I just wanna say I can't get the sound of that butterscotch candy out of my head.

Why, just why!

Loading larger sets of files improved in FW 0.8.3 and an option to turn on/off the navigation sound in menu.

Have you gotten far on the homebrew/hack/port stuff? I haven't had time to mess with it for a handful of days now but I was running into trouble on several of them, getting Illegal Instruction errors or other crashes. I cleaned the 1 slot I'm using again, I don't think it can be a connection issue even though I know that's the most common cause of the green screen.

So far, just TEOT due to the known issues with Darksoft cart and Double Dragon One.

The new grouping option should make it easier to test those out.

Thanks, I don't think I've tried the DD One demo, I'll see about updating the firmware and try it tonight if I get a few minutes. Out of curiosity are you using MAME romsets or Darksoft run through the decoder or is it some of both?

What’s the issue with Double Dragon One demo and the Darksoft cart? I’m a beta tester on their firmware and this is the first I’ve heard of any problems. Nothing has been mentioned on the AP forums that I’m finding.

None, it was TEOT. I only mentioned DDone because it was the other hack/homebrew/demo I had tried

Well I tried a couple of the 8 and up firmwares but was having issues so I formatted the card and loaded 7.9

Not sure if it was the reformat or the FW rollback but I had tons of luck on stuff I hadn't previously so I'll probably leave it alone for now.

I had Cyborg Force, Captain Barrel, Neo Pang, Neo no Panepon, Last Hope, 19YY, and Shinobi running for a while.

Double Dragon One and GladMort demos seemed to work too

Neo Super Mario Bros worked for a couple levels before I got an illegal instructions error.

Golden Axe played a little while on the first stage before getting a crash as well.

I'll test a little more later tonight.

There's a glitch in the NeoSD that causes Karnov's Revenge to get the GSOD after booting the game and letting it run to the splash screen and then running a demonstration after a couple of minutes.

Can anyone confirm if it happens with this cart and Darksofts?

Heads up that @evietron added the patch to the decrypt tool for Samurai Showdown V Special.
- before this update, SSVS would have a pop when announcer said 'Basara' in character select

We still have to manually apply the patch to the perfect ROM as it's not decrypted by the tool.

I also ran the game for a few minutes allowing it to cycle through the intro, title screen, game demonstration 3 times with no crash.

Here is my experience so far with a bunch of homebrews, hacks, and ports. I'm sure some of the issues are still something on my end and not anything that necessarily needs fixing but I just wanted to share and see how anyone else is coming along on non-official titles.

Testing was limited to a few minutes if it was working so this is not fully checked but just a starting point.

This is using firmware 0.7.9 on Backbit cart running on an MV-1A with Unibios 4.0

Spoiler:
19YY - plays through, has sound, resets to menu
Abyssal Infants - plays through, has sound, won't reset to menu

No problems with Karnov’s Revenge on the Darksoft cart with the latest firmware.

I ran it for a while on my NeoSD Pro MVS with Unibios 4.0 in USA MVS mode. I didn't run into any issues letting it run attract mode for a while.

Any reason why everyone's referring to it as Karnov's Revenge now instead of Fighters History Dynamite?

There's 4 games in the Fighters History Dynamite series. Karnov's Revenge is basically Fighters History Dynamite 2.

Cart is up and running. Only tried a few games so far: NeoTurf, MagLord, Windjammers, MetalSlug 1&2, Garou, all work great through the Furrtek, no issues. Metal Slug X, however, I cannot get to load. It just glitches and infinitely loops through the load screen. Might be Furrtek-specific, not sure, Haven't pulled an MVS out of the closet yet to try direct.

Update: tried on MVS, still can't load Metal Slug X, but instead of an infinite boot loop, it just boots to a completely black screen.

Do any of these flashcarts work better than using the Mister ROM set? Serious question, not trolling.
