The unfortunate thing about RetroArch making thousands of bucks a month off the back of other emulator developers who don't see a dime? I could download, decode, analyze, and encode a swath of Laserdisc games for use in MAME if I had a capable enough Ryzen machine.
Agreed, I just wish I could use the offers to distribute the load. The problem is, sharing LDS/LDF files with other people to analyze involves much the same issues as directly sharing ROMs with other people. There's a reason why MAME dev typically keep dumpers at arm's length.
