Any ZIP/RAR/7Z utility should do that. If the program does not recognise the file, rename it to .adf.gz first.
The original tool is gzip. Don't know if there is a Windows binary, but every Linux distro contains it.
Thanks! That's what I thought actually, just needed to be sure.
I suppose any windows starting from XP can natively unzip files, also gzipped ones (with some exceptions). Mac OS X has gunzip console command, also one might unzip files by double-clicking the file, just like in the windows case.
One more issue then, there's a silly need by UAE4All to have Kick.rom file prepared to have 512KB. Unfortunately Cloanto's AF package has 256KB files. I was told once here, by bloodline I guess that I should just clone and concatenate the file. And it worked but now I forgot how I did it.
So from any user's perspective (Win/Lin/OSX), what's the easiest way to merge two files? There is a cat Linux/OSX command but the file is binary, not sure if it leaves it unbroken... And in Windows case... no idea.
Of course since I got the AF files, I can always get the p!rated 512K file hanging on the internet. But that way is a silly one. I want the solution, not a conditional workaround.
