Hello all, have some question. I have a menu where you choose what must be loaded, when exit a loader is loading the file. when exit the loaded file i wanna load automaticly the menu again. Is this possible to do in the startup-sequence?

Gr,
Jarre

Sure:

lab start
Menu ; run menu
loader ; load and run selected file
skip start BACK ; back to start

Another question, say i have code in memory from $25000 to $7ffff, i crunch this data, how many bytes below $25000 i have to load this file to decrunch it perfect..?? Never understand how crunchers work and not overwrite themself. And which cruncher will decrunch the fastest..?

That depends on the used cruncher or rather the decruncher code. There is no general answer to this question.

Which cruncher is fast in decrunching and have less bytes to load before $25000..?

You need to use a cruncher which allows decrunching over the source data. RNC Propack for example will work, the CrunchMania decruncher allows that too. Decrunching almost 400k will still take a while on a bog standard 68000 machine though so it might be a better idea to split the data into several chunks and decrunch/load/copy them on the fly. This depends on what you are doing of course, why do you have such large area of code/data you need to crunch?
