HD installs (not WHDLoad)
I have been trying to install a few games using their original installers (i.e. not the WHDLoad ones).
I am having a few issues with two installs, namely Monkey Island 2 and Historyline 1914-1918. In both cases, they install fine but won't run from an emulated A1200 HD - or rather, they will run but the graphics are utterly corrupted. They will run from an emulated A500+ HD, and from floppy on an emulated A1200. I'm sure I used to have both of these running fine from my real A1200 HD in the '90s - and in fact in the case of Historyline, when installing it even gave me the choice of a 68020 version (which I accepted). Am I missing something? (NB I tried NoFastMem from the Workbench, made no difference). |

If you turn off CPU caches and boot with original chipset in the early startup menu then MonkeyIsland2 will most likely work ok

On a real Amiga you probably used the Early Startup menu (hold down both mouse buttons during the boot), where you can disable the caches/switch to OCS. This worked fine for Monkey Island, not sure about History Line.
Edit: musashi was too fast. |

Excellent, that works fine! I do remember doing that sometimes on my real Miggy, should have thought of that myself really...
Out of curiosity, what's the technical reason that it will load from an A1200 floppy *without* that step, but on the HD it requires it? |

Most likely the Setpatch on your HD enabling all the features of the machine to the best level. Most games when booted from floppy don't bother with this.
Try just turning the cpu caches off and see if that makes a difference. You might not need to boot in 'original chipset mode' after all. |

No, just tried it and in fact it works with OCS + cache left on, but not the other way round.
Never mind, as long as it works! |

Cache is not the problem, fetchmode is. Setpatch enables AGA features and thus the graphics are corrupted. You can "fix" that by using a degrader such as TUDE.

I have just downloaded and installed TUDE from Aminet - my first impression is that it doesn't seem any less fiddly than simply using the early startup menu?
Maybe I need to take a look more at it... does it let you create a customised script for a specific game, so you can click on an icon for that game and have it degrade just for that game? |

So if I use IconX do I need TUDE as well?

Now, I think those instructions would have made a lot of sense to me 10-15 years ago, but now they just confuse me :-)
Can anyone offer a dummy's guide? |

Can't you use WinUAE to install those games, and come back to your Amiga to test them ?
Sorry if that sounds weak, but I managed to install quite a few games (which I packed & uploaded on my site) without much trouble thanks to WinUAE. Still, you would have to become familiar with degraders at some point, if I ain't mistaken (Tude is not the only one, you can "Aminet" for others). |
