Yeah I couldn't believe how bad it was to get close to a decent frame rate (didn't remember it to look like that as a kid). Still a fun game to play.
Would love to replace my pal collection with nstc, doubt I'd ever get some of the classics in the boxed condition I have currently though (Zelda MM, Donky Kong 64 and Smash Bros among others have perfect boxes and Conkers BFD with a box at all goes for sill money).
Planning to get a copy of indiana jones and the infernal time machine on the 64 soon, sadly that will be cartridge only (boxed is over £100 which is too far) and it'll have to be nstc, only ever seen one pal version from Australia years ago(wish I had spent the £60 on it then, and I think it was Australian though it was before I went to uni when I saw it on ebay)
Prices for Conkers bad fur day are insane, even cart only is expensive. At least it's a RARE game, so the pal version is fine.
Switching over to NTSC is not costing me too much. I'm not a collector, so not bothered about the box, as long as the game works, I'm happy. Been pretty cheap so far.
NTSC console + accessories (psu, expansion pack, controllers & memory card) was £28 and the cart only games have all been between £5-10. Looking like Majora's mask will cost me £30 though and I'm not even going near Conkers bad fur day, cost is too much for me.
