In the making: Arukanoido – an Arkanoid clone

In any case, you should do the readout of the POT% registers only in the top or bottom border area, as there then is least disturbance by the video DMA.

Alright. That sounds like the way to go. Thanks!

Did anybody test the WAV with real tape yet?

[darkatx]

...
Some other good news: darkatx just jumped in to do the cover art again. (He did the artwork for PULSE too.) We're very excited about it, working on some top-secret eye-candy for the tape version, making sure this release will knock everybody in the balls. (Unless it's impossible to do so...)

Shameless promotion of Work in progress

For a WIP Picture that is LOVELY ! So am I right in thinking there is a Physical Cassette Version being Released ? You Guys are SUPERB !!!

Maybe.

Here's a new update by beamrider making a compromise with volume 6 tops:

Yummy ! Thank You

T'was a good idea to take a little break. The brick animating code spoiled the zeropage. Here's the fix. Hiscore table input is still kaputt.

There seems to be some issue when the warp gate is opening and sometimes a round ends although there are still some bricks left. That's three real bugs left so far.

Hiscore table item insertions fixed and paddles are read off-screen during VSYNC to reduce jitter.

@tokra: OK now or still too much jitter?

Jitter seems better now. On the hiscore table I could finally enter my initials. I still have to be super careful, but at least I am able to get each letter stable now.Ingame jitter seems a little better as well.

On first start at the game I got the same error as last time again, the flickering raster effect of the engine was missing and only the bottom right corner of the screen was flickering (in the border area). Will try to get a video next time.

Hmpfhmmh. That's still a bit disappointing. There's double un-jitter with the hiscore table now. (NMI + add/ror)

Must be a prob with the real thing. Interrupts are disabled on sync. Looks like a problem waiting for the VSYNC in Mike's code.

Please check if any of the points in my most recent post w.r.t. the raster engine might be relevant here.

This revision (#1576) pulls out a bag of tricks to avoid frame skips and sprite engine performance has been improved as well – of what use would an unplayable three-ball-mode be? Made possible with help of chatGPT-4!

In rev. #1576, the raster effect at game start is distorted:
