Ok, first ALPHA release DEMO of these "software sprites" is available. :D Download it here: DEMO cartridge @ $A000 ... and its assembler source code using cc65 project. It supports NTSC (default) with a startup override to switch to PAL timing. Press RUN/STOP to pause frame. Still 8x8 onl...

Hi,

I have seen games like Shamus able to do amazing smooth graphics, instead one character at a time. How is that done? I would love to learn how to do this?

Thank you!

Pin 18 is unbuffered and will cause problems. If you look closely at the board for VIC-1110 and VIC-1111 ram expansions, they also use pin 17.

Thanks, eslapion for the tip.

And, WTF made you think it would be any good to *connect* CR/W and VR/W? Easy there...You think you know everything about the VIC20 with an attitude, huh? Get a life dude. Seems like you've promoted yourself with tons of posts that frankly people don't care of your answers. People like you, who I h...

And "VR/W"...I think you meant the "CR/W" signal, because the "VR/W" is to the VIC video chip, no? *No* *I* *meant* * V R/W*. Does not work at all for some reason. I short out the signal from CR/W, which is connected to /WE of the SRAM chip and does work with 24KB of /...

Why the "while(0)" is in the define? I know it's necessary but forgot the reason.

Can VFLI mode be done with RAM expansion board via the cartridge port, that is, without doing the hw modification you outlined?

If i have RAM installed for BLK5, starting with $A000 address, which is the address for ROM. What makes you think, that a chip connected to the /BLK5 select line on the expansion port "has" to be a ROM? How would I tell the VIC-20 so that I am able to write to it? If this is a RAM chip, y...

Hi,

If i have RAM installed for BLK5, starting with $A000 address, which is the address for ROM. How would I tell the VIC-20 so that I am able to write to it?

Thanks!

Hi,

I did some searching (via google.com) not able to find a sample of VIC20 emulation code for the cassette player. Would like to know of the protocol, and looking to do a firmware DIY project of loading files from the cassette port but via a modern microcontroller and an SD card.

Thanks!

Excellent thanks, that helps a lot. I have edited One of the photos You posted to show where the AC signal travels. Measure between the red and blue starting at the AC input and see how that goes. http://i62.tinypic.com/4u79d3.jpg Ok...Just to be sure I resoldered the inductor's through hole connec...
