Or...It's DMA could steal cycles between the CPU and your Microbiotics ram board?
This occurs without the Microbotics 8up! installed. The only mem in the system would be the 2MB on the A2091, the 2MB on the 2630, and the 1MB Chip ram.
Hmmm, it appears the A2091 doesn't even support DMA, meaning that without that onboard RAM it's totally dependent on the CPU for data transfer. Interestingly enough, the GVP-HCII does support DMA transfers, making it the superior board.
Slowdowns exactly like those you describe on 16 bit OCS/ECS Amiga's using WHDload aren't uncommon where software is coded to make use of chipram as opposed to fastram due to bandwidth issues on the 16 bit bus - However that's usually only an issue using 68030 and faster processors, and isn't affected by the storage device.
EDIT: Just downloaded the 'Audios' version from here and ran it on my A1200 using WHDLoad, it runs perfectly - It's actually a really good game!
Have you tried both of these versions?
https://www.whdownload.com/games.php?na ... ton=Search
- ACA 1232 accelerator with 68030 @ 40Mz, 128MB of fastram.
- 2MB Chipram
- internal IDE to CF adapter as HDD.
- Indivision AGA MK2Cr.
- AmigaOS 3.1
- 3.1 ROM.
- Latest version of WHDLoad (whatever that is).
