Downgrading an Amiga 3000 for WHDload?

[jammarob]

Hey guys, first post here and long time Amiga user and vintage computer collector!

I recently picked up an Amiga 3000 in a trade. I have always loved the Amiga 3000, but they have generally been very difficult to find in the US, and risky to buy because of the battery issue.

The Amiga I picked up has been "souped up" a bit. It had an A3640 CPU card, X-Surf NIC card, ZIP to SIMM adapter, GVP EGS video card, and IDE controller w/ CF hard drive.

Since I want this machine for the sole purpose of playing classic Amiga games, I have been forced to downgrade the CPU and video card in order for some games to work properly.

Is there a way I can keep the 68040 and still maintain compatibility? I hate to downgrade this thing, but I want it for a specific purpose, and it will be used heavily as a gaming machine.

Here is a quick video of my machine:

In all fairness I have only tested ~10 games, but the ones that worked seemed to perform more poorly than with the 68030.

An example: Turrican 3
68040: If I used the bomb, the CPU would slow down. CPU also slows in areas of graphically intense scenes.
68030: Smooth 60fps the entire game.

I am running the latest version of WHDload. Perhaps there is a patch?

Hi.

Just remove the 68040 card. Keep everything else :-). It'll work like a charm. I also had A3640 in my A3000D. Back then I had a lot of problems with WHDload (which disappeared once A3640 was removed).

Now I have CSPPC in this A3000D and (somewhat surprisingly) it is much more compatible than A3640 with WHDload.

Ahhh, good to know. Thanks .

I also had to remove the video card since I kept getting "Unable to initialise display" errors in WHDload. Once I removed the card and the drivers, it has worked great since.
