Amiga 600HD game compatibility?

[orb85750]

If his A500 was PAL and his A600 was NTSC (or vice versa) then that would perfectly explain all his problems.

Did anyone install a PAL switch into your A500 or A600?

I just tested my Bionic Commando and Qix and they are both NTSC.  But you may have different versions than me.

Have you tried using Degrader (or similar util) to disable 1 MB of your A600 chipmem?  You don't normally need to do that but Bionic Commando is very old and its by Capcom so you'd better try it.

I have two A600 (one with the standard OS 2.0x (2.05?) and another with OS 3.1).  Both games fail to load properly in exactly the same way on both machines.  I have tried them with and without the trap-door memory expansion.  It makes no difference.  I have not tried a degrader or any softkick stuff from the web.  (At the moment, I don't have an easy way of getting such software onto the machine.)  I suppose that one should always have an A500 or A2000 on hand if one wants *seamless & easy* compatibility with some older games?

If you have 3.1 have you tried switiching to OCS on the early boot menu?
and trying Relokick is shurely easyer then getting another Amiga.

Degrader is a must have tool for running certain old games.

Hi there. I tried Bionic Commando and it worked on all my machines and configurations, from the 1.3 A500 to the 4MB 3.1 A600 and the 030 A1200s. I couldn't find a working copy of Qix to test, sorry. So I guess maybe your A600 might have dirty heads in the floppy drive, have you used a head cleaning kit?

Strange thing is that Bionic Commando has started working properly on all my machines.  That is a total mystery to me.  Qix still does not load on either of my A600 machines, but it works fine on my A500.  I've tried every possible permutation in the early menu screen, to no avail.

Cammy:  Thanks so much for your time and efforts!  I'm still astonished that Bionic Commando is now working for me too on the A600, even though I have not changed a thing.  (Can a floppy disk really fix itself?) Qix works only on the A500 not the A600 (weird) -- won't even boot on the A600.

It's possible that your A600's drive heads were a bit dirty, but through repeated use with these floppy disks, the grime has rubbed off enough to start reading the disks properly again. I was having all sorts of read errors with my Amigas before I bought a Floppy Drive Cleaning Kit from eBay. It's like a floppy disk with an abrasive pad inside it, you add some cleaning fluid to the pad and run the disk through the drive for 30 seconds and it really fixes things.
