Pac-Man has this issue on the NGP core too. Wasn't it listed as working early on? The game has a flashing Namco logo at startup. Could that be causing issues?

'Samurai Shodown! - Pocket Fighting Series' on the NGP(/C) cores. The game isn't responding to controls anymore on version jtngpc_20240831.

As I don't see it on the current list and this need a special note after my tests.

• Some games like 'Metal Slug - 1st Mission' were redumped cleanly some time ago, without any save file attached to the ROM file. That newer clean dump doesn't load on the current NGPC core anymore (jtngpc_20240831).

• The controls on 'The Last Blade' aren't responding anymore with the clean saved file too, but the game was playable with that version under jtngpc_20240818 (MiSTer).

After some more tests and the video from PixelCherryNinja, it seems to be that the current up-to-date NGPC set (with save cleaned flash chip) isn't working as intended on the core as of now, but games were working on a previous beta version. And we must use an older set with save inits already present on the dumped flash chips.

You must use the older dump which contains already save init from 0x1E0000 to 0x1E00FF. If you want these games to work on the core at the moment.

So something to check with the core source code.

Thanks to PixelCherryNinja during his video & confirming these games are working under that conditioon.

Would like to add that Sonic Pocket Adventure is not saving. It's playable, but it isn't able to save. Verified by restarting the core. Also note that by editing the game ROM to run in debug mode (edit 0x1F as FF), it refuses to save, but is more prominent with error messages. In an emulator, it does not do that.

Revision for 09e08c610d01334021bda96d6365fc6d2f7b74a4

• I'm adding to the list Neo Dragon's Wild. It starts but it collapses on the start screen and is unplayable

• Ogre Battle Gaiden, Last Blade and KoF Battle de Paradise seem to be working

• Kikou Seiki Unitron starts and lets you play, but some graphics are broken. For example, the borders of the chatboxes or this map:

But most of the other graphics seem to be fine in this game

• Interestingly, KoF R-2 is playable in JTNGP but not in JTNGPC
• Some of the games that show a blank screen send the core to a power-off-like state where you can just load another cartridge. Similar to when you press the coin button to "turn it off" before changing the game, skipping the starting settings, but after the blank screen the settings are not saved anymore and they have to be input again. For example, KoF R-2
• Other blank screens seem to collapse the core completely (Pac-Man) preventing you from turning it off or loading another cartridge

[Zet-sensei]

I could add some issues :

• Neo Turf Masters, Last Battle & Samurai Shodown 2 Pocket: A 1px vertical line flashes during screen transitions;
• Samurai Shodown 2 Pocket : Flashing line just above the POW bar;
• Sonic the Hedgehog: When you complete a level, the TIME BONUS message in motion has a missing line while moving (the first line is already permanently displayed on screen).
• Densha de Go 2: Flickering black bar on the bottom side of the screen when the announcer voice can be heard.

EDIT : Can't reproduce the last issue seen some moments ago, so I already removed it.

SNK Gals' Fighters still boots to a blank screen, even after the Halloween update.
