As of Aladdin - did you have any fast memory enabled for it?
It seems that the game runs more stable without fast memory enabled.
I'm using the Prodigy crack (probably a good idea to specify which crack when using ADFs so we can compare like-for-like) - and with Fast RAM enabled it won't boot beyond the cracktro. There's a quirk with the Minimig's Fast RAM in that it disappears immediately after a Guru, and comes back after a subsequent soft-reset - so with Aladdin, the sequence is:
Boot with Fast RAM -> Cracktro -> crash -> Fast RAM disappears -> boot -> Cracktro -> game
Then the game runs OK.
Can you check one more game for me?
Name is Mick & Mack as the Global Gladiators.
The same appearance for me - don`t touch any buttons after loading (demo mode), and shortly the game crashes.
Without fast memory enabled game runs fine, crashes are with fast memory enabled only.
Again, the prodigy crack, and yes I can reproduce this. With Fast RAM enabled it boots, goes into attract mode, but seems to crash on returning to the menu.
I`am running AGA core on DE1-SoC hardware, and it seems it is very unstable at the moment.
Probably problems with the memory.
That is strange, because non-AGA design based on Rok`s DE1 port is running fine without any memory related problems...
Unfortunately there are aspects of the core's design that only just work, and all the TG68-based variants of the Minimig core suffer from a certain amount of build-to-build stability problems. A tiny change in a completely unrelated part of the core can be the difference between Fast RAM working and not. When I was tinkering with the Chameleon64's Minimig core I used Zeewolf 2 as a test case - if I can play through the first level without it freezing the build's generally a good one.
