ivop's Blog > Reverse Engineering the Macro-Assembler XE File Format

Posted 30 January 2010

On the Atari 8-Bit Forum, Heaven/TQA asked for help with retrieving an ASCII version of his demo sources in Macro-Assembler XE format. Because I recently wrote a detokenizer for Mac/65, I thought it'd be fun to try this file format too. Here's the result. It successfully detokenizes all the sample .ASM files I found in his zip-file, but...

ivop's Blog > demac65: detokenize MAC/65 files

Posted 21 January 2010

While I was browsing some old source code, I frequently stumbled upon MAC/65 tokenized files. Being too lazy to repeatedly start an emulator to convert them to (AT)ASCII and being unable to find a program online to detokenize them, I set out to write such a program myself. With some luck, I found a description of the format in the form of an old...

Posted 30 October 2009

Here's the 6502 assembler I mentioned recently on the Atari 8-bit forum. The reasons to write this were:

1.) None of the assemblers I tried could generate correct code for code assembled to run in zero page and have forward references to other code in zero page, changing their operand in real-time.
2.) I wanted to write an assembler in sh...

ivop's Blog > Turn monitor off in console mode Linux on an iMac G3

Posted 20 August 2009

Recently I acquired an old Bondi Blue iMac G3 with a PowerPC @266Mhz and 64MB RAM. I upgraded the RAM to 128MB and installed Debian GNU/Linux on it. Runs like a charm. I intend to use it remotely to test big-endian compilations, so I wanted the built-in monitor to be turned off. After searching the net extensively, I was unable to find a solution....
