But that means if I want to play a game (in this case Hudson Hawk), I have to make sure to go into Early Startup and put the system into PAL mode, just switching to a PAL resolution isn't good enough.


So my question is, can't this be done directly with patching the whdload slaves? Seems to me the games mostly require the early boot because they ignire whatever the workbench screen is (in fact it creates its own on top, doesn't it?) Is there just an option I am missing? Any database out there of games that only work in PAL?
Don't use that jumper! Always use the early startup menu or some other tool to switch PAL/NTSC. That jumper seems to work fine at worst, but it causes AmigaOS to expect the correct crystal for that system instead of correcting for the different crystal.

E.g. if you have an NTSC A4000 and jumper it to PAL, it will assume you have a PAL crystal and time everything accordingly, even though you have an NTSC crystal. This will cause some subtle timing errors, in particular your system clock will drift.

If you do want to use that jumper, make sure you swap the crystal as well.
