Still having trouble psx1

still cant make working backups of psx1 games
using clonecd,clonyxxl
ive downloaded the profiles for psx/libcript etc and psx has modchip, but the copied games stall at various points depending on the game?
acer 2410a crw
xp pro
768 ram
lg dvd rom
sony cdrom

in particular
nfs porsche 2000
le mans 24 hour

please help im making too many coasters
what the hell am i doing wrong?

Maybe it’s your write speed,

the old psx only reads cd’s that are written in 2 speed correctly
and then you still need very good media like philips or taiyo yuden
