My AmigaBASIC library for the Amiga 500. It contains a collection of miscellaneous small endeavours. Some of them are highlighted further below.
My larger AmigaBASIC projects have their own repositories, see:
Put the repository into a mounted directory of an emulated A500 and run the start script (assuming that AmigaBASIC is installed in mounted Basic):
execute AmigaBASIC
You can also start using the workbench (info-files provided).
Some programs make use of my Assembly subroutines. Their sources are found here.
The diskfont.library is the only OS routine for which relative paths do not work. Hence, it is put into the src folder.
An early platformer-like game that test the player's dexterity (and his concentration, of course). Nine levels of increasing difficulty are provided.

An early 4x game in a time before Civilization 1. Four human players compete on a 21x21 for resources, skilled workers, and more. The only completed part is the map and the economic model.

Have you ever dreamt of creating a mod on the original Amiga version of Sid Meier's Pirates! on the Amiga? With PiratesModCreateFork, a new mod is forked from the main game (original disk required and not part of this repository). This includes replacing the map (example for the Indian Ocean is data/PiratesMod/IndianOcean), replacing countries (e.g., Portugal instead of Spain) and resources (e.g., pepper instead of spices). PiratesModMapShow draws the mod map and PiratesModCities provides a means of editing the cities, including all their properties. Finally, PiratesModSplitter extracts only the relevant mod parts from the rez files (about 10% of the size). They are provided in data/PiratesMod/*Pirates.rez.section.
- As a side note, the game is very finicky about the mods it is able to run and may crash at the beginning if the mod goes too far. It is advisable to steadily refine and test the mod to be sure it is runnable.

| The Golden State Warriors in 1993-4. |
TVSportsStatsEvaluator: Reads in the season statistics seasonstats.prt from the TV Sports Basketball disk, asks for the number of games played in this season (not available in the file) and calculates one aggregate "worth" value for each player, which is $$_{FGM1.4-.8FGA+TPM2.5-.8TPA+FTM-.8FTA+.6REB+ASS+1.2BLK+1.4STL-1.4TRO-.3FLS}$$

Dopplerschaukel: Physical engine to simulate the movement of a swing which emits a sinus sound at 1000 hertz. This sound undergoes the Doppler effect and is voiced as if it was heard at the swing's rest position.

Electrostatics: Physical engine to simulate the movement of an electron in a field of one big and one small negatively loaded ball. Demonstrates that, in electrostatics, repulsion is possible whereas in gravity it is not.
