Nope. It’s the one true, most natural layout for me. Still opt for it in modern PC games.

Pretty identical to what I have (except I chose to ADD rather than SBC, because it’s 4 T states faster). Storing the subtrahends in a string is really clever, though!

Neat! Some time ago, I came up with this (as a base) for displaying the score and other stats.

Not that impressive on a stock Speccy. I get about 2–3 fps (depending on the scenery).
But it’s a neat proof of concept nevertheless!

Hard to tell without looking at the actual port read routine, but on the off-chance that you’re using prime registers, HL′ needs to be saved. You could do exx ;\ ld (saveHL+1),hl ; needed for the BASIC interpreter (routine at $3362) exx ;/ Then fetch it back before returning to BASIC. Then again, ru...

That didn’t take long . . .

Nope and nope.

(Reposting the pic, since we’re on a new page.)

What I don't get about the game is that it was apparently designed by David Whittaker, yet doesn't feature any of his music? The result is quite a spooky and tedious game that could have been a lot more fun. Agreed. Still, a very Spectrum game (probably because of the above). Okay, my turn: https:/...

Hocus Focus.

Still don’t understand why people are so adamant about shying away from this.

Brilliant! Your turn.

Well, it’s been a while, so . . .

Nope. Not even close, I’m afraid.

It’s not Marsport.

I don’t think it’s much of a clue, although there are a couple of other oddly spelled words elsewhere on the screen.

We’ll start small:

Bloody hell! Ever since you posted the first pic, I’ve been trying to remember the name of the game. It’s been on the tip of my tongue for hours. Is this what senility feels like?

Anyway, it’s Legions of Death.

Yes! Over to you.

Nope.

It is a radar screen, but it’s not a Defender clone.

That means the CPU is at least someone functional.

Try removing the ROM IC; see if that affects the garbage on the screen in any way.
