The nostalgia definitely came back. With the recent re-release of the C64 emulator for iPhone I felt that I am somehow thrown back into C64 world again – the only difference is that I am twice as old as I used to be when being active on C64 demoscene and it feels a bit tight. Some time ago I bumped into this amazing ICU64 project - realtime debugging/hacking tool by Mathfigure. Do you remember Matrix the movie?
The first part
I sooooo wanted to have all that working in AS3, that I have resurrected FC64 – low level C64 emulator written by Claus Wahlers (Codeazur) with Darron Shall. The code was moved to GitHub recently, so I just had forked it and thus give it its new life.
Click to activate and watch this (very buggy here but interesting) part from Parts, great demo from 1995 by Oxyron.
Red and green indicate memory write/read, grayscale map represents memory values.
Click on the map and use mouse wheel or +/- keys to zoom in and out. (Memory debugger idea shamefully borrowed from Mathfigure.)
The demo itself doesn't play nicely with FC64 and it's quiet as there's still a lot of work to do on the emulator, but just pay attention the memory snapshot – discover how data is being populated in the memory. The image of girl's face is decompressed and overwrites BASIC area.
I am kind of quietly hoping to get other (ex-)demosceners involved to cooperate and improve FC64 as there's loads to do. The most important thing is to re-enable the SID (maybe using Ralph's TinySID alchemy port) as there are traces of early SID implementation in the FC64 source.
There's another idea for a secret project involving KickAssembler, but shhhh for now...
...and yet another part of the same story
Yes, there is more to it. I am supposed to work on the HTML/CSS templates for the new, cool (web2.0) version of Intros C64 - the biggest online C64 cracking intros repository. The design (also be me) has been approved a year ago, and I am somehow in stuck in the middle - need to work out the roadmap.
Anyway, I wrote a tiny a little bookmarklet to enable live preview of the intros, here are two example links:
And the Bookmarklet itself - just drag the link to your toolbar and use on Intros C64 site (you have to select an intro first - get the view with the comments).06:30 PM | posts | 0 Comments | Tags: c64, experimental, retro, debugging, as3, sid, bug, source
