Yet another evening project to code up old-schoold rotozoomer in x86 assembly with real mode DOS as target. The assembled binary code is around 340 bytes, the included image is 17,408 bytes.
For convenience rotozoom is written in MASM syntax but is easy to port to NASM/FASM.
To compile (using MASM 6.11 or higher)
ml src/rotozoom.asm
The most convenient way to run is through DOSBox. To launch in the DOS command prompt, type
rotozoom.com
You should see the following output
