I was contacted by someone who couldn't make the appimage from about 1 year go to work, it was 0.93.x version, with very old dependencies... So this time I took the time to create a virtual machine to test this in mint 21.2 (which I don't like a lot !), and the appimage got a few updates (only the 64 bits version is updated, I have currently no setup to build the 32 bits version so I must restart it from scratch and it would take too much time). The audio seems slightly delayed in the VM, but except that everything seems ok now, couldn't contact internet archive but it was a VM problem, I should add a cancel button to the curl dialog but it will be for another time ! By the way this fat archive weights 16 Mb which is about 8 times the size of a normal release !!! At least you get all the optional data files + the dependencies inside, and it should work on any linux distrib having at least glibc-2.29 (which is very old, it's bionic ubuntu). It's a last resort if you can't install any normal version...
And there were a few bugs in accessing some files in the appimage which pushed me to fix quite a few paths which were wrong also for windows, it's a miracle that some functions worked in windows, maybe I didn't test them enough, and it explains mer-curious problems with the ips files ! (and it's a crazy bug, sometimes a path with / is accepted, but sometimes not).
Anyway except the big heap of paths fixed, there is the 2nd fix for the default value of speed hacks in neogeo... !
Hoping it's the last time I cope with these silly bugs ! But the experience in the virtual machine was interesting anyway... !
