Whatever happened to The biggest batch so far (Part 2)? Is there more Tamori no Picross in our future?

I recently got a DD, as well as Mario Artist: Paint Studio and Sim City. Until now, both disks worked. However, Mario has suddenly stopped reading, I get error 23 every time. Sim City still works. There looks to be a handful of very tiny marks on the disk, like fluff, and a faint ring that follows some of the disk's circumference. On the advice of the seller I gently cleaned the disk with a cotton bud and isopropyl, but still no luck, so they recommended I reach out here. Any help would be mega appreciated!

Whenever I try to rip the mario artist talent studio ports sound bank with soundtool, sound tool crashes, any idea why? got soundtool here https://github.com/jombo23/N64-Tools
and the ports here https://64dd.org/dumps_p.html

I just got back from Japan and have friends all over the place over there. on the flight home I ran into a article talking about a fan made f-zero2 copy of the game based of found footage and thought it might be cool to hunt these things down with a friend(these things being games that have not been backed up yet). How should we vet these things out and verify what game is on the memory card and if it works at all? his first search came up with 3 of them at 6800 yen. would send the pic but...

Your retrospring isn’t being linked on your current website, are you not really wanting to ask questions anymore?

The Mario Artist Talent Studio cartridge port corrupted seemingly without warning on ED64P, the save data won't open in-game nor in MFS Manager (great program by the way), is my save completely nuked? (I've been keeping periodic backups in case this would happen thankfully, only ~2 Talents were lost and I have reference photos for future recreation)
...I guess this is a good time to ask, how in-depth is the SummerCart64's 64DD emulation? Does it allow for disk swapping? And does it save 64DD games quickly?

What do you think would be the easiest/cleanest way to enable Capture Pak/Cassette support for the Mario Artist cartridge ports (if there weren't any restrictions on budgets and motherboard availability)?
A GameShark-like cartridge stack? Hacking the Capture Pak support to recognize it from the bottom port and sticking a device there? Somehow getting something like the Doctor V64 to work and save correctly with the cartridge ports?

Can I play The Town Whose Name Was Stolen on an emulator? I mean, properly playing it. Is there anything to do, or is it just an empty town?

(Sorry for contacting you again on RetroSpring, I don't know if you're still active on Reddit and I don't have Twitter) Every release of Altra64 hosted on the repository by Suprapote claims 64DD games don't save, is this the correct version of Altra64 for 64DD saving?
The menu version I'm currently using is already some sort of flavor of Alt(ra?)64 (I'm not entirely sure which), it at least boots 64DD cartridge ports

Which savetype do I need to set the Mario Artist games to for them to save on the ED64P? SRAM 32 and SRAM 128 don't work (I'm resetting after I'm finished playing, so that's not the problem)

Hate to ask again regarding the Mario artist polygon studio soundfont, but is it possible to rip its sounds?

how much text is in Marvelous? I’ve never played the game, but I’m a translator who hasn’t done much in ages, and if it’s relatively light, I might be able to offer help?

Have you played Return to Monkey Island?

Are you still working on Marvelous 2.0 and BS Detective Club?

Hi! Do you happen to know if theres an english translation for the GBC version of Hajimari no Mori? Or if anyone is working on one? Tysm if you happen to know!
