Thanks Keith. I enjoyed your review of Galaxy. I used to play that with a friend on my Atari 400. I'd forgotten that indeed you had to keep your own notes about what you were up to. I have since tried to find another copy of the game, as my original cassette has since failed (as expected). I've trie...

Yeh, the cc65 conio library just links into the kernal routines. Good for keeping the code size smaller, but doesn't solve the variable screen size issue. It does, however, use the vector address, so I may only need to replace the kernal routines. My first thought was to just duplicate the kernal ro...

Thanks for the info guys...that's exactly what I'm after.

I've been attempting to get some code working using CC65 and I've run into the problem where the VIC-20 kernel doesn't handle the actual screen size, but only the default screen size. I've done a bit of searching and have been unable to find much discussion of this, but I'm guessing that I'm not the...

An interesting announcement was made by Uz regarding CC65 that has the potential to impact/improve things for VIC-20 programmers. The introduction of multiple linker config files maintained per platform. The announcement can be found here. http://www.cc65.org/mailarchive/2009-09/6952.html So have a ...

I've done a ROM autostart in assembler for cc65 a few times. Maybe this can help jumpstart your efforts with a C library: This is great Robert. It will require some modification to allow it to be used with C code, but it includes some really good features. I'm looking at how the features could be i...

Bump! :lol: I was going to start a new thread for this, but I decided to bump this thread instead, since it seems fairly relevent. (If the moderator disagrees them by all means move it to a new thread.) I've started trying to capture some of the VIC-20 specifics of coding in C using CC65 in the Wiki...

No. 17 has winged its way across the oceans all the way to it's new home in Oz.

I tend to agree with you Carlsson. It would take a while to perfect all the unintentional side effects. The VICE implementation could be used to enhance the requirements beyond the original spec. I'm not sure how complete VICE is, but it plays most of the modern demos. I'd say it's a very non-trivia...

If you were going to the effort of reproducing the whole hardware of the VIC-20, would you use all the individual components, having to use an FPGA for the VIC I chip, or would you just pack everything into the FPGA al la-FPGA Arcade? This would in effect make it like the C64 DTV. I know that in our...

The solder sucker I use is just a cheap spring loaded manual one, not one of the de-soldering stations. I find I get best result if I don't push it flat against the board, but allow it to suck a small amount of air as well as the solder. If it's pushed flat against the board, it doesn't spring back ...

If you haven't damaged the holes when you remove the chips, the plated through holes should wick the solder through to the other side of the board as well as the bottom. The holes actually have metal sides connecting the two sides of the board together.

I think that's why Commodore datasettes are so much more reliable than those from other systems. I always got great performance from my datasette (while computer cassette decks seem to have a bad rap among Atari & TRS-80 ownders). I was unfortunate enough to have experienced the Atari cassette ...

Another thing that can help the solder to get sucked out cleanly is to add more solder to the pad before sucking. The fresh solder adds flux which helps the solder to flow better, and hence get sucked out easier. Sometimes I find I may have to add and remove the solder a few times before it comes ou...

Hi Hawk where did you get the Image editor? I have looked all over the place on the Internet even a lot of the Adobe Picture editors and none will convert to 160X100 and drop down to 16 colors. Will a lot of other Image editors like X-inview do this? Hi Terry, I can't remember what I was using at t...
