Packing anno 2015
Hi guys,
It's been a few days since I wrote Sledgehammer 2 and I am pretty sure the scene has evolved somewhat since then. So, I wonder what's the latest and greatest in terms of packers? Specifically I am looking for a solution I can use to pack/unpack parts of memory. Not loading - just in-memory.
In this wonderful open-source world I think sharing is caring and there really is no reason to write a packer/depacker myself if somebody else already did :)
cheers and a merry Christmas!

exactly, roughly as a rule of thumb around a third faster, but depending on loader/depacker combo. |

It really depends on your requirements. Single file demo compo and parallel depacking's not an option; same with pulling data off a cartridge.
Must admit though, even for a single file I could have done with Spindle's level of automation when I was putting Reutastic together; spent a while chasing a bug because I'd run some init code for the second page before I'd decrunched the data it required. (As it happens I used Nucrunch because I had the source to hand, but last time there was a comparison post it lagged a little behind the competition) |

Now I'm using the Exomizer in the plugin for KickAss. Works great.
However, when I crunch a section in memory. The crunched data is located at its destination address already. How can I decrunch data at a different destination address? |

It's possible, for expample
exomizer sfx $XXXX foo-in.prg -o foo-out.prg -n -Di_load_addr=$YYYY
will decrunch your data to $YYYY which is also the address you jump to for decrunching. After decrunching it will jump to $XXXX

German, but code is code and I guess you as a Dane will get the message :) |

Thanks Ryk. sfx was the wonderbutton I was looking for. I hadn't thought that I could just use the commandline cruncher to prepack the files :) |
