Vice 3.2 Mac OS X

alx — Wed, 04 Jan 2017 22:19:54 +0000

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

Update: compiled Vice 3.1

I’ve just published my 6502 code reorganizer which results in a better compression:

C64: 512k RAM/Module Expansion

alx — Thu, 19 Apr 2012 10:32:18 +0000

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).

This is only thought as an experiment for me to learn to deal with CPLD. So far it’s working as it should and I’m happy ;-)

The used Parts:

an CPLD: Xilinx XC9572
512KiB RAM
74hc365 hex buffer/line driver
a led (with a 1k5 resistor)
sockets, circuit board and wire

C64 Reset using the Restore key

alx — Fri, 26 Aug 2011 14:03:26 +0000

With this small device you can reset your C64 by holding the Restore key down by 2 seconds.

All you need is an ATtiny and a little more, the price should be less than 2 EURO in total.

Code/Docs: C64 Reset by Restore

Updated 2017-09-09: Hold the restore key longer to perform a second reset.

C64 Converter

alx — Tue, 04 May 2010 13:50:09 +0000

We are working on a new and much better converter. Until that is ready to use, you can still user the old one.

Convert an PNG/GIF/JPEG to C64 FLI/KOALA (image must be 160×200 or 320×200)
Just select an image, press “Convert” and look/download the converted pictures.

For best results reduce the colors in your image to the 16 colors in this palette:
