An app that would speed up Chip memory

macce2 · 16 April 2022, 16:59

Hello,

Maybe a kind of noobie question;

but I'm playing around with CD32 Emulator program and ("real") CD32 games;
and have trouble running some of my favourites (of course, many
not-so-good games run fine :-D).

I think now it's Chaos Engine time !

However, the only way I get it to work is to disable Fast Ram
.
And that naturally affects the game overall speed considerably.

So, now I'm thinking, if it would be possible to somehow speed up
my Chip memory; even a little.
So, please recommend me something worth trying !

(One that comes to my mind is called Fblit (?!), but maybe there

are some alternatives...?! )

Chip RAM accesses are a hardware problem. The Buster chip contains no cache. Software can't fix it. FBlit uses Fast RAM instead of Chip RAM. It won't work on a stock CD32.

Oh, I see.
To be more precise; I'm running CD32 stuff on my A4000D..

Which CPU?

With 040+ chipset access is suboptimal. Could be better with the original 030 card.

I have a 3660 card with rev. 5 68060 cpu (with fpu) running at 50 Mhz.
I'm no expert, but I suspect that many of those CD32 games don't like 32-bit Ram.
Maybe I'm right...?!
So, is there a way to "fake" that memory as 24-bit or something ?!
