Old Amiga 500/2000 games not working on A1200

I see everyone saying this, but I have only succeeded in getting a handful of games working in WHDLoad.

I even got a complete lha'd archive of a WHDLoad demo from another user (which worked), tried it on my amiga and no luck, same error.

I am running an A1200 + Microbotics 1230/50 with 64mb fast ram, 3+1 roms, and OS3.9.

I tried degrading, I tried booting from a floppy, I tried NoAutoVecs in whdload, I tried booting in ECS, removing my pcmcia ethernet card, nothing worked.

Yes, I have the correct A500 rom installed and in the correct location along with sKick tools.

I get the same replies over and over "it should work". Ok great, it should, but it doesn't.

Then of course you get accused of just being an idiot... um... ok I've owned Amigas since 1991, and worked as a software developer since 1992.  I'm not a noob to computers or the Amiga by any stretch.  It's not hard to install Whdload tools to C: and put kickstarts mentioned in the readme in DEVS:kickstarts.

Why it doesn't work is baffling... this is a Rev D (not D.1) motherboard.

Perhaps something is strange with my machine, but I have several WHDLoad games which do not work. Maybe it doesn't like how my memory is configured? I dunno.

SO I dunno... try a degrader before you spend a bunch of money on an accelerator and ram to use WHDLoad.

OS3.9 soft patches the rom on boot... maybe it doesn't liked a patched rom?

I am familiar with the roms and skick.  I've tested the roms by skicking into 1.3, but of course I couldn't boot because my HD is IDE on a 1200.

I did try no autovecs but I did not try nommu.

So yes, I have the correct kickstart (per the install docs for the state of the art installer), named correctly in the devs:kickstarts dir and I have the skick utils in c:.

Maybe I should make a video and put it on you tube.  Honestly how could anyone screw this up, it's easy.  It just doesn't work on my computer.

Which version of the state of the art demo are you running? There are two... one uses fastram or something, I can't remember the details.. the readme was sort of cryptic.

Today I went through a box of 100 amiga 500 floppies... of those only a few games worked on my A1200, even after setting CPU CACHE DISABLED and ECS chipset before booting.

Didn't try a degrader... didn't have much time today.
