use the latest MMUlib.
you only need to copy the content of MMUlib/Libs to your LIBS:
(68030.library and mmu.library should be enough, but copy all was quicker for me)
switch off the MMUlib (Y) in the ACA500plus menu.
save and boot.
Keep bug reports coming!
Here compare of loading Flyin' high, both machines has a 3.5.0 installed. Similar extra long loading with "no signal" is with Foundation and Nemac IV.
Here Napalm flickering screen.
And few which works just fine.

That side-by-side of Flyin' High, ist that against a native screenmode or against another P96-RTG machine?
Note that YT always cuts me off after exactly one minute when they see that I have effective ad blocking in place. I haven't watched this completely, as it's extremely inconvenient to run a downloader first, then open a player...

It is against P96-RTG machiene.
And the P96 version on that other machine is also V3.5.0, so we can assume that whatever causes this is located in the Indivision driver or core?

I have now 3 Amiga computers, with P96 3.5.0 RTG, and graphics cards are GVP Spectrum, xPert Merlin and Indivision ECS. Slow load is only with machine with Indivision ECS v4. TF536 IDE speed is about 3mb/s.
In my opinion, Indivision CDS v4 is the best thing to happen in the Amiga world in a long time. It brings graphics cards to every Amiga, and 256 colors are more than sufficient for running the operating system, and it’s noticeably faster than ECS with 16 colors. The speed, according to P96speed tests, already outperforms the Picasso II in many aspects, making it potentially capable of running games like Duke Nukem or Blood, provided we get a turbo card with a 68060 processor. One could also argue that Indivision ECS would make such a setup much more practical, as it no longer relies on ECS chips.
Our current working assumption is that the failing games (like the Napalm flickering) are hitting unused chipset registers. You have to know that all communication between the P96 driver and the framebuffer is happening through chipset registers that are normally unused. So it's hard to consider that a bug of the software when the bug only triggers on a certain piece of hardware.
If this assumption turns out to be true, we'll have to think about ways to detect and ignore such erroneous accesses.
In terms of speed, it'll always be limited by the bus speed of 3.5MByte/s, which is what Zorro-II is offering. However, that's "minus the bottleneck penalty", as we don't have random access to the framebuffer, but always need to talk to it through a small set of (otherwise) unused chipset registers. Our only chance to gain more speed is a blitter and using a fastmem buffer for a local copy - you have surely noticed the fastmem usage when opening an ECS V4 P96 screen.

Do all these setups use the same new version of the mmu libs? I'd like to make sure that the systems are as comparable as possible.

I'm not sure if they even use mmu libs? They have Phase5 and DCE accelerators, I thing they use Blizkick and Remapollo and libraries made by them. I'l check that when I get back to home.

All of them has same version of MMU libraies and P96. Game is started 320 x 256 RTG mode, left to Right GVP SPectrum, xPert Merlin, Indivision ECS.
