Substring:
arcade_15 or generic_15 can do 50Hz, you're not supposed to change that on demand.

Thanks for checking in, I must be using something incorrectly..
groovymame reports these video modes when in game using PAL PSX (groovymame pse -cdrom /path/psxgame.cue).
Generic_15 (too fast)
512 x 256 (H) 50 Hz
SR(0) 512 x 256p 57.065 Hz 15.750 kHz
Arcade_15 (too slow)
512 x 256 (H) 50 Hz
SR(0) 512 x 256p 58.484 Hz 16.200 kHz
PAL (correct)
512 x 256 (H) 50 Hz
SR(0) 512 x 256p 50.000 Hz 15.600 kHz
If Arcade and Generic both do 50hz shouldn't they pick the same as PAL mode to match the source?
Calamity:
Hi nicr4wks,
This looks like a problem with baseline MAME rather then GroovyMAME. Your log shows the PSX is trying to use 60 Hz modes even in PAL mode. That's incorrect. GroovyMAME just takes those 256p modes and tries to apply 60 Hz on them as requested, although it can't achieve that due to the 15 kHz limit (it falls close at 58 Hz). I've seen other examples of wrong PAL timings in MAME, maybe only NTSC platforms receive the most attention.
So you can create an specific ini file for psx games, adding (only) "monitor pal" and "syncrefresh". Forcing syncrefresh will be needed since GroovyMAME will still think it's running too slow and will disable it for this reason otherwise.

Thanks, I'm not going crazy then :lol
I've grabbed a couple of NTSC discs and they work fine, I think I'll just replace all of my disc images as the easier option.
EDIT--
I had to give it a go, created the pse.ini file, monitor switches to PAL mode OK, mame reports it's running in 50hz but the game still runs at over 200%, back to getting NTSC discs.
--- Code: ---monitor pal
syncrefresh 1
