Very weird super famicom import mod problems

I just modded a super famicom for 50/60 and lockout, something I've done many times.

This one however is giving super strange results.

I can play japanese games in 50 or 60hz no problem, but pal games wont boot. The cic has pin 4 earthed instead of at 5v.

Pal games will start to boot then freeze within a second or two.

Is the cic tied into the system in any way other than the two lines to the cart and the one to /reset ? Because /reset is not going low.

Its an earlier system with a removable apu, and an 18 pin cic
