIST possible?
Thanks for your work, this is a fantastic surprise. I just played R-Type III for an hour and it was perfect, as far as I can see. I finally had to edit my controller config, because I never mapped the L and R buttons to my gamepad, no other system used them so far. 

Re: Mister SNES port to MIST possible?
Thank you!!! 

Re: Mister SNES port to MIST possible?
Thank you!!!
This is great, it is certainly worth publishing on the MiST binaries repo so more people can find it!
Well done.

Re: Mister SNES port to MIST possible?
Pilotwings NTSC also has issues, works until the actual flight mode, then the screen just goes black. Pretty weird considering all the other mode 7 games work perfectly.vebxenon wrote:Okslingshot wrote:Yes. The FPGA is 100% full.

. Well I've done a lot of tests... Pilotwings PAL doesn't work well, I don't know why
. About PAL and NTSC, in my monitor, NTSC signal doesn't work well, it's every few seconds blinking and putting "VGA input". When I play a PAL game, I only get this "VGA input" notice when I load the rom, then I can play without any problem.
Ultraman has background graphic corruption around the edges of the screen for some reason. Top Gear 2 the sound levels were peaking above their limit.
Dunno if anything can be done about all these quirks considering how full the LE's are, but figured I'd report that.
Re: Mister SNES port to MIST possible?
Pilotwings is just about wrong DSP1 detection. I don't see the reason why Pac Attack and Metal Marines have corrupted tiles. Is there any game where the backup RAM feature is easily testable?

About backup RAM you can test Donkey Kong Country gamesslingshot wrote:Pilotwings is just about wrong DSP1 detection. I don't see the reason why Pac Attack and Metal Marines have corrupted tiles. Is there any game where the backup RAM feature is easily testable?

Re: Mister SNES port to MIST possible?
How did you manage to get that to route? With Xilinx FPGA's I'm lucky if I can get 70% full and still route.Total logic elements 24,429 / 24,624 ( 99 % )
Total combinational functions 24,150 / 24,624 ( 98 % )
Re: Mister SNES port to MIST possible?
No idea, it just works with Quartus - usually the timings gets worse if you fill the FPGA fully, but 95% of the core runs just @~21MHz.
