I seem too be having issues with the game Apocalypse. The game boots up fine but in game the games mountain assets in the backround are glitched and missing details. I've tried plenty of settings but can't seem to get it running properly. I've tried the same ADF files on an emulator and it works fine so I'm not sure what I'm missing. I've attached a photo as well so it's a little bit clearer.

Are you running this in A500 or A1200 mode?

EDIT: can confirm it runs ok using A500 512+512 RAM + KS1.3 config. On A1200 I have the same glitches as you.

Thanks for your reply!

I am using the below settings and changed to 1.3. Mountains in the backround are still missing chunks. Not sure if I'm missing anything!

EDIT: Turns out I'm an idiot. I changed the CPU speed to that of a 500 and all is working.

My question is though, I've seen this game run on youtube video's on an Amiga 1200 just fine, so why isn't it the same for a Mister?

A1200 on minimig is not cycle exact and runs faster than original Amiga 1200. Could be the reason. Also, I've only tried it briefly on my standard A1200 config, maybe some settings change would help.

Anyway, its WHDLoad seems to work fine, why not just use that?

Thanks. I haven’t set up WHDload but I think I might have too.

Look for "MegaAGS" on archive.org, it's a ready made hdd image.

MegaAGS is super well done, by someone who really knows the Amiga. It's pretty much an ideal starting point.

Thank you!
