Gzipped adfs work though (.adz). Your Pandora can gzip.
Do for example in the shell:
gzip turrican.adf
You get turrican.adf.gz => rename this to turrican.adz:
mv turrican.adf.gz turrican.adz
You can load this adz in UAE4All just like an ADF.
Keep in mind this only works with gzip, not zip (gzip =/= zip).
