Settings to emulate CD32 with TF330?

Danotaipano · 28 May 2021, 21:24

Looking to get an emulated setup as close as possible to my real CD32 w/ TF330 setup. So far I have the CD32 3.1 ROM set and 2MB motherboard ram. It won't accept 64MB accelerator ram without an accelerator board set but obviously there is no TF330 accelerator option. Is there something I can choose to come close? Any other way of approaching this? Any config advice appreciated.

You select 030 CPU and the other settings become available?

Thanks. Totally overlooked that. To emulate the ram of the TF330 would I set "accelerator RAM" to 64MB?

Accelerator RAM only works when you also add a specific accelerator card. Maybe you can get a good approximation by adding 64 MB or Zorro III RAM?

Thanks. It looks like that will be the best option. Just ran it and it seems right.

The address for the RAM will be slightly wrong. I think the TF330 maps it's RAM starting at $08000000 and ZIII Is mapped at $10000000 but nothing will care.

I don't know if WinUAE emulates RAM speed or ZIII arbitration but in theory ZIII RAM will be many times slower than accelerator RAM, at least on the real thing.

I think this can be modified with the option

uae_z3mem_start = 0x08000000

or something like that (not tested).

This is not emulated. So Zorro III RAM will be equally fast in UAE.

Thanks for the insights. Glad to have a setup that is close now.
