If I set $01 to $35 at the start of every IRQ (before acknowledging the interrupt and setting up the next), and clear it to $30 at the end, my mainline should have access to all of RAM, should it not?]]> ChristopherJam http://csdb.dk/forums/?roomid=11&topicid=98675#98678 Wed, 19 Jun 2013 17:31:26 +0200 C64 Coding: Packer/decruncher for under IO? /tlr http://csdb.dk/forums/?roomid=11&topicid=98675&rss#98677 What problem are you encountering more specifically?]]> tlr http://csdb.dk/forums/?roomid=11&topicid=98675#98677 Wed, 19 Jun 2013 17:07:00 +0200 CSDb Discussions: DolphinDOS 2 and 3 remake /Silver Dream ! http://csdb.dk/forums/?roomid=7&topicid=98662&rss#98676 Quoting Lemming

It's a proto version but it's awesome - as for autorouting and such details, we used white boards as you can see, so not much is visible regarding the signal paths :)


:-) At least the "decoupling" caps don't get reminded too often that they don't really do anything useful :-)

I think once I understand what different memory locations do I might be onto a winner! Many things to grasp in the world of assembly.

I just ordered a beginners book by Shiva which I also have for BASIC programming. So hopefully in a couple of years time I might just be releasing my own demos :)]]> Flimsoft http://csdb.dk/forums/?roomid=11&topicid=96749#98672 Wed, 19 Jun 2013 00:29:51 +0200 CSDb Discussions: DolphinDOS 2 and 3 remake /Silver Dream ! http://csdb.dk/forums/?roomid=7&topicid=98662&rss#98671 Quoting Count Zero

I made a couple of boards of (an earlier) DD2 by Silver Dream, excellent work!


You're welcome!

Oops! You made yours probably using the very first, autorouted proto layout, where the only thing being correct were the electrical connections ;-) I think I sent you the files once, after recovering what could be recovered of the HDD crash...

@Mixer: I think the sprite-shit will be hard to get working.. The faces are just a tad bit bigger than one sprite. That also rules out the popular sprite-filler (by updating sprite x-pos each rasterline), since it would require masking the right edge with a white sprite, and there are possibly more than 4 red ares on one rasterline..]]> HCL http://csdb.dk/forums/?roomid=11&topicid=98269#98663 Tue, 18 Jun 2013 13:51:55 +0200 CSDb Discussions: DolphinDOS 2 and 3 remake /Silver Dream ! http://csdb.dk/forums/?roomid=7&topicid=98662&rss

I've been thinking whether this could be done by rearranging and organizing the animation coordinates by drawing each red face on sprites with somewhat hardcoded sprite filler and then just multiplexing sorted sprites on screen. Perhaps one could even shrink all the continuous vertical edges and expand them with sprite stretcher, however stretching eat precious cycles. Similar approach might work with chars, but I guess the overhead makes it pointless.]]> Mixer http://csdb.dk/forums/?roomid=11&topicid=98269#98660 Tue, 18 Jun 2013 13:08:48 +0200 CSDb Entries: Release id #114706 : C64List V3.03 /jwhoag http://csdb.dk/forums/?roomid=12&topicid=98658&rss
Yogibear: Thanks for the thumbs up! Much appreciated, and I'm glad you like this tool.

sXp: Thanks for the detailed bug report. I'll look into this issue and fix it in an upcoming release.

CountZero: Thanks for the comment. I haven't used PetCat so I can't compare the two products. C64List's machine language-to-assembly text function works well, but I'm certain there are more in-depth tools for that kind of work. I wanted to focus C64List on development activities rather than reverse engineering. My philosophy for C64List is that there should be a one-time conversion from existing programs to the C64List source format, and many times compiling from text to .prg files. So while C64List does have some reverse engineering-type functions (such as de-tokenizing existing BASIC programs and converting them int line number-less labeled text, renumbering, assembly listings, and hex dumps), I put much more time and energy into going the other direction: making it easy to develop and compile source code. I hope that makes things more clear for you.]]> jwhoag http://csdb.dk/forums/?roomid=12&topicid=98658 Tue, 18 Jun 2013 08:48:40 +0200 CSDb Discussions: Modding a C64G /dink http://csdb.dk/forums/?roomid=7&topicid=97784&rss#98657 dink http://csdb.dk/forums/?roomid=7&topicid=97784#98657 Tue, 18 Jun 2013 03:30:59 +0200 C64 Composing: The sid stealing continues! ... /CreaMD http://csdb.dk/forums/?roomid=14&topicid=62860&rss#98656 CreaMD http://csdb.dk/forums/?roomid=14&topicid=62860#98656 Tue, 18 Jun 2013 00:35:26 +0200
