Re: Dragonwing 2

1 multicolor pixel smooth scrolling works! (Look closely at the tileset character pairs and you'll get it) This looks to be the same technique Misift used for "Cheese and Onion". Two tilesets, switched for 1 multicolor-pixel-scrolling and using $9000 for 2-multicolor-pixel scrolling. Am I...

Re: Paddlescope

[...] the readout should be done in a screen range, where the video signal itself is not overly modulated. Best candidate seems to be during the VBLANK time. Seeing how badly my VIC-20 has paddle-jitter I tried a similar approach recently. I used the stable-raster-routine to set up a raster-interru...

Re: Paddlescope

Interesting! Do you have an old 2-prong-VIC-20 or a newer CR-model with the DIN-plug for power? The digital replacements (Micromys, et alii) eliminate the impact of the comparator threshold, and thus they are not affected by the Paddle jitter. Looking forward to this or even better a small in-betwee...

Re: Display issue

In my experience, doing the S-Video mod and then using a small S-Video -> Composite adapter gives a better picture than the native Composite-signal of the VIC. Or you could look for an S-Video to RGB adapter.

Re: VIC - why 22 Columns?

The VIC-chip was not designed for a computer, but as an arcade-ship for games. Only when Commodore hat lots of 1K-static RAM chips in stock and needed to design a computer around it, they took the available VIC-chip. That's how I understand it from the book "Commodore - A Company on the Edge&qu...

Re: In the making: Arukanoido – an Arkanoid clone

I tried on my real VIC with Rev 736 for 20 minutes just now. No B-block appeared. Also I never saw a P-block in the last 45 minutes (real and emulated). I've barely managed to complete the first level this way. Really frustrating... Although I use paddles, at some time the ball just gets too fast to...

Re: In the making: Arukanoido – an Arkanoid clone

Can't say if it works now, since I never got a B-block anymore in the last 20 minutes of play :( While this may be realistic, for testing purposes can you go back to the old behaviour?

Edit: Finally got a B-block. No sound effect at all. Latest VICE as always :cry:

Re: In the making: Arukanoido – an Arkanoid clone

Latest revision (726) as always in VICE 3.1. There never is a sound with the break-extra (when leaving the level to the right). I specifically checked both digis and normal sound. Edit: This sound at 13:58 specifically: https://www.youtube.com/watch?v=Th-Z6QQ5AOQ&t=13m56s Also found an error in ...

Re: In the making: Arukanoido – an Arkanoid clone

And another test-play with more "dirt" on screen where it doesn't belong. Happened just after entering the level with a B-extra.

Also just noticed the laser can fire through the gold-bricks again, don't think it can on the arcade.

Re: In the making: Arukanoido – an Arkanoid clone

Yes, seems so. In my playtesting I just ran into this: aruk.png Some "dirt" seems to have remained at the bottom after the last level was completed. Also "High Score" at the top is missing a letter. I have also uploaded a VICE-snapshot here, so you can verify memory contents: htt...

Re: WIP: Manic Miner port

Perils of Willy was 16K on the VIC-20. Sadly, I suck at these games, could barely finish the first level. Looks very true to the original though.

Re: New physical cartridge release: Cheese And Onion

Nothing to do with VICE. You can just rip the image from the cart by using an XPander for example by saving BLK1,2,3 and 5 and then start with SYS64802. No special magic about it. Made a version for myself this way that I just crunched with exomizer and can load and run from SD. I cannot share this ...

Re: In the making: Arukanoido – an Arkanoid clone

Just tried playing with the digi-sound. While it may work for the music in the game, the in-game sounds sound really harsh and cause ear-bleeds after about a minute or so. Furthermore, they decrease the frame-rate considerably so that you can hardly follow the ball. When you get 3 balls it's absolut...
