Re: are some sprites encrypted or compressed?

Depends on the file you’re using. If it’s a TZX, the data could be encrypted. Also depends on the selection width, due to alignment. Best to use a RAM dump, rather than a tape file (but some date could very well be compressed as well).

Re: Guess the screen$

Well, I see this one’s proving to be too tough. Here’s another clue, then. The game starts with a fake system tests (including RAM, ROM, character, and sound tests). The “test” takes an annoyingly long time to “complete.” But, if you hit BREAK, the “test” will exit and take you to that 1882 message....

Re: Unevenly scaled pixels in screenshots/videos

Maybe on some small subset of screens, but I did refer to a "typical 1980 TV set", TBF - and generally talk about the kind of screen used with the world's most cheap-ass computer. This is an early 90s set. Pretty sure it’s a Sony (took it several years ago). I agree, it’s not your typical...

Re: Unevenly scaled pixels in screenshots/videos

Some add . . . the horizontal "scanlines" that just weren't there. Actually, they were. Mostly on larger sets, and definitely on Trinitron tubes. Perhaps, not as pronounced as some emulators approximate them, but they were there. My current 14-inch CRT, however, doesn’t have any scanlines...

Re: Another newbie here to fix his 48k spectrum

A tip for cleaning the vias quickly: dip a toothpick in melted rosin; then heat the via with a soldering iron and stick the toothpick in it. This will clean up the hole in no time with no damage to the board.
