Games with Issues

Today i tried World Heroes 2 Jet and it randomly reboot .
My multi mvs is on the latest firmware and menu, an i use a mv2f with stock bios
 
I had a chance to try Samurai Shodown 3 on a different MV1C, this time with Unibios 4.0. It crashed after about 10 minutes but spit up an error message which you can see in the attached image. Not sure if that helps track down the bug. The cart was firmly inserted and plays other games with no crashes, so it’s not a bad connection.

both errors show ssp=109456 (ssp is a7) which is weird since that's in RAM. Not sure if that helps @Darksoft but that's the similarity between those screenshots. Inspecting it in MAME, that address space seems to be used when sprites are in the air, maybe flight calculation or something. I thought maybe the program code in the multipack was corrupt but it checked out with mame.

I'm pretty confident that this is coming of the UNIBIOS that it's taking too many cycles before returning and then collapes with the routine of the cart to capture going back to the menu or changing slot. Can you try with a stock BIOS?

It seems to be the same behavior that I had reported last year (a few posts back) on my MV1C with stock Japan BIOS, only that one doesn’t put out an error message, just crashes a few fights into the game.

Also with SS3?

Yes. The two games that I’ve found crash in a similar fashion are SS3 and World Heroes 2 on MV1C with stock Japan BIOS. I only tested SS3 on the UniBIOS console, but can check if WH2 does the same. I did test original MVS carts of those two titles and they do not crash (on the stock MV1C).
 
Another year has passed and I still haven’t received any reply regarding the World Heroes 2 issue.
One new thing I’ve noticed is that when I’m logged into the forum, browsing becomes extremely slow, pretty much unusable , while logging out immediately resolves the problem.
This behavior reminds me of measures I used to apply to problematic users on a forum I ran. @Darksoft any hint? Do you want me to leave?
 
I’ve never used a VPN, yet I ran into this “issue” (which, as it turns out, isn’t an issue at all but a deliberately designed feature charmingly called “User Discouragement” in Xenforo) across multiple PCs, browsers, and platforms. Everything was a great experience… right up until I logged in. Now everything works perfectly, thank you for releasing me. Here’s hoping that one day World Heroes 2 will decide to run properly as well.
 
I really don't get it...what tone? I've only replied to this thread for 3 maybe 4 years each year asking for an update and I haven't received any reply. There are at least other 3 guys with my the same problem here so maybe there is a problem. If you don't have the time to investigate just say it, not a big deal...
I’m just stuck on the fact that, 4 years ago, you wrote that you would release a new firmware to fix this issue. And what should I say, then, having purchased the cartridge in 2021? Was 2021 perhaps the last year it could be bought, given that they later sold out?
 
I'll try posting here. I'm looking for some help from owners confirming or clearing these before mentioning elsewhere.

Below are the four games known to have glitchy graphics when played on a NeoSD cartridge. I was wondering if anyone can confirm whether the DarkSoft cartridge has the same issues or a fix for these.

3 games that use 'slow rom' according to the MAME documentation:
Ninja Commando (intro and in-game sprites get swapped out for one frame)
The King of Fighters '94 (there's now a fan patch that fixes the problem)
Ninja Combat (in theory this game should have glitchy graphics too, but I've yet to see any issue with this game myself)

Super Sidekicks 2 (only when 'in-game trigger' is enabled on NeoSD)

World Heroes - Just discovered this one, and I'm not sure why there's an issue. I've confirmed the problem with both the NeoSD Pro MVS and NeoSD Pro AES. The problem doesn't occur with real carts. If you watch the floor, you'll see the sprites move out of place momentarily at regular intervals. Please see the video capture below:
