@iainjh No problem! I've also made some tweaks to AmiBerry so the keyboard can open up the menu when using an iPac controller! I'll see if I can push it through git too as I have some other amiga tweaks for retropie.

Great. I have learned a lot more the last couple of days and feel more comfortable in clrmamepro. Everything is working. Some dat files may have a crc that doesn't match one of the files inside the rom zip, but it works. Also, thanks for that screenshot because you just turned me on to "Hashtab", what a great little utility!

@hansolo77 yes

@DamnAlex Glad to hear it.

Hey @BrockBoyts I'm using lr-fba-next with romset 0.173 (fba 0.2.97.38) in RetroPie 4.0.3 on a Raspberry Pi 3 and TMNT: Turtles In Time seams to run fine for me. I have both tmnt2.zip and tmnt2po.zip and they both work great. I also have an unknown romset (I downloaded when I didn't realized you had to have romsets for different versions of MAME when I first installed RetroPie) that I'm using with lr-mame2003 and have 3 versions of TMNT: Turtles In Time and they all work fine as well. Do you have a tmnt2.zip.cfg file in your ~/RetroPie/roms/mame-libretro/ directory by chance? (or whatever your ROM file is with .cfg after it?) If you haven't already, you might also try updating the RetroPie-Setup script and then update lr-mame2003 to the newest binary.
