in 9.0 beta 7, the platforms that have .lnk as rom, were losing roms, even one of them remained at 0 and then disappeared, while launchbox was running (example 9 .. 5 ... 0 .. then disappeared)
The funny thing is that the .xlm is still in the DATA folder and I do not notice anything strange in its structure.
I'm not sure if something similar happened with other platforms, since those were the ones I was editing at the time that happened.
