Old Stuff

BIN2IHEX

Yet another tool that converts binary files to Intel Hex Format. For a detailed description of the Intel Hex Format please refer to the specifications from Intel Corporation (e.g. here).
The tool is written in C++ and should run on all Linux/UNIX platforms. It uses Extended Linear Address Records to specify bits 16-31 of the Linear Base Adress (if they are not zero). Extended Segment Address Records are not supported.

WALLS

It was back in 1992 when I wrote the little arcade game WALLS for the ATARI Portfolio. For those who are still using their old ATARI, here is the link to download it:

Download WALLS
I was asked several times why the game takes up so little memory although it contains so many rooms. The main explanation lies in the programming languages I used: WALLS was written in a mixture of FORTH and assembler code. As for the rooms, most of them are not explicitly stored in the code but calculated following some simple rules.
However, the program needs 20kB of memory and you might want to use the program DIET.EXE to make it even smaller (8 kB!). You will find DIET.EXE or even an already packed version of WALLS on many of the shareware directories in the web. Consult your favourite search engine.

Back in the old days I was a proud owner of a then state-of-the-art "Color Personal Computer" Amstrad CPC 464. In 2006, when going through old papers and disks, I found an executable of a little game I programmed at that time. I never gave it a name but it was on a disc labelled "SP", or "Spiel", so I think I will stick to that name. Please don't ask me to publish the source code -- I haven't the slightest idea where it is. I remember that it was written in Z80 Assembler .... and long!

If you are familiar with a CPC 464 emulator you can download this disc image:

Download SP

I tried it with the Linux version of the excellent CPC emulator "CPCEMU" from Marco Vieth and Rainer Loritz. However, since there exists a de-facto standard of the CPC disc image format I am sure that you can use it with other emulators, too.

Have fun!
