Reason: Compatable, but bad dumps.

Place in Drive 1, leave Drive 2 empty.

This one is quite interesting.

started working on a set. I'm open to anyone wanting to collaborate to make challenge achievements. Already finished most major code notes needed and progress achievements (unless there's some secret hard mode cheat I missed).

sounds like a good gift for christmas next year

nah, pc-88 will still be unofficial only by xmas next year

added rich presence

After analyzing existing dumps, here is my conclusion:
1. TOSEC unlabelled (= Neo Kobe [Set 1]) is corrupted and is missing two sectors. Otherwise it corresponds to TOSEC [a2] (= Neo Kobe [Alt 2]).
2. TOSEC [a] (= Neo Kobe [Alt 1]) is likely a clean rip of one version of the game.
3. Neo Kobe unlabelled (not in TOSEC) is likely a bad dump of TOSEC [a] (= Neo Kobe [Alt 1]), as one sector is empty and the context (content of the surrounding sectors) makes it seems like an error.
4. TOSEC [a2] (= Neo Kobe [Alt 2]) is likely a clean (or at least cleaner) rip of a second version of the game.

As for the differences between those two versions, I assume that the second version mentioned above is a revision of the first. There are some code changes which lead to memory shifting around a bit, so alts are needed to support both. Gameplay-wise, it seems to me that the second version draws screens slightly faster, and it implements double buffering, while the first version draws directly to the screen, and one can see the background being drawn in real-time.

The file headers are identical between the two rips, so I prefer to refer to this "second" version as an alternate ([a], to use standard labelling) version.

I'd hate to leave it at such a basic set but I don't really have many ideas for good challenges. The lack of continue cheat and warp zones as well as lack of documentation online and the general jankiness of the game means that stuff like and would suck even more than they already did in SMB1 and Lost Levels.

Seems fine, copy-pasting from other sets would not be any fun anyway. Just need to distribute the points.

should we make it 400 points or a bit smaller like 200 or 300 since the set is so barebones and will probably be revised

edit: made the set 400 points. just gotta wait for pc-88 to be official before promoting to core.

Added support for [Alt 1] via Alts, and fixed rich presence for it too; in my tests nothing falsely triggers during the load process, but since memory is randomized feel free to give it a few shots.

What about the World 4-4 Patch?? can you link the Patch?
