I can confirm all this valuable information!
If you have a motherboard with ACPI (which used that cascaded IRQ2/9), some interface cards (especially PCI SATA controllers) will cause issues with Gateway.
The MM401 works with 99% of games, but has issues with the "hard cases" that probe for IRQ. Similar to the "hard cases" games that SoftMPU had issues with in the first version.
The good news is that there are only a few games like this. And personally, apart from the Legend games, they aren't very good 😀
So it's still a good card, but the price must be lower compared to a MPU401AT for example.

Add my pet hate:
Sound Blaster 16 and later doesn't support Sound Blaster Pro Stereo 😀
When only the digital part is affected, which affects basically zero games.
Yet everyone ignores the swapped L and R channels of the Sound Blaster Pro 😁
