Vice 3.2 Mac OS X

Published on 4. January 2017 in C64 and Mac. Closed

I’ve compiled vice which is now compatible with 10.9+. The official build is only compatible to 10.12. In order to compile it on my system (10.11) I did:

Install Xcode and command line utilities
Download a 10.9 SDK: Old SDKs
Patch the build file: remove the “clang workarounds for now” (line 198-201) of file “build-vice-dist.sh”
Start the build tool: DEV_BASES=/Library/Developer/CommandLineTools/ ./build/macosx/build-vice-dist.sh x86_64 10.9 clang cocoa dmg

Copy sparsebundle to disk on Linux

Published on 27. March 2015 in Linux and Mac. Closed Tags: dd, Linux, sparsebundle.

I’ve figured out an pretty easy way to copy the contents of a OS X sparsebundle onto a whole disk on linux.
First go into the Image.sparsebundle directory and have a look at the Info.plist. You need the values for size and band-size.
Now in a shell enter:
for i in $(seq 0 $(({size}/{band-size}-1))) ; dd if=`printf "%x" $i` of={/dev/sdx} bs={band-size}c seek=$i ; done
All in one line and replace everything in curly braces with the desired value, e.g. “{band-size}” => “8388608”.

Christopher Tumber tweaked the code a lot. Now it’s running at 48 fps (instead of the 25 before). Now it’s playable on a real Vectrex (I didn’t had one when I wrote it). The source with all the improvements is included.

FireWire hard disk emulation

Published on 9. June 2014 in Linux and Mac. Closed Tags: FireWire, lio, sbp2, targetcli.

I’ve discovered a way to use a file on a computer as a FireWire Harddisk for another computer. This is a handy way to work with older Apple computers because it’s way easier than burning CD’s or using a read FW HDD.

The setup is not that complicated but still there is some to do.

New Vectrex Game: P1X3L-pushr

Published on 4. January 2014 in Vectrex. 6 Comments Tags: 6809, Vectrex.

It took some while but here is the new Vectrex game “P1X3L-pushr”, which is a remake of our own C64 game. The game was created for the Coding Compo at the DoReCo-Party 2013. Sorry that it took that long to make it public.

This is our first Vectrex release and my first steps on the 6809, which seems a great processor.

The archive includes not only the rom file but also the full source – have fun with it!

C64: 512k RAM/Module Expansion

Published on 19. April 2012 in C64. Closed Tags: c64, Cartridge, CPLD, Module, RAM.

Last weekend I’ve finished my first CPLD experiment, which (of course) was an project for the C64. This small extension is a GeoRAM compatible RAM extension or a EasyFlash like extension. It’s possible to switch between them via software. In other words you can use it as pure ram or load cartridges in the ram and play (instead of burning eprom modules).
