Thanks
@Cluster I just used 21.c worked great
I added 38 games without folders. No errors on shutdown.
Majority were NTSC USA roms.
Super Street Fighter II added without any modification and worked great (used to have to change some preset ID from what I read)
I added Parodius which only had either Jap or PAL rom available. Used PAL rom converted to NTSC with IPS patch before uploading - works great
Ultimate MK3 had a report of audio issues after character selection screen. I used a PAL rom converted to NTSC - no audio issues from what I can see.
The only game which didnt work 100% is Rock and roll Racing as everyone already knows. Tried NTSC rom and a PAL rom converted to NTSC with IPS patch - both give a black title screen. You can press Start a couple times to get passed it though. I didn't want to add retroarch for just the one games' sake, so I'll probably live with it like that if i dont delete it
Very happy thanks for all the hard work and input from everyone!
