Nostalgia in Parts

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.

Let's roll with a small demo.

FC64 player

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).

Dig it like it's gold

Phew... the waiting is finally over! Just got my hands onto the fresh re-release of the C64 emulator for iPhone/iPod Touch from Manomio. After long months of impatience, the Retro vs Apple war has calmed down - the app is back in the Apple store. I missed the previous release by seconds, it was immediately pulled out from the store after discovery of hidden BASIC interpreter (nota bene by Microsoft – was that a real reason?)

C64 emulator for iPhone by Manomio

After trying out all the games must say I felt a little bit disappointed – where are the classics like Bruce Lee and International Karate? They were there before!
We've got 8 games instead: Arctic Shipwreck (one of the first filled vector graphics on C64 in 1983!), Dragon's Den, Jupiter Lander, International Basketball/Soccer/Tennis, Jack Attack and Lemans. I'd love to see Boulder Dash, Pit Stop, Spy vs Spy and other exciting titles. There's some hope with the new Apple in-app purchases though, but the question is how much we would need to pay for a game?

Me likes

  • Retro coolness – concept and detailed graphics, it's all sweet and shiny
  • Overall performance is great (worked well on my 1st gen iPod Touch)

Me picky

  • Default selection of games could be much better (more classic titles!)
  • Touch joystick controls a bit too sensitive (it's a bit funny to learn how to drive for the first time), adjusting it would be a nice feature
  • The screen highlight in the landscape mode is a bit too bright, it should be adjustable

Me thinks

  • The game area is covered too much by the monitor frame in the portrait view but I understand the reason for it
  • It would be nice to add some demoscene productions, at least one one-file demo/dentro should be included with 1.2 release!
  • SID emulation quality hard to estimate, most of the games from 80s didn't have fancy music/sfx
  • Maybe use Vice engine instead of Frodo, it's still under active development and has more features explanation
  • I would add another landscape mode: 384x271 px (full C64 screen including borders)

Another thing I need to say is that I am totally against Apple's policy of controlling the content of my very own device, my dream is that one day (wishful thinking) I will be free to to upload and run any kind of binary data in the C64 emulator. Imagine going further and having real hacking like this on your pocket friend! For pure fun.

But to be realistic, I guess it would have to be Android.

Thanks Manomio!

UPDATE
The guy known as DNA is trying to re-enable BASIC as he believes it's not been completely removed (which might be true as some games may still use it.) He had succeeded to enable keyboard before by using SSH on the jailbroken device.
Fingers crossed for DNA!

On another hand, Stuart Carnie – one of the iPhone C64 app developers, posted a video of working emulator (which was based on Vice and Frodo). I'll be trying to get my hands on that.
