Test-file generator?
Has anyone written a generic test-file generator for testing loaders/savers?
Preferably generating files of arbitrary length and start-address containing random data and a self checker.
I want to test some turbos, and want to quickly be able to see if there are errors with different timings and end alignments.

why doesnt some random one filer games do ? writing such generator on PC and then xferring to c64 is a piece of cake aswell. |

Absolutely, but I don't want to write another one if there already is one perfectly good. ;)
One long file will work for testing timing, though you cannot always be sure it doesn't start if there are very few bit errors.
I also need to exercise end offset alignment within the last block and stuff like that, so I need to have a selection different lengths.
I'll write a small generator if there isn't one. |

:)
It somehow misses to output a self checker (atleast most of the time).
