Re: OK, here's the ultimate volume boost trick for digis.
Nice trick! The sample playback itself is handled by the volume register I assume? While this trick tries to make the average sound output as high as possible on average?

Re: Pre-Orders: Final Expansion 3 Rev 11 [3rd Batch]
Hi!
I have one that I never got to work.. a pity. I'm interested in buying one from you though I already have a dark casing to go with it.
Cheers,
Johan

Re: A port of victracker from DASM to CA65.
All the hard work was done by Daniel Kahlin, who wrote the tracker. But yes, the tracker has 4 channels, one for each VIC sound channel. I just ported it to be compatible with the ca65 assembler.

Re: cl65 linking problems with a vic20+16k
That's true. The memory layout comes from the fact that I wrote the game for the VIC20+3K... although it started out as a game for the unexpanded VIC and because I was not yet very familiar with the VIC20 memory layout when I started this project. So I included the assets into the program and the pr...

cl65 linking problems with a vic20+16k
Hi, I'm trying to port a game I made for the VIC20+3K to a VIC20+16K. However, I can't figure out how to let the linker generate a program that fits the memory layout of the VIC20+16k. I put together a small repo explaining the problem I have... https://github.com/nanoflite/vic20-16k Here's the READ...

Re: Warning by viznut/pwp
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. Ah, I will need to read up on the DMA technique then, but I doubt if it is applicable to the...

Re: FE3 - Recovered Technical Documents from lost website
It is rev. 0.9 of the board (http://www.sinchai.de/index.php?main_page=page&id=5). I double checked polarities of the components and verified pin orientation of the ICs. What happens is that the sd2iec LED flickers, but when trying to access the SD card, nothing happens. I also see the 'normal' ...

Re: Warning by viznut/pwp
Nice... really nice! I think I understand the trick being used in the unconnected space graphics mode. Basically, the VIC reads pixel data from the data bus and with some tricks you can align the VIC reading the databus with the operand of the instruction, not the opcode. With some self modifying co...

Re: FE3 - Recovered Technical Documents from lost website
I assembled a 0.9 version and cannot get it to work. I really would like to get it going as I'm developing some retro games for the C64, VIC 20 and PET 4032. It looks as if the firmware is not in the Atmel and / or CPLD. Has somebody else also struggled to get it to work?
Cheers,
Johan
