Thanks for the advice but that all sounds a bit complicated lol are there any beginnerish friendly tutorials available to do just what you suggested ?
I don't currently own legacy hardware so my only options are the A600 Gs and on my pc I have FSUAE im guessing I could do it through that?
I also forgot to add the original Xenon to that list it loads and runs but is terribly glitchy and unplayable
Cheers

I recommend getting the ADF versions of the games and demos you're having issues with.
For example, Mega-Lo-Mania is a one-disk game, so no need for WHD-Load. Use standard Amiga 500, Kickstart 1.3 setup in the launcher, use the ADF file, and it should work great!

Indiana Jones has a ton of disks, so here a custom Workbench setup / HDF is the best, but you could download the ADF's and run it that way too.
Alien Breed and Bass-o-Matic should do well with ADF files. Use standard Amiga 1200 setup with Kickstart 3.1 in the launcher for Tower Assault. Amiga 500, Kickstart 1.3 for Bass-o-Matic music-disk.
If something does not work with the ADF's, you can experiment with the settings, but a lot works with a standard Amiga 500, Kickstart 1.3 config.
Hope this was of help, and happy gaming!
