I wonder if the CPC version took any inspiration from the C64 source code? Sure it's Z80 vs 6502 but I imagine that some of the ball physics stuff could have been useful. But they might have written everything from scratch as well.

Darn. What timing. Now I'm sure to be harassed during X16... Aargh!

Looks really nice though! I also wonder what they're doing. Keep in mind they have a faster processor (4mhz) and more memory (128kb) though..

Some would argue that a 4MHz Z80 isn't really faster than a 1MHz 6502...

Something seems off with the ball physics in the CPC version. In WVL's C64 version (and of course the Amiga original) the ball curves smoothly around the ramp bends, but in the CPC version the ball jerks and loses speed. Also when the ball launches it just falls like a dead fish.

Compare:

They've nailed the graphics engine and the music though, so with some physics tweaks it looks like a really nice port.

PS: Mr SID, they'd be wrong, especially if you do 16-bit math and addressing. IIRC a 4 MHz Z80 should have at least 50% more grunt compared to a 1 MHz 6502.

Had to cancel my x-trip.. :( my wife is just waaay too pregnant. :D if you wanna finish it plz contact me on FB and we'll setup a modern dev-chain and just do it. All the hard stuff is done.

Pantaloon: please ask your bosses if they have the score-rules for the game stashed at Dice somewhere.

The Effective CPU speed on the CPC is 3.3 MHZ (Google for: Z80 timings on Amstrad CPC - Octoate.de Wiki)

Just a comment on the instances where the ball and/or scrolling seems jerky on the youtube video posted on Pouet. There's still some trouble with capturing and uploading CPC emulator videos on youtube.

This videocamera capture of the real thing should be a more accurate example. https://m.youtube.com/watch?v=-tcsxUtMj5I

Having written the above, I still havent run PD on a real CPC yet.
