Re: A request for new tags

I think the tag itself is a great idea. However we still need to sort out the details. For instance, Castlevania has many bosses but it's a continuous game. Therefore they are neither end-level bosses or end-game bosses. Also if there are too few games in this list, we should probably have a single ...

Agreed. The second Bug Byte release was already marked as 1988.

Agreed.

No, we don't have any material from the first Bug Byte release. That's explained here.

Re: Cricket?

Yes, the code is completely different, but I still suspect the graphics are too similar to be just a coincidence.

Perhaps the same artist created the graphics for both. Or perhaps one of them copied graphics from the other.

Re: RZX link not downloading properly

I don't think it's appropriate to mark this title as denied, since nobody denied it.

But when a game is hosted at Itch.io, I agree it's better to ask the author's permission first, because many titles at itch.io are for sale (or asking for a donation).

No. You have to decompress it to a continuous memory area first, before drawing it to the screen.

Re: ZX0 with prefix at arbitrary address

i'm trying to use ZX0 compression with prefix, but as far as I can see, the prefix table must be at the beginning of the compressed data (and It Will be skipped when decompressing). Correct. Here's the idea: Suppose a certain game have player sprites stored in memory between address 40,000 and 42,9...
