Super Mario Kart on neo snes myth don't work !
« on: May 28, 2013, 04:20:47 AM »
Hi ! (and sorry for my bad english...).


I have original super mario kart (E) plug on the Neo cartridge and i try to play at super mario kart (U), but the game stay on black screen with "Nintendo title".  ~sm-86.gif~.gif

If anyone can explain to me why roms of super mario kart( Eur,Jap or US) don't work ?

The option menu is on High rom so i don't understand.

I read in the test somewhere in the forum, the game(EUR/USA/JAP) work with original cartridge on NEO Myth.

My original in pal of course work ! but i prefer in US for the 60hz.

Thanks.

I'm guessing that you're using a Neo3-SD and are trying to load the game from SD(?).

It's possible that I never added DSP-1 support (necessary for Mario Kart, Pilotwings and some other games) when loading from SD cards, since I don't own any DSP-1 carts to test with. Perhaps I can check if I could pick up a cheap cart at some auction site in order to get this feature working in case it's broken.

Hi & thanks for your answer !  ;)

Yes you right i talk about NEO3 SD. Why is not the same functionality cartridge of NEO2 ?

I see this post from    kuroiso:
http://www.neoflash.com/forum/index.php/topic,6031.msg44459.html#msg44459

It says, the neo myth snes run :
DSP-1 chip games tested With Super Mario Kart:

-Bike Daisuki! Hashiriya Tamashii (Japan) - Perfect
-Final Stretch (Japan) - Perfect
-Lock On (USA) - Perfect
-Michael Andretti's IndyCar Challenge (Japan) - Perfect
-Pilotwings (Europe) - Perfect
-Super Air Diver (Europe) - Perfect
-Super Air Diver 2 (Japan) - Perfect
-Super 3D Baseball (Japan) - Perfect
-Super Bases Loaded II (USA) - Perfect
-Super F1 Circus Gaiden (Japan) - Perfect
-Suzuka 8 Hours (Japan) - Perfect
-Super Mario Kart (Europe) - Perfect

-DSP-1A: Ace o Nerae! (Japan) - Perfect
-DSP-1B: Ballz 3D (USA) - Perfect
-DSP-2: Dungeon Master (Europe) - Perfect

So my question is :
What is the firmware version ?
& What is the menu version ?
(old menu version is v0.05 and firmware ?? xxx.01)

Do i must downgrade ? can i ?

Because with menu version 0.58 Super Mario kart (E) don't work ! at all ! except if i run the cartridge !
So if Super mario kart (E) run , i think the US version can work too...

It's my opinion.

Thank you and i hope the neo team work on next upgrade with this option !  ~sm-43.gif~

The difference is whether the game is loaded from SD vs loaded from the game flash memory that was present on older (Neo2) carts.

The original menu from neoflash could only load games from game flash, and it handled DSP-1 games.

The newer menu versions which handle SD card loading are written by me, and they don't use the same code for loading the games since reading from an SD card is very different compared to reading from the internal game flash. I never tested whether DSP-1 games would load correctly from SD since I didn't have any DSP-1 carts to test with at the time.
I'll see if I can fix this in the near future.
