Firstly, I really love having the convenience of this package and not having to use my original hardware and disks more than necessary, thanks to @limi and all that put the work in to this.
Now I fired up one of my old favorites 'Batman the Movie' the other week and got all the way to the last level, then half way up the cathedral the game just crashed. Shame. Didn't think much of it but yesterday I played again and it did the same thing in the same location. Wondered if this was an issue with the original and if I was taking a different route through the level that I'd not done back in the day, so I fired up my A500 and original disks and played through the same route with no crash. Does anyone else come across this or is it just me?
