It should be possible to decompress a number of packed games, however not all of them!
Early CDÂ’s such as LSD/WNW used one off specific file headers with the depack code included in the loader. These could be depacked but youÂ’d need to know exactly what you were doing. However more standard trap #1 packed games should be unpackable, IÂ’d use XerudÂ’s Unpack or MugÂ’s Multi-Depacker, Unpack is available at the PHF site (http://phf.atari.org
) - in hacking toolsÂ… Multi Depacker should be downloadable from MugÂ’s own site Â– http://come.to/muguk
The problem is that many games arenÂ’t hard disk installable so you would still need to patch the loading code. They often have Drive A access hard coded into the game.
The other problem lies with games :- link-filed, lumped, dackloaded., ziploaded, andyloaded, cameolink, vaploaded, Wandererlinked etc phew! Again all these games canÂ’t be decompressed with a generic depacker like Unpack or Multi-Depack.
I agree that the colour flashing whilst games depack is annoyingÂ…. In the short term you could always NOP out the reference to $ffff8240.w . Thankfully the vast majority of D-Bug games donÂ’t screen flash, plus they use highly optimised depack code which decompresses much faster than the old Automation / LSD packer.
