Adorable!

Yea. I'm plundering around with the example code, mostly optimizing it to get scrolling to work smoothly. Originally I was copying all bytes after 4 dual-bit shifts, but that takes a really long time and is a real waste. Now its only copying the bytes that contain something.. but I will improve tha...

Sweet! Fantastic work, Heaven! Great to see the Vic-20 reppin' again this year!

Mermaid's work is truly inspiring. It's great to see another Vic-20 release from her.

Thought I'd drop a mention for this since I haven't seen it posted yet. The Vintage Computer Festival Midwest, and ostensibly ECCC (though that website hasn't been updated for 2017), will be happening in just two short weeks! I'll be making the long and expensive journey through the many toll roads ...

Looks like it was a lot of fun! And really nice picture, tokra! Hope you've all had time to recover.

Merry Christmas!!! I hope everyone has had a great year! In consideration of the Europeans I stayed up til almost 3 "finishing" this in hopes that some of you might find it before Christmas is over...but not with so much consideration as to actually release a PAL version. Sorry, you'll ne...

The demo "No Pets Allowed" makes use of another technique. The screen size is reduced and the characters are only partially displayed. By choosing the right characters, you can make a bitmap image. Yep, I thought the concept of bitmap graphics was was all you were after. I'm curious to kn...

Last year I acquired a CBM PET 4032, which contains a CRTC controller IC (6545) and I wonder if it could be pushed into the same trick. I still have to closely examine the schematics and the chip itself, but imagine the possibilities if we could break that boundary of a character based display into...

Yeah! Can't wait!

Should i be concerned about overheating when it comes to the two prong model? As has been said, it's pretty normal for them to run a bit warm. Many people reccomend putting a heatsink on the VIC (6560), but that's a separate issue. Unless you want to install a fan, there's not a whole lot else you ...

When the VIC accesses unconnected space on the VIC-20 and instead takes its pattern data from the instruction and data stream of the CPU, this is another mechanism at work. There are no known cases this would corrupt the internal RAM, and also the schematics of both mainboard revisions don't indica...

Very nice little demo and great to see another PWP prod! :) The checkerboard/whatever zoomer in the background was done with VIC accessing unconnected space. :P There was some debate on the consistency of that technique years back (even from Viznut himself) across board revisions, right? Did those i...

Sweet, those are some great feature additions! Thanks for the Halloween treat, tlr!

I'm not really sure how you came up with those numbers, but... Sorry, I should've elaborated. I didn't know if you were updating color or screen or... so I just did 3*512 for writing zp/stack, 4*(968-512) for non stack/screen, and I guess the rest is obvious. Just disregard that nonsense though. :)...
